La Sportiva CYKLON CROSS GTX Review

Posted on by

©iancorless

The La Sportiva Cyklon with BOA® Fit System was a revelation on its release and without a doubt, it has been a perfect shoe for mountain adventures in challenging terrain. On first impressions, the Cyklon could almost have been mistaken for a lightweight boot due to the built in sock-liner which comes higher up the leg, to ankle height which has two purposes: 1. It keeps out debris from entering the shoe. 2. It provides additional support.

The CYKLON is a unique shoe in that it almost occupied its own category, a crossover between mountain running shoe and boot. IT excelled in challenging terrain with incredible foot hold, protection and a great outsole. Standout features were the sock-like fit in conjunction with the BOA/ Dynamic Cage which provided me with arguably one of the most secure footholds I have experienced.

Now, La Sportiva have stepped up the game with the recent release of the Cyklon Cross GTX. Living in Norway, this has been one of my ‘go-to’ shoe throughout the winter months when snow and ice have been my ‘normal’ running conditions.

In simple terms and for ease of clarification, imagine a Cyklon shoe wrapped in a water-repellent gaiter designed to keep snow, mud, ice, water, and other unwanted elements away from the foot.

Add an external zip allowing ease of access and a BOA® Fit System to ‘dial’ how tight or loose the fit of the shoe is, and an aggressive grip made from FriXion® White you have arguably, one of ‘the’ ultimate off-road/ mountain shoes when conditions are harsh.

My first impressions were one of disappointment, why were there no metal studs on the outsole as La Sportiva have on the Blizzard GTX (here)? Of course, I understood why, you really limit the market and the use of the shoe with studs, but here in Norway, you ‘always’ need spikes from November through to March and even April.

However, having messaged Jono Wyatt at La Sportiva asking the above question, his reply was as I expected, “We need to appeal to a larger market to make the shoe viable, but this outsole is designed to be used with AT Grip spikes to enhance grip on snowy and icy terrain.”

Problem solved – the AT Grip HERE is a multi-purpose, adjustable spike, it can be added to the sole quickly, guaranteeing maximum safety and grip on any type of terrain and under any conditions.

So, with my personal ‘needs’ covered re the spikes, I decided NOT to add the AT spikes and try the shoes in a multitude of terrain and as and when required, add micro-spikes (Nortec HERE for example) for ice conditions. Micro-spikes do provide more grip than studs, but the running experience is not as good as a specific winter stud shoe.

THE SHOE

©iancorless

If you used the Cyklon, you are going to love the Cyklon Cross GTX. For me, it takes everything I loved about the original Cyklon and adds a level of refinement that makes this incarnation a pleasure to wear.

Notably, the BOA® Fit System is in a different place to the original Cyklon and now it is clear of the ankle – a problem area for some.

©iancorless

Sliding your foot into the boot and it immediately feels like wearing a pair of gloves, without the BOA® Fit System adjusted, they already feel snug. Engage the BOA and twist and the foot is held snug with the option to micro-adjust tighter (or looser) based on personal needs or conditions. Then pull up the zip. The whole foot and well above the ankle is enclosed in a wonderfully snug Gore-Tex protection against the elements. The plus being that shoe adjustment can be done, ‘on-the-go’ with gloves on at any time while out on a run. Perfect!

©iancorless

Comfort level is extremely high. In all honesty, it’s a game changer for winter conditions. I do recommend using a higher sock that extends beyond the top of the shoe, it increases comfort. I also recommend that you use merino.

©iancorless

Many will say that there is no need for Gore-Tex in a running shoe. And usually, I would agree, especially for a shoe when water can enter below the ankle. Here though, the Cyklon Cross GTX comes much higher with a tight enclosure. It really does reduce what ‘can’ enter the shoe, and, in 3-months of winter running not once have my feet been wet. But go in water (deep) that extends beyond the top of the shoe and yes, water will enter, albeit much slower than any other shoe I have used. For clarity, I have run on many frozen ponds and puddles recently, often breaking through the ice to enter the water below, still no wet feet!

©iancorless

The grip is excellent on rock, mud, trees and all trail conditions, especially soft snow. Add micro-spikes for ice and you have a perfect ice shoe, albeit not as comfortable as a specific ice shoe, but on many occasions, I have gladly used this boot as an alternative, especially when encountering fresh snow with ice underneath, the boot offers more warmth and comfort.

©iancorless

Feel for the ground is superb. They are cushioned but not too much. They combine comfort and excellent proprioception so that you feel at one with the terrain and always in control. Propulsive phase is superb and all-around comfort is magnificent. The Cyklon Cross GTX feels so good that I’d love to use them beyond the winter months, they would make excellent mountain shoes for all-year BUT I fear, they will be too warm in late spring and summer.

©iancorless

The toe bumper is robust and amazingly protective.

Despite the obvious appeals for winter and mountain running, the Cyklon Cross GTX is ideally placed for ‘fast-and-light’ alpinism when a normal shoe just wouldn’t cut it, think of Monte Rosa Skymarathon as a prime example.

