VJ Sport MAXx Shoe Review

I get asked a great deal what is the best shoe for trail, ultra and mountain running? Of course, there is never a definitive answer as so many variables come into play – gait, drop, persons weight, running style and so on and so on.

It comes a so secret that VJ Sport make two of the best shoes for running in the mountains, the IRock 2 (here) and the recent XTRM (here).

I thought with the XTRM that VJ had excelled themselves taking all the stunning features of the IRock2 and then adding them to the XTRM and providing a shoe that was better for running longer in the mountains.

The above two shoes were designed in collaboration with OCR and skyrunning World Champion, Jon Albon. The XTRM was specifically designed to meet Jon’s needs when running longer both time and distance.

Well, VJ and Jon have now collaborated again and come up with the MAXx.

Going back to that original question, ‘what is the best shoe for trail, ultra and mountain running?’

My answer will be now, go look at the VJ Sport MAXx first.

I have been in these shoes for a month on all sorts of terrain and they are now the only shoe I am using. VJ have nailed it once again. I don’t know how they do it…

If you like IRock2 and XTRM then the MAXx is just going to be immediately added to your shoe selection and quite simply you will then have a shoe for the following:

  • Fell and short mountain races – IRock2
  • Medium distance mountain and skyrunning – XTRM
  • Long distance mountain ultra, trail and skyrunning – MAXx

To put the above in context, Jon recently raced the 73km Transvulcania on the island of La Palma, he used the MAXx.

Everything that is perfect in the IRock2 and XTRM is replicated here in the MAXx – the only difference coming with the notable bounce and cushioning – I love these shoes!

Specs:

  • Medium last
  • Rubberized and protective toe cap
  • Rockplate for the length of the shoe
  • Kevlar breathable upper
  • 6mm drop
  • 4mm Butyl rubber outsole
  • Cushioning front 10mm and rear 16mm

Quite simply, VJ Sport make the best outsole for trail, mountain and skyrunning, no other outsole comes close to the sticky compound that VJ create. Many sponsored runners agree, and they use different brands!

The XTRM has 6mm outsole and here on the MAXx we have 4mm – this makes a logical sense to reflect the trail and ultra-objectives of the shoe. So, if you need a shoe for really muddy ground, you will be better off with the XTRM. However, if running long on trail, mountain, snow, ice, rock (wet or dry) then the MAXx is the shoe for you.

Feel when sliding the shoe on is just like the XTRM, the toe box is medium and works perfect for me. Sizing is true to size, I am a UK 9.5 and these are perfect with a thumb nail width above my gig toe. Toe box is wider than the XTRM.The upper is arguably the most durable there is without losing flexibility or breathability. Kevlar is going to outlast the outsole and several years of using VJ shoes, I have never had an upper fail or tear.

FITLOCK is just amazing as I have mentioned previously with the IRock2 and the XTRM. Here the FITLOCK is the same, it pulls in on the middle of the foot creating the most comfortable and secure feel of all shoes I have tried.

Toe box is really substantial and protective and ideal for any mountain race when collision with rocks is a high risk. The heel box is as on all previous VJ shoes, snug and secure.

The cushioning is the marked difference in the shoe, and it is noticeable immediately. I intentionally landed with my heel on some runs and the cushioning compressed beautifully and gave a lovely bounce and push in the transition phase. On road and hard trail, the shoes move along wonderfully and feel a great deal like my Nike Wildhorse (another favourite shoe). The cushioning does not lose feel for the ground though. I still have that contact and sensory perception that is really important for me when running off-road, especially if on technical terrain. Of course, there is less feel than the IRock2 and XTRM. There is more cushioning! On stoney ground, the rock plate is spot on providing that all important protection, especially important when running longer. We can all tolerate a little discomfort for an hour or two, but if running for 4, 5, 6, 7 hours or longer we need more protection and for many, more cushioning.

The great thing about the MAXx is its ability to be an everyday trail/ mountain shoe and this is a huge selling point. The MAXx will work perfectly for racing and everyday trail running, that for me is just perfect.

SUMMARY

I said I couldn’t find any faults with the XTRM and the same applies here with the MAXx. In all honesty, I think (for me) the MAXx is now my ‘go-to’ trail/ mountain shoe. The combination of elements makes it perfect. If I was a racing snake, I would line up the IRock2, XTRM and MAXx and decide on a weapon that best suits the race. But I am not, I am runner who loves to play in the mountains and the MAXx is just perfect for 1-hour runs or full-day outings. I think it’s worth noting that races such as the Dragons Back, Cape Wrath Ultra or say, Ultra Tour Monte Rosa when runners must spend long and multiple days in the mountains, the MAXx is perfect for this. This shoe is a complete winner and it is going to take a truly amazing shoe to come along and make me choose it for my mountain/ trail runs in the future. Yes, this VJ Sport MAXx is that good!

