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 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.
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.
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.