A neutral fit I suggest you size up. I find that with La Sportiva I always need to do this; I am usually an EU 44 (UK9.5) but with La Sportiva I am in EU 45. Weight of an EU 45 is 382g which is quite incredible for a shoe with such solid build. Drop is 8mm.

Looks are awesome – the classic La Sportiva yellow/ black is stunning.

CONCLUSION

The La Sportiva Cyklon Cross GTX gets a 9.5/10 from me. Why not 10? Well, I’d love to see them ‘with’ a winter spike, but I fully understand why a spike is not standard. At least La Sportiva have thought of this with an appropriate outsole and the option of AT spikes.

Amazing foothold, amazing grip, warm, durable and dare I say, bullet proof. This is a shoe that makes me smile and want to run in harsh, cold, and tough conditions. BOA is the perfect fit system here and arguably it’s a best-case scenario allowing the user to adjust the shoe when running, especially when wearing gloves on.

The ride is predictably stable, firm, protective and suitable for any terrain and they excel in mud and snow. Ground feel is superb with adequate comfort.

They look awesome and surprisingly streamlined. When zipped up, they fit snug, some would even say tight, which only adds to the secure and warm feeling.

They are not cheap at 260 euros, but this is a specific bespoke shoe and if used as intended, they will last year-on-year for many winters.

Quite simply, one of the best, (if not the best) winter shoes I have ever used !

adidas Terrex Agravic Tech Pro with BOA Winter Shoe Review

Posted on by
3

2021 has been the year of adidas for me. The three stripe brand with the distinctive TERREX logo has made great progress in the trail, mountain and ultra world with some stand out shoes.

Early in the year, I called out the Speed Ultra as not only my favourite shoe but arguably, one of the best shoes I have ever used. Three pairs on and I still think the same. Without doubt one of ‘the’ shoes of 2021.

Recently, I received a pair of the adidas Terrex Agravic Tech Pro with BOA.

Now I have to say, I was initially frustrated, here in Norway we still had ‘decent’ weather and this boot would have just been way too much for the conditions… Gladly though, winter arrived in November and we have plenty of snow, ice and temperatures well below -10. A perfect testing ground.

The adidas Terrex Agravic Tech Pro is distinctive! The shoe does come in a more sedate and classy looking black with hints of red, I received the ‘stand out’ look at me colour way of black, Mesa and Halo Blue.

Let’s be clear, this is a shoe for very specific use and that I love! Far too often when it comes to winter, I am compromising trying to make the best os shoes that are not specific for the task. Here in the adidas Terrex Agravic Tech Pro you have shoe that is designed for harsh, rough, wet and cold conditions. And trust me, when it is -20 snow and ice, warm feet make a very happy runner.

The adidas Terrex Agravic Tech Pro has some really incredible design and engineering. Inside the boot is a Terrex Agravic shoe with the usual adidas comfort, continental outsole and Boost cushioning. The shoe is wrapped in a water repellent envelope with durable front closure zipper and on the outside the BOA dial to provide tension and security.

The BOA brings a welcome development. Often winter boots like this incarnation by adidas have a laced shoe inside. Therefore, you put the boot on, lace up the shoe inside and then zipper the enclosure. The downside of this, is that when out on the trail, should you need to adjust the lacing, you must unzip the boot and then do the lace… Maybe no big deal you think? Trust me, if it is below zero, freezing cold and your hands are already feeling somewhat numb, the last thing you want to do is take gloves off and tie laces. Here in the adidas Terrex Agravic Tech Pro

That problem is solved as the whole shoe, inner and outer is tightened and released by the BOA on the outside of the shoe. It’s push in/ twist and pull out/ twist for less or more tension is just perfect even with gloves on. It may well be one of the most practical and logical reasons to use a BOA adjustment. It really is spot on! Using the L6 platform, with a L6 dial and TX4 lace, this is a perfect winter shoe fastening system as it protects against dirt contamination. You may well wonder about durability and strength, but the L6 uses a bayonet and cartridge system which is designed to release without breaking. If it releases, you can insert the cartridge back into the bayonet. The TX4 lace is also flexible and light weight with low friction. It’s the best BOA system I have used thus far.

As the number on the side suggests, ‘420’ this refers to weight in a standard UK8 size, 489g for my UK9.5/EU44 . This is not a lightweight running shoe, but what it is is a durable beast to offer support, warmth and protection in the harshest environment. Be that running in snow, climbing, running trail or even crossing a glacier (with the appropriate cramp on).

You may think it’s a boot and to an extent it is, however, because a running shoe is inside, the adidas Terrex Agravic Tech Pro has a completely different feel. It has the best of both worlds!

An 8mm drop sits perfectly in a shoe like this providing the potential for all-day comfort. Protection both at the fore and rear is excellent, there is some stability in the shoe but flex, particularly behind the metatarsals is great, important for when running and climbing.