VJ XTRM Shoe Review – VJ Sport

Last year I finally got my hands on a pair of VJ Sport IRock 2 (HERE). I was blown away by pretty much everything about the shoes. The upper, the way they held one’s foot, the durability of the materials used, and the outsole was just incredible – the most amazing grip. The only reservation that I had, was how long I could run in these shoes… They are pretty minimal and although cushioned, the cushioning for me would probably only take me to 3-4 hours of running.

OCR World Champion and Skyrunner World Series Champion, Jonathan Albon, agreed. In some of the longer races, Trofeo Kima for example where the terrain is hard, rocky, muddy, has snow, maybe the odd glacier thrown in and when the male winning time is over 6-hours, although the IRock 2 was perfect on grip, the cushioning made a really long run like this tiring for the feet.

With Jon’s feedback, VJ Sport went back to the drawing board, took all the best elements of the IRock 2 and created a new shoe:

VJ XTRM.

The king is dead, long live the king!

Let me just say in simple terms everything that was brilliant in the IRock 2 has been transferred to the new VJ XTRM and what VJ Sport have done, in my opinion, they have created the most perfect mountain running shoe for when the trails are demanding, rocky and throwing all sorts of variables at the runner.

So, what is new in the VJ XTRM.

  • Two new cushioning units have been added to the front and rear.
  • A full-length RockPlate.
  • A medium last.
  • A little extra room in the toe box.
  • New Fitlock.

As I mentioned, much of the IRock 2 crosses over. For example, the outsole is the amazing Butyl Rubber which for me offers the best grip I have encountered on any mountain shoe. The outsole studs are 6mm which offers a good compromise between grip on muddy/ wet trails and excellent grip on smooth and easy single-track.

At 250g for a standard UK8, the shoe is light and 4mm drop sits in a comfortable middle ground for the zero drop fanatics and those who like a more comfortable and relaxed 8mm drop.

Kevlar and Polyester make the upper and the IRock 2 has been the most durable shoe I have ever used, so, I don’t anticipate the VJ XTRM to be any different. There is also Fiberclass stability control.

THE SHOE

Slipping one’s foot into the VJ XTRM one immediately feels the snug and precision fit. However, the slightly wider toe box is noticeable. Don’t get me wrong here, this is not a wide and spacious toe box, so, if that is what you personally need, this may well be not the shoe for you. Please remember though that this is a specific mountain/ skyrunning shoe that will be used on technical mountainous terrain, so, a shoe for this type of running should be precision.

Pulling the laces tight, the FITLOCK takes hold and provides the most secure and comfortable hold of my foot. It is the best I have tried, no question. The laces are excellent, they pull tight and stay tight.

The upper is a mix of materials and is extremely durable. Although it is too early to comment on longevity of the VJ XTRM upper, the materials and comparisons with the IRock 2 are very close. My IRock 2 have been through everything and are still going strong. The heel box has minimal padding but holds the foot secure and is extremely comfortable. The toe box is well protected and ideal for mountain terrain.

The colours of the upper are a little bright. They wouldn’t be my choice, I certainly loved the red & black combo of the IRock 2, but colours are just colours and after a good muddy run, the colours soon become muted.

Like the IRock 2, the VJ XTRM looks heavy, pick them up and you realise they are not, they are super-light!

The bottom of the shoe is what helps VJ Sport stand out amongst the competition and why they have such a following. The Butyl Rubber they use is the best outsole I have ever tested and on rock terrain, dry or wet, they are the most reassuring footwear ever! The 6mm studs are the same as on the IRock 2 and this is significant, the IRock 2 provided the best grip ever, so, to see this transferred over to the XTRM is superb.

IN USE

The IRock 2 last-year was the best mountain shoe I have ever used. This has now been replaced by the VJ XTRM and for me, moving forward, I would always purchase the VJ XTRM and not the IRock 2. For me, VJ Sport may well have killed the IRock 2 because the VJ XTRM is so good.

 sport

WHY?

To all intents and purposes, the IRock 2 and VJ XTRM are very similar shoes. One difference is 6mm drop for the IRock 2 and 4mm drop for the VJ XTRM, this may be a decision maker for some? However, the new additions to the VJ XTRM just make it a much more versatile shoe without compromising what made the IRock 2 great, no, superb!