Cushioning is Boost which is durable in could and challenging conditions, importantly it does not harden in the cold. There is an EVA frame for stability. Front rock protection is good and the outsole is grippy Continental with 4mm lugs.

The outsole does leave me perplexed. I am not complaining about the grip, BUT I would have liked to have seen winter spikes on a shoe like this. In soft snow the spikes cause no hindrance but if you hit ice, they are a life saver. I understand why adidas would choose NOT to add winter spikes: it basically narrows the market. So, this boot would require one of two options for me:

  1. Add a micro crampon that could be taken on and off as required.
  2. Add studs myself.

Currently I have used a micro crampon which provides the grip I need BUT the running experience is nowhere near as good as an outsole with studs. With a studded outsole you have the best of both worlds, the outsole grip and the stud. With a crampon, you have just the metal spikes which can provide a much harsher run.

IN USE

You need to invest a little more time putting this shoe on. Make sure you slide your foot in to the inner shoe correctly, adjust your socks and make sure the heal feels correct. On a sizing note, I use an EU44 and I would say these are arguably a little larger. This is a good thing! I have used these with Merino liner socks and Sealskinz over sock and the sizing has been great. So, keep this in mind.

Once the foot is inside and comfortable, zip up the outer. It has sock-like fit. This can be a little challenging to start but once closed, it already provides a snug fit. One thing to note, I wouldn’t want to be trying to zip up the shoe, outdoors in -10.

There is a velcro adjust collar which you tighten, this helps stop or reduce anything going in via the top of the boot. Now adjust the BOA. You do this by pushing in the dial and then rotating. The more you rotate, the tighter the hold. It hold really well and importantly this can be adjusted ‘on-the-go’ with just a quick turn. No messing with laces, just turn. A really important feature for cold conditions when hands are not functioning as normal.

On paper, the adidas Terrex Agravic Tech Pro is a heavy run shoe BUT it feels and acts much lighter. It’s a pleasure to wear. It is agile, has bounce, feels extremely protected, is snug and warm. You really feel as though you have bullet proof protection.

The toe box has width and plenty of comfort. On a scale of 1-5 (5 being wide), I would say they are a 3/4.

One note on BOA, I always feel as though I need to over tighten to get a score feel. It’s no different here in the adidas Terrex Agravic Tech Pro BUT I advise getting tension ‘close’ to how you want it and then run for say 10-minutes or so. Then stop and adjust. Why? Quite simply, in winter and cold conditions, you don’t want to over restrict blood flow. Feet and hands get neglected to keep the core warm in winter, no need to add to the problem with over tightened shoes. BOA is great for this as you just turn to tighten, takes less than 1-second.

While water resistant, they are not waterproof and therefore over prolonged use, partially if you submerge in water, you will get some seepage.

Warmth is good especially with merino socks. This is an active shoe and therefore is designed for the user to be moving at pace, either walking, running or climbing and therefore generating blood flow and warmth. Standing around in snow doing nothing, the adidas Terrex Agravic Tech Pro eventually allows the feet to feel chilly; any shoe/ boot would!

The midsole is firm and cushioned but not plush. As you would imagine, this shoe is trying to balance comfort and protection and it does it extremely well. They are stable and predictable and he Boost works exceptionally well, even in extreme cold with the EVA frame adding extra security. It’s not a fast and light shoe, to be honest I never expected that. The adidas Terrex Agravic Tech Pro is all bout durability, protection and comfort in harsh conditions and it excels at this. The alternative would be a boot which would not have any of the unique characteristics of this shoe, especially for a runner.

Outsole is Continental and having used countless adidas shoes, I know is tried and tested. The 4mm lugs sit in that perfect middle ground providing traction on trail and work well on road if required. I did wonder if the outsole lugs should be more pronounced, say 6mm? This would certainly help in snow. I have already mentioned the omission of winter spikes which for me is a disappointment BUT I fully appreciate that I may have specific and selfish needs.

I have tried the shoe with Snowline Chaisen Trail (as photo) and also Camp Ice Master which is a more substantial  crampon, ideal for glacier and steeper travel. Please note, all micro crampon/ boot combinations have limitations, the adidas Terrex Agravic Tech Pro is NOT a mountaineering boot.

CONCLUSION

If you have rough winter weather, be that wet, cold and muddy or snow, ice and freezing temperatures, the adidas Terrex Agravic Tech Pro is a great addition to your run shoe collection. Only you can decide if the cost (£220) is worth it. For me, they are most definitely worth it and if they had studs, I would use them for every winter run.

The combination of a proper run shoe inside a protective gaiter is not new, but adidas have done a great job in making this a durable, warm and protected package. The BOA adds to the USP as it allows for constant adjustment ‘on-the-go’ with no need to remove gloves.

Versatility is a key feature. You can use them for winter hikes, running, add a micro crampon and you can handle ice and due to the build of the shoe, they will take snow shoes too. This is a great alpine shoe and here in Norway, it’s almost THE perfect shoe. You can mix hard and rock terrain, transition to snow and then add a cramp on to cross ice on with excellent comfort and security.

The comfort, secure hold and cushioning is all excellent and they feel considerably more lively and agile than the weight would suggest.

There is little not to like in the adidas Terrex Agravic Tech Pro. Weight will always be an issue BUT this is not a normal run shoe and there has to be a penalty for all the added comfort and protection. When you take that in to account, this is not a heavy shoe, especially when you consider the options. It certainly runs considerably lighter than you would expect.

La Sportiva Cyklon Review

Posted on by
20

The La Sportiva CYKLON is here. Renowned for shoes that perform in mountain, challenging and arduous terrain, La Sportiva have moved up a level with the CYKLON collaborating closely with BOA® Fit System to provide a new mountain running shoe with a difference.

Available in multiple (4) colour options, the standout for me is the classic and directly recognizable La Sportiva colours on black/yellow/red which has always been pleasing to the eye and one that grabs attention.

The CYKLON on first impressions could almost be mistaken for a lightweight boot due to the built-in sock-liner which comes higher up the leg, to beyond ankle height which has two purposes: 1. It keeps out debris from entering the shoe. 2. It provides additional support.

The CYKLON has slightly unusual sizing, I take an EU44 (UK9.5) in all my shoes, the same applies here in the La Sportiva, but this comes out as a UK9.5+ – I guess a 9 and 2/3rds. It works fine and, in all honesty, I would say that little extra room was welcome.

They are not the lightest shoes, 340g for an EU44, but on the foot and running they feel superb, secure, and strong. They certainly don’t feel like a 300g+ shoe. The weight is listed as 315g for ‘standard size’ which is typically UK8/ EU42.

Drop is 8mm and cushioning is 20mm at the front and 28mm at the rear providing excellent protection for tough and challenging terrain.

Designed to excel in mountain environments, 6x world mountain running champion, Jonathan Wyatt (who works at La Sportiva) has been closely involved with the development of the shoe with all important athlete feedback. In his words, the CYKLON is the next step from the extremely popular MUTANT. While similarities can be seen, particularly in the outsole, the CYKLON moves the shoe design on significantly. The addition of BOA® significantly changes things too and the two brands have worked together to develop and tweak to ensure that the shoe is as perfect as it can be.

It’s often easy to get bogged down in jargon when discussing a shoe and all brands have their names to describe key features, here in the CYKLON ‘Dynamic Cage’ is a buzzword and one of the key USP’s of the shoe. Working with a supremely comfortable and secure sock-like fit, the Dynamic Cage holds the foot like no other shoe I have tried, it is as good as VJ Sport ‘Fitlock’ but at the same time, completely different.

The midsole is EVA Memlex which helps absorb shocks, offers protection through double density and it also has stabilization inserts.

The outsole is FriXion XF 2.0 with 7mm lugs which clearly shows what the CYKLON is for – challenging mountain terrain that includes mud, snow and/or ice.

The upper has 4-way mesh and has a multi-layer side panel overlay. It’s all about foothold and protection and while it’s too early to comment on longevity and life, the CYKLON upper screams durability. This is only emphasized at the form of the shoe with a real sold toe bumper and the rear where the overlay gives way to the sock-liner.

THE SHOE

The CYKLON is actually a little tricky to get on, a little like putting neoprene socks on. It is worthwhile just taking an extra minute to ensure you have your foot in the shoe correctly and that the sock-liner is adjusted, a yellow tab helps you pul them on. The sock liner does come above ankle height, so, you may want to consider what sock length you use.

First impression is the incredible hold of the foot. This is even before the BOA is adjusted. It’s like sliding your foot in to shoe gloves. Turning the BOA, the shoe tightens to the foot via 4 key points. The bottom one is fixed, the other 3 are independent and move according to foot shape and applied tension from the BOA – this is the Dynamic Cage. Quite simply, the more you turn the dial, the more secure the foothold. I have tested multiple shoes with a BOA system before and one of my constant complaints was that I often felt I couldn’t get the foothold I wanted, not so in the CYKLON. The foothold here as stated previously, is up there with the best and this is due the sock-fit and the Dynamic Cage working in harmony.

I was worried at the rear of the shoe where the overlays for the heel stop and the sock-liner starts. Hold for the heel is excellent but I did wonder if I would have an issue? The answer was no. Hold and comfort was superb.

There does feel just a hint of arch support in the shoe. It’s nothing crazy and for someone who uses neutral shoes, it caused me no issues or problems. As mentioned, there is some stability added to the midsole and this all comes down to La Sportiva making sure you have a secure and resilient shoe that can handle the terrain that the shoe is designed for.

Width up front is a 3 on a 1-5 scale, 1 being narrow/ precision and 5 being wide. For me, a 3 fit it about right based on the intended use – technical and challenging terrain of mid distance.