  1. The added cushioning doesn’t compromise feel for the ground, control, stability for faster shorter mountain running but what it does allow is more cushioning and comfort for longer runs.
  2. The RockPlate is a no brainier, it is added protection and added comfort for little to no additional weight.
  3. The new Fitlock holds the foot as well, if not better than the Fitlock on the IRock 2.
  4. The toe box has been widened to allow for a little more room and toe splay when running longer but not at the compromise of precision and feel.
  5. The upper is as the IRock 2 with Kevlar and outstanding durability.
  6. The outsole is the same, 6mm studs in the amazing Butyl Rubber.

The additions make the VJ XTRM the perfect all-round mountain shoe be that for short or long outings. Whereas, the IRock 2 was a shoe that I personally would not want to be out in for much longer than 4-hours.

SUMMARY

This is the best mountain running shoe I have ever used. For skyrunning, it is THE perfect shoe and for me, all other shoes that I test for that intended use will be compared to the VJ XTRM. Jonathan Albon’s influence can be felt in this shoe and I am sure his feedback with VJ Sport has been paramount in retaining all that was brilliant in the IRock 2 and then tweaking it to add what Jonathan and many other runners wanted; more cushioning, a RockPlate and a slightly wider toe box.

I personally am unable to find any negatives.

Obviously, the Butyl Rubber outsole works so well because it is soft and grippy, so, if you start running on roads and pavements, be aware, the outsole won’t last.

But the VJ XTRM is a formula 1 shoe and not a Ford Escort or similar. Maybe the VJ XTRM should make an appearance for those special runs or races?

However, if you are like me, I think the shoes are so awesome that if I am going to run anything technical, wet or dry, I want these shoes on my feet.

IROCK2 by VJ Sport – Shoe Review

Imagine a scene:

A man enters an elevator, he pulls the cage metal door across and as it clicks into place, his right hand reaches for the buttons to his left. ‘Lower Basement’ is pressed.

As the lift moves, music starts in the background; a lone guitar.

dundedun dun dun dun dundedun dun dun dun dundedun dun dun dun dundedun dun dun dun deDON Do do do
Badap ba daa ba da daa ba daa da deda daa Badap ba daa ba da daa ba daa da deda daa

The lift stops, the gate is pulled open and the man walks into a grey room illuminated by dappled spotlights. Ahead, a man in a white jacket, is crooked over a table with his back turned.

“Argh, 007 you are here, finally! Now listen up. This is the new IROCK2 by VJ Sport. It has Fitlock that ensures a sure and precise fit around the arch and instep of the foot for secure constant changes of direction. The outsole is made of Butyl rubber with an aggressive pattern, it will grip anything in the wet and dry!”

“And the upper Q?” Our man asks.

“007, let me do the talking… The upper is made of Kevlar, it’s stronger than steel, lightweight and extremely durable. Toe box and the heel box is plush, secure and protects from the toughest terrain. Cushioning is provided by KvamO and Duotech. These shoes are designed for fast, light and agile mountain running on any terrain – any questions?”

“When can I use them Q?”

“Have you not been listening Bond? You can use them on the gnarliest, muddiest, wettest, driest, most technical terrain imaginable and they will give you the advantage over the competition… Now go run!”

If James Bond was a mountain runner, he’d be using the IROCK2 by VJ Sport

*****

This review comes in two versions:

Version 1.

The IROCK2 by VJ Sport is the best mountain running shoe for any terrain with superior grip in the wet and dry on the rockiest, gnarliest, muddiest terrain imaginable in a moderately cushioned, 6mm drop, lightweight neutral shoe. It’s the best shoe ever – go buy it!

Version 2.

Read on.

VJ was found in 1981 and has been the secret weapon of Orienteers for many, many years. Ask anyone in the know, affiliated with a brand or not, out of choice, if they could, they would use IROCK when the need for grip on wet and dry surfaces is essential.

I was first introduced to the brand several years ago whilst working on the Tromso SkyRace. I saw the ‘locals’ using them and when out on the trails, mountains that had a mix of rocks, snow and ice, I continually noticed they had more grip than myself. This was confirmed when Jon Albon won Tromso race using IROCK ahead of the ‘almost’ unbeatable Luis Alberto Hernando.

I took note!

The shoe range can be viewed HERE and over the year’s VJ Sport have added and tweaked the line of shoes to 12 models, varying from a very specific Orienteering shoe with metal spikes (midstud) to a kid’s shoe!