The 20-28 cushioning is more than I anticipated as is the 8mm drop. When running on mountain, skyrunning and technical terrain a shoe with more ground feel and lower drop is usually preferable, say 18-24 with 6mm drop! However, the CYKLON excels on the rough stuff giving a very confident and secure feel and they adapt to quick changes of direction. The FriXion outsole with 7mm lugs works superbly. Interestingly. AT Grip Spike can be added to the outsole for use on icy ground. The footbed is Ortholite and specifically designed for mountain running.

IN USE

I have 124km in the CYKLON and this is a first impression review. There are two key features which I want to rave about:

The sock-like fit is superb.

The BOA system Dynamic Cage is incredible and holds the foot like no other.

The 2 features above are stand out and on all my runs, this security and foot hold has put a huge smile on my face. Tree roots, rocks, mud, climbing, descending and so on, the CYKLON just holds the foot and gives complete confidence. The downside is that all these layers and hold make the shoe run hot! I could feel that the heat generated when running had difficulty to escape despite the breathable upper. Quite simply, the anti-abrasion mesh and TPU reinforcements all add up. I did a challenging and technical 26km run that had me out for 2h 45min and while I had no pain, irritations or discomfort, my feet were noticeably hotter than in other shoes.

BOA is always going to turn some people off, I get it, laces work, are simple and you snap one, you can easily replace it… BOA has come a long way in recent years and here on the CYKLON I can see the advancement and in all honesty, I don’t think the foot hold in the CYKLON would be as good if provided by laces – the BOA brings a whole new dynamic to the shoe and I am completely sold. For perspective, BOA do offer a full guarantee on the system. Here they use a L6 dial and TX4 lace and I asked the question, ‘what if a lace breaks?’ Quite simply, BOA replied, ‘A lace snapping is highly unlikely, however, should it happen, you can just tie lace together (as you would with any lace), and this will work.’ One of the great things about BOA is the ability to adjust quickly on the go, especially useful in cold weather. We all experiences laces coming undone, it’s a pain to stop and do them up again. With BOA they will not come undone and if you need to tighten, you just stop, bend down, turn the dial and off you go.

Cushioning in the CYCLONE is on the firm/ protective side and considering the intended use, probably comes as no surprise. However, I did expect a little more bounce? However, with 50km on the shoes, I found them more responsive – they are not plush or bouncy. They are solid, secure, and reliable and trustworthy. Again, this is a shoe designed for mid-distance and not long distance. Certainly, I found 3-5 hours perfectly comfortable. I haven’t gone beyond that time in the CYKLON yet. There is some support in the shoe and that can be felt when the terrain becomes very challenging, it helps guide the foot, not control it.

The outsole is solid, reliable, and durable. It’s ideal for mountain terrain and excels on rock and technical terrain, particularly in conjunction with the foot hold and BOA system.

SUMMARY

The CYKLON is somewhat unique in that it almost occupies its own category, almost a crossover between mountain running shoe and boot. It excels in challenging terrain with incredible foot hold, protection, and a great outsole. Standout features are the sock-like fit in conjunction with the BOA/ Dynamic Cage which provided me with arguably one of the most secure footholds I have experienced.

Intended for mid-distance, I see the CYKLON as a great shoe for any mountain adventure, long or short. It’s crossover capabilities and weight would have me choosing this shoe over a boot, particularly if I wanted to hike fast in the mountains.

Climbing and descending is solid and reassured.

All-in-all it’s a great shoe and La Sportiva fans, particularly those who have used the Mutant are going to love.

The downsides for me are that the shoe runs hot and particularly in summer months this could prove to be an issue? It’s not the lightest shoe and despite the amazing foot hold, it probably doesn’t feel like a nimble and light race shoe, so, if looking to race, another shoe may be preferable? Day-to-day mountain adventures, fast or slow, the CYKLON will be a great addition to any shoe rotation.

La Sportiva VK Boa® Shoe Review

Posted on by
13

Italian brand, La Sportiva, take running shoe specialization to the next level with the VK Boa®, a shoe that is specifically designed to go mountain as quickly as possible in the lightest package available.

To understand the shoe, you need to understand its purpose.

Dolomites VK, Italy.

The VK in the name refers to Vertical Kilometer® a sport created on the slopes of Monte Rosa in 1994 by Marino Giacometti, the founder and creator of the sport, Skyrunning. Governed by the ISF, the International Skyrunning Federation, the sport is simple in concept – To cover 1000 vertical meters in a course that is less than *5km long with average incline of 20%. Double (2000m) and triple (3000m) VK’s also exist.

Initially created for scientific research the VK concept grew and it has become a staple in the calendar of skyrunning with its own specific calendar and relative world and European champions. Often, a VK would be added on to a race weekend that included another longer race, the Dolomites being a prime example where a VK would take place on Friday and a SkyRace on Sunday. Competitors often do both races. The world record stands at 28-minutes 53-seconds by Philip Goetsch set at one of the steepest VK’s in the world, Fully, which covers the 1000 vertical meters in a course that is only 1.92km long. The finish line is 1500m altitude.

The VK sport was created in Italy and the La Sportiva brand was born in Italy, the synergy between the two is obvious.

To create a specific shoe for VK not only shows the demand, especially in Italy, for such a shoe, but also the enthusiasm for the sport. The 2020 the Vertical Kilometer® World Circuit, managed by SkyMan, was cancelled however, the ISF have confirmed the sport will continue and recently they announced a new 2VK circuit – HERE

La Sportiva VK Boa®

Like track spikes, the VK Boa is a very specific shoe.

It’s all about minimal weight, secure foot hold, grip and a package that turns the eye. I have to say, the classic black/yellow/red of La Sportiva has always appealed and here in the VK Boa® that is taken up a notch to make what I think is a really ‘sexy’ shoe.

The striking look pulls you in and then you pick the shoe up, at sub 200g for a standard UK8 (230g for a UK9.5) this shoe is amazingly light.

The upper is just one seamless sock with a narrow opening from which one inserts the foot. Three wide straps come across the shoe to create the foothold and structure and conventional laces have been removed to be replaced with the Boa® rapid closure system.

A minimal toe bumper offers toe protection.

The outsole is a story of two halves: the front using a black semi-aggressive grip with relatively small lugs (25) the rear has a different configuration in red.

Cushioning, as one would expect is minimal but surprisingly more than I expected.

Drop is 4mm.

The shoe is described as being ‘universal’, but I do feel some support under the arch.

Sizing is true to size.

The Shoe

Firstly, getting one’s foot into the shoe is a little tricky. This shoe is designed like a Formula 1 car and as such, excess is taken away. One you have your foot inside, take time to wiggle your foot, make sure your heel is in the correct place and ensure that you pull the upper up, just like a sock.

There is no tongue. Tightening the shoe is done from the Boa® closure by turning the dial. Do this slowly making sure the laces sit where you want them. Taking time here will ensure a great foothold, particularly on the important Navicular bone.

The heel box is really impressive and rightly so for a shoe that is designed for going uphill. A lack of secure hold at the rear and it would prove really problematic. I’d go as far to say that the VK Boa® has the most secure and tight-fitting heel box of any shoe I have tried.

The toe box area, just like socks, is free of any reinforcement and extremely slipper like. It is not narrow and not wide, but the freedom of movement offered by the bi-elastic mesh would make this shoe work for most people. La Sportiva call it Low Volume which is designed for a tight fit following foot shape.

The outsole is very clever, La Sportiva know that when doing a VK, the front of the shoe is used almost 100% with only occasional use of the shoe rear. The outsole reflects this with two different grips and notably there is ‘rock-guard’ only at the front of the shoe. The outsole is designed to have as many contact points as possible. Frixion Red is a combination of grip, long-lasting wear and shock absorption. VK’s take place on grass, rock, stone, scree, mud and even ice, the outsole does a great job of handling each of the conditions.

The cushioning is compressed EVA and I was surprised how much cushioning was in the shoe, but it is designed for softer ground where the requirement for shock absorption is reduced. Completely understandable for a shoe designed for VK’s.

In Use

This is a very specific shoe and as such will have a very reduced market. It’s not a shoe that can-do multiple tasks, having said that, they VK Boa® may work exceptionally well on a short mountain race but downhill support and comfort would be compromised.

This shoe is designed to go up.

Considering that most VK’s are completed in 30-minutes for the elite men, around 35/40 minutes for the elite women and then 60 to 90-minutes for mortals, you get a picture that this shoe needs to be light.

Light they are; super light! They really do fit like gloves and I am still surprised at how well they hold the foot. I have had mixed experiences with Boa® closure systems previously but on this shoe it all clicks together. The Boa® (L6 type) system is a logical closure step allowing the top of the shoe to be free of seams and additional stitching and the three straps, just like in cycling shoes, comes across the foot to create a really superior hold. It’s all about efficiency and it makes a really nice aesthetic.

The shoes are extremely flexible and notably they excel in three areas. 

  1. The hold in the heel area is superb, no, it is brilliant! The lack of slipping in the heel area for a shoe designed for going uphill is absolutely crucial and the VK Boa® may well be the best I have tried.
  2. The soft and flexible upper manages to provide enough structure and support but allows the foot to move and bend in the propulsive phase without restriction. Crucial for a VK when pretty much the entire race or run will be undertaken on the front of the shoe.
  3. The outsole is designed for purpose and I love the specific grip and rock-guard just for the front of the shoe where it is needed.

Precise, reactive, great foot hold, excellent proprioception and extremely flexible, the VK Boa® really is beautifully designed for the task it was created for.

Conclusion

This shoe is not for everyone and I applaud La Sportiva for creating such a specific shoe. Light and minimalist, they excel for the designed purpose and there is little to fault.