Key Features of the IROCK2:

FITLOCK ensures that the fit is snug and holds the foot in place, essential when running on technical and challenging trails when a change of direction happens in a fraction of second. You don’t want a sloppy shoe. FITLOCK supports the arch of the foot and protects from the terrain.
SUPERIOR CONTACT OUTSOLE is made from sticky butyl rubber with an aggressive grip. It has superior grip in wet and dry conditions and lugs are aggressive to gain traction in mud. They are also spaced out to help release mud from the sole so that you don’t get clogged up and lose traction.
Schoeller® – Keprotec® KEVLAR upper is bullet proof and stronger than steel. It is pretty much tear resistant with comfort. The chances of the uppers failing is almost non-existent. The upper also has reinforced sections, the toe box and heel cup protect the foot from the most demanding terrain and to keep the foot secure.
KvamO offers cushioning, torsion support and a shaped insole.
DUOTECH is used on the inner side of the shoe, contrasting against the KvamO. The Duotech is higher density foam which makes for a more durable shoe.

IROCK2 was Jon Albon’s shoe of choice for the 2017 season – He is a multiple OCR World Champion and two-time Skyrunner World Series Champion for the Extreme classification.

OUT OF THE BOX

Red and black, always works for shoe colours and I feel and I am instantly attracted to the IROCK2. However, they don’t look like run shoes… almost a cross between a football boot and a shoe for MTB. They look heavy!

I lift one up. They are not heavy… It almost comes as a surprise. Immediate first impression is how robust the shoe looks. The heel box is reinforced, the Fitlock looks aggressive and secure, the Kevlar material looks like it is interwoven with strands of steel and the toe box reinforced with a bumper. Turning the shoe over, soft black butyl rubber covers the outsole and a mass of aggressive studs immediately confirm that the IROCK2 means business as far as grip is concerned.

Lacing is very secure and the tongue is reinforced and made of a very durable flexible but hard material. I am surprised to find that the IROCK2 does not have a gusseted tongue or sock liner fit. I feel disappointed! It’s no secret if you read my shoe reviews that this is by far my favourite method of shoe fit. The toe box looks really narrow – I expected narrow as this is a precision shoe, however, they look narrower than expected.

All-in-all, I am impressed. Great looks, solid build, aggressive outsole but I have concerns on the toe box and lack of sock liner/ gusseted tongue.

IN USE

It’s important to remember here that the IROCK2 is not a jack of all trades, it’s not a trail shoe, it’s not hybrid shoe, it’s not a shoe for the road – it is an out-and-out specific fell/ mountain running shoe and as such, you should and must keep this in mind if considering if the shoe is for you!

The easiest way to explain this is by looking at say, Formula 1. You wouldn’t go to Monaco Grand Prix and race in a MPV car, a saloon car or a bus, you’d have a very specific vehicle, low to the ground with incredible speed and awesome agility with incredible grip. The IROCK2 is the Formula 1 for fell and mountain running.

I loosen the laces and slide my foot in. I am immediately surprised that the toe box is deceptively more spacious than anticipated. Almost Tardis like. Don’t get me wrong here, they are not spacious that would allow ones toes to splay. The fit is secure but not overly narrow, however, if you have Hobbit like feet, the IROCK2 is not going to be for you! It is normal in fell/ mountain running shoes that a ‘precision’ fit is required as this provides security and precision when running, exactly what you need when on demanding and challenging terrain.

As I pull the laces tight, I am immediately surprised how well the tongue fits to my foot and the lack of a sock liner or gusseted tongue soon becomes no issue. The Fitlock steps in and I have to say that this is one of THE secret weapons of the shoe. You immediately feel the support and security this system brings as I tighten and adjust the laces.

The reinforced heel box adds to this security and once laced up and adjusted I soon realize that the IROCK2 has incredible fit and security – and I haven’t even run in them yet!

As I walk around my apartment, the wooden floor provides a solid surface, I feel the grip of the Butyl outsole take hold and with each lift of my foot, the shoes make a sound a little like when separating two strips of Velcro. These shoes seriously grip.

Orienteering, fell and outright mountain shoes rarely have a great deal of cushioning as the need to be low and feel the ground is essential. The IROCK2 has cushioning and it is noticeable without compromising feel, importantly there is also a rock plate for protection. Therefore, this shoe certainly provides an option for longer races, be that in distance or time. How long or how far depends on the runner, but I would certainly consider this shoe for 6-8 hour mountain jaunts. You also must remember that if running on soft and muddy ground, much of the cushioning actually comes from the ground beneath ones feet. Rocky and hard trails are a different story.