They look great, the Boa® system is a superb addition to the shoe that maybe is the best use of this product I have seen in a running shoe.

RRP is 170 euro, so, they are not cheap. However, such a specific shoe will have a long life as they will only be used for VK racing or training. More often than not, VK’s are located close or near cable cars, so, the need to run back down is not required. Having said that, if one does need to run down, the VK Boa® does lack some of the structure a conventional run shoe would have, so, that needs to be considered.

If VK’s and going uphill as fast as possible is your think, the La Sportiva VK Boa® are most definitely worth checking out.

Tom Evans – Zero to 100

Posted on by

It was incredible. The preparation. The event. The course. The journey.

The process. The outcome.

I knew I always wanted to challenge myself over 100 miles…I just never expected it to be in this incredible race. I was privileged to have qualified to race so to have a Race Crew and Filming Crew follow my journey over the race to an unexpected end was amazing.

I had the immense pleasure to meet Tom at Marathon des Sables, he was a complete unknown who on day-1 of the race, rocked the apple cart and the Moroccan dominance of the race. Myself, the rest of the media and all the runner’s in the race were asking the question, “Who is Tom Evans?”

By the end of the MDS, we had an answer. He placed 3rd and in the process, the ultra-running world welcomed a new star in the sport. He was without a sponsor and still a captain in the army.

Post MDS, we discussed opportunities and how Tom could achieve his goals. I was fortunate that Tom decided to join me on my annual Lanzarote Training Camp. He joined us as a coach and ambassador.

It was easy to see Tom’s ability. Few on the camp could keep up with him and those that could went on to race well at the following Marathon des Sables. In particular, Gemma Game who made the podium.

Following our camp, Tom joined me in Costa Rica for The Coastal Challenge. I was keen to see him race once again over multiple days and this time without being in a self-sufficient manner. I arrange the elite field and I was determined to give Tom and the rest, a hard race. Hayden Hawks, Timothy Olson and Marcus Scotney amongst others toed the line.

Tom arrived to race and it was clear from the off, he had an agenda. He had researched the race, looked at the stages, checked the times and not only did he have ambitions to win the race, but also set a new course record. Hayden and Tom raced head-to-head day-after-day but victory and the CR was never in doubt, Tom dominated.

It was time to set the goals higher and work to higher objectives. Tom represented his country and placed 3rd at the world championships. He dipped his toe in skyrunning races going head-to-head with skyrunning world champion, Jon Albon. But all along, the big goal was CCC part of the UTMB races.

Just prior to CCC, Tom signed a deal with Red Bull. I was fortunate to join Tom at his family home in the UK and document his training.

At CCC, running the perfect race, Tom closed on the lead in the latter stages of the race, forged ahead and won the biggest race of his life. A sponsorship deal with adidas Terrex followed and the dream of Western States started to fall in to place.

Zero to 100 tells the story of Tom’s inaugural 100-mile race, the iconic Western States in the USA. To place in the top-10 here would have been an incredible result, but Tom went on to place 3rd and in the process run under 15-hours. He trained in Ethiopia to prepare and you can listen to the whole process in episode 174 of Talk Ultra listed below.

ZERO TO 100

Process not Outcome

Tom has always discussed his thoughts on training and racing and one element that always runs true is ‘Process not Outcome.’ His ability to focus on the prize, dedicate himself to the task and take running to a higher and higher level is all down to his dedication and professional approach.

In 2020, Tom will target new races, new goals and new experiences. One thing is for sure, after victory at Tarawera Ultra in New Zealand early in the year, Tom is in the perfect place to fulfil his dreams. I would expect no less…!

2020 calendar subject to change based around Covid-19

Over the past couple of years, I have documented Tom’s progress via my podcast, Talk Ultra, you can listen to the episodes below:

adidas Terrex Agravic Boa Shoe Review

Posted on by
4

adidas have been making Terrex shoes for years and Luis Alberto Hernando has been flying the adidas flag for most of them. It’s fair to say, that a runner such as Luis always gave the Terrex brand credibility.

However, I always felt he was a lonely figure fighting the big brands and teams from Salomon, The North Face, La Sportiva, Scott and so on!

Well, that is all changing. adidas with the Terrex brand are moving in to the trail world in a big way. Certainly Dmitry Mityaev and Ekaterina Mityaeva were the start of that process. Then Timothy Olson. Now, with the closing of 2018 and the start of 2019, Tom Evans, Holly Page, Sheila Avilés and many more are joining the line-up.

Listen to Tom Evans talk about his 3rd place at Western States HERE

 

I witnessed adidas’ plans at the recent Infinite Trails (here) in Austria and here did I not only get to see and try the new apparel, I also got to see some of the new shoes.

One of those shoes being the Terrex Agravic Boa. I was intrigued with this shoe as my initial test/ use of a previous adidas Boa shoe left me somewhat unconvinced.

I spent time at the Boa® stand (at the Infinite Trails expo), discussed the development of the Boa system and got a hands-on- feel of the Agravic. The development was marked but I couldn’t try the shoe as sizes were limited. Gladly that was rectified when Boa sent me a pair in the post.

First off, I love the look of the shoe is stealth black. This broken by a  camouflage black/grey/white section before the stark white of the shoes Boost cushioning. The black colour comes from a special dye process (see below) that is more ecologically sound.

They are light shoes with a wide toe box, reinforced toe protection and then a complex series of overlays that give the shoe structure which is all pulled together by the Boa® lacing system.

A notable feature is the shoes sock liner. This is arguably the most immediately comfortable shoes I have slipped on. One could easily use these shoes without socks the liner is so good. It is completely seamless so the risk to rubbing/ abrasion is greatly reduced. This also extends to the heal – a firm hold without rubbing is a winner.

Cushioning comes from adidas Boost technology and one can feel adidas’ road pedigree in these shoes. The cushioning is plush and responsive with 15mm at the front and 22mm at the rear. This gives an unusual 7mm drop. I say unusual as 6mm or 8mm is ‘standard’ in shoe drop across all brands.

The outsole is the amazing Continental rubber. The tread is by no means aggressive and this is certainly a trail shoe designed for fast running on non-muddy trails. But on hardpack trail and rocks, wet or  dry, the grip is excellent. I must add here that in my cycling days, Continental were always my tires of choice!

Specs:

  • Sock-like construction hugs the foot
  • Weight: 285 g (size UK 8.5)
  • Midsole drop: 7 mm (heel 22 mm / forefoot 15 mm)
  • Product colour: Core Black / Cloud White / Active Red
  • Regular fit
  • Boa® Closure System for micro-adjustment and secure and consistent hold
  • Abrasion-resistant textile upper
  • Continental™ Rubber outsole for extraordinary traction in wet and dry conditions
  • Responsive Boost midsole; Moulded sockliner

IN USE

These shoes are wonderfully comfortable. They feel so good as soon as you slip them on and this all comes from the sock liner. There is an immediate notable feel that the toe box is wide and spacious allowing for good toe splay. So, if you need wide trail shoes, add the Agravic to your check-out list.

My previous adidas Terrex shoes left me undecided or should I say, unconvinced by the Boa closure system. Have to say, the Terrex Agravic Boa® has changed that. The Boa® works great here and that is for two reasons:

  1. The adidas shoe is a much better fit and therefore this makes the work of the Boa® so much easier.
  2. The overlays that add structure are well placed and designed allowing the Boa® to pull tight, hold the foot and keep it secure.

I am experienced with the Boa® system, it has been the ‘go to’ on cycling shoes for years and my first experience with run shoes was way back in 2008, I think?

There will always be an argument that laces are easier, and yes, laces do a great job and it’s hard to argue against the tried and tested method. But the Boa® here has me hooked. Speed both on and off is great. Quite simply slide the shoe on, push ‘in’ the Boa button and turn. The laces pull tight and continue to pull tight until you stop. To loosen, pull the Boa® button and voila, the laces release immediately.

I had problems before getting a firm hold on my foot. Not here. The shoes have three lace points on left and three lace points on the right. As you tighten, they pull in. I really like my foot to be held well, especially on technical terrain and here in this Terrex Agravic Boa® I am very happy.

Toe box is roomy, but not too roomy. They are very comfortable upfront and the toe protection is adequate with a good bumper.

Boost cushioning is popular the world over and here one can really feel the plush comfort from adidas’ technology. The cushioning is in two sections : the camouflage section and the white section. I have to say, these are the most ‘road like’ trail shoes I have run in. On hard trail they just bounce along giving a great feel for the ground. It may come as no surprise, road miles are super comfy and I’d have no hesitation to run a road training session or race in these. The outsole may not thank me though!

The outsole by Continental is superb offering great grip and feel, wet or dry, on hard trails and rocks. The outsole is not aggressive though, so forget mud!

SUMMARY

The Terrex Agravic Boa® is a really great trail shoe for those looking for great comfort, cushioning, 7mm drop and a roomy toe box. It’s the type of shoe you can slip on and spend all day in without ever thinking about foot comfort.

Stand out features :

  • The sock liner – darn it is so comfortable.
  • The Continental outsole.
  • The Boost cushioning.
  • The shoe design, particularly in the overlays that hold the foot.
  • And yes, the Boa® system really shines here. For me, it’s a turning point (pun intended) that convinces me that I would happily use these shoes and this system on a regular basis. My laces never came lose. Adjusting on the go was quick and fast – faster than any other lacing system. But importantly my foot was held secure and tight when I needed it.

The shoe is for everyday trail running and happily takes road too. It’s not a shoe for mud, but that is obvious when one looks at the outsole.

This is a great adidas shoe and I am in no doubt that shoe has benefited from feedback from the ‘elite’ adidas Terrex team. It’s an exciting time to see what else adidas have in the line-up for 2019 and 2020.