ON THE TRAILS

I always start my test runs with a section of road and the IROCK2 keeps me honest wanting to land fore to mid foot. I can hear and feel the grip on the road and I am surprised at the level of comfort and cushioning for such an aggressive shoe. I set my mind at ease knowing that the IROCK2 can handle road sections should they crop up in a race or training. Note though, the outsole won’t thank you for this and one can expect it to wear quicker if you throw too much tarmac at them.

6mm drop works well and although 8mm is normally preferable (for me) it is appropriate that a shoe of this nature has a lower drop keeping you connected to the ground. The fit is neutral but Fitlock really does provide support (in a good way) to ones arch. Fit is true to size.

Back on the tail, a 3-mile section of single track flies by as the shoes happily eat up the miles switching between hard and dry sections and soft, wet, muddy sections don’t compromise the grip.

Off track and the IROCK2 start to feel seriously at home. I am now on open fell that is rutted. I am constantly changing direction and this is when I feel the Fitlock and heel box working together. For me, it’s the best feel and most secure of any mountain running shoe I have used. No question!

The outsole is gripping everything.

On a vertical wall of grass and mud, I am on my toes and the shoes just dig in and keep me going forward with no wasted energy through slipping.

I hit an extremely muddy section. It’s like a brown river. Constant rain has made it into a brown lake and as I run through it, the height passes my ankle. Once again, I feel the shoes pushing through the soft upper layers to find traction below. Grip is found and I am able to move on with more security than any other shoe used. The closest comparison coming with an inov-8 Mudclaw.

It’s on rocks, wet or dry, that the IROCK2 becomes outstanding. I have had mountain shoes in the past that have handled the mud only to find that rock, and in particular, wet rock grip is compromised. The IROCK2 stand out as the best in its class with unmatched grip and control.

The run continues on and as the terrain constantly changes I am finding that the IROCK2’s are handling everything but it is the overall package of the shoe that is impressing me and no one stand out feature.

It is the combination of durability, fit, cushioning, precision and unmatched grip that is making me realize that the IROCK2 is the best fell/ mountain shoe I have used.

LONG TERM

Mud, rock, fell in wet or dry conditions, the IROCK2 is the best I have used. I have now put just under 200-miles on them on a whole multitude of scenarios and without doubt, this shoe stands out. It’s the overall package as mentioned above that make them so special and in comparison to other brands, the Kevlar uppers show no sign of use.

It’s easy to get carried away when writing about a shoe like this but so often I have had a mountain shoe that does one thing really well only to find that it is compromised in another use. Not so with the IROCK2.

It is the most complete mountain shoe I have used for its specific use.

SUMMARY

VJ Sport was created in 1981 and although I first became aware of these shoes in 2014, I have to say that I really have a feel of ‘FOMO!’ – Fear Of Missing Out.

Orienteers and obstacle racers will be reading this review and saying – ‘Yep, yep and yep!’

They will be asking the question, ‘What took you so long?’

They are correct, what did take me so long?

VJ Sport have been making secret weapons for the orienteering world for so many years but now the secret is out!

I have already heard many a Skyrunner talking about the original IROCK and now the IROCK2 moves things up a notch and quite simply:

This is the best fell/ mountain running shoe I have ever used.

CONCLUSION

It’s a glowing review, no doubt.

There are so many PROS to the shoe that I feel I must try and reign myself in and find some CONS, so, here goes:

I have been trying to get a pair of IROCK’s for sometime, it took me 18-months to finally get a pair. They are not easy to come across! However, see at the bottom of this review as we have an offer.
The IROCK2 is a fine tuned piece of kit designed to excel with a very specific use. This is not an everyday shoe (unless you are always on fells/ mountains) that you use on road and smooth trail.
In reference to point 2, you will need other run shoes for those ‘normal’ runs when the IROCK’s are not required.
The IROCK2 has cushioning but it is NOT a ‘cushioned’ shoe and it shouldn’t be. Some cushioning is good but anymore and this shoe would lose the feel and control that makes it so great.
The fit is precision, again, as it should be for a shoe with such specific use. Worth keeping in mind for the Hobbits out there!

FINALLY

Skyrunning? Fell running? Mountain running? Running in the wet, mud, on dry rocks and wet rocks?

Need a 6mm drop, neutral and moderately cushioned shoe?

Look no further than the IROCK2 by VJ Sport.

OFFER

*Please note, I have no affiliation or working relationship with the following, this is purely an offer to help those who may be interested in the IROCK2 to purchase a pair.
