Welcome to the future! The La Sportiva Cyklon feels like a glimpse into the crystal ball of skyrunning shoes. A brain child collaboration between La Sportiva and BOA, the Cyklon is an impressive end result that provides everything you need for skyraces and off road running. It balances precision, stability, and on-trail feel. By incorporating a BOA into their Dynamic Cage closure system, you’re able to literally dial in your exact fit by tweaking the amount of volume. The Spyral Tongue EVO ensures that the BOA’s tightening is homogenous and doesn’t unevenly apply pressure in certain spots. The rest of the upper is highly breathable, abrasion-resistant 4-way stretch mesh for ultimate comfort. The outsole features Frixion XF 2.0 Mudguard rubber which offers a sticky grip on any terrain, but especially great on soft trails. Other features, such as protective toe cap and TPU stabilizing inserts, round out the Cyklon. You don’t need a fortune teller to inform you that this shoe is fully capable and ready to give you a race day boost.

  • BOA with Dynamic Cage closure system guarantees a perfect, comfortable race fit.
  • Spyral Tongue EVO disperses pressure to prevent any bothersome spots.
  • Multi-layer side panels and TPU inserts increase stability and protection.
  • Highly breathable, abrasion-resistant 4-way stretch mesh upper for ultimate comfort.
  • Frixion XF 2.0 Mudguard rubber outsole grips on all sorts of technical terrain.

*For proper fit, we suggest sizing up one half US size.

BLUF: Would recommend this shoe to my "friends" (in the same way I recommend huge suffer-fests to them) but expect it to fail at a lower mileage than a laced shoe.

Recent purchase with about 50mi. use. I like to mountain run, so rocky and steep constitutes maybe 40 of these miles and probably 80% overall of what these shoes will do. These are replacing Sportiva TX3 and Sportiva TX Guide Pro shoes (decided an actual running shoe might feel better), so this is the basis of comparison.

Pros:
- Lightweight. My feet feel so fast and nimble.
- Grip. 130% on trails and 80% on pure rock.
- Gaiter! It really works and is comfortable. Only dust gets in.
- Comfort. Turns out a running shoe ventilates, cushions, and supports better than an approach shoe.

Cons:
- Complexity. Overall there aren't too many failure points on this shoe (high wear zones seem nicely considered) but, of course, the BOA is there. While I do enjoy "dialing" the fit (which is a little faster and precise than fussing with laces), I really am nervous about its lifespan. I have already sheared the BOA tower off the shoe (it snaps back on, seemingly undamaged). The cable and eyelets seem feeble, as well. I'm sure this feature will be the root-cause failure of the shoe and is the reason for the 4/5 star review (I can already envision jogging down from the Wes Slabs or Superior with an un-tensioned broken shoe).

Overall, a better shoe for what I enjoy doing. It will be 5/5 if its robustness is proven. I will come back and update at the 300 mile-post.

Hey Jarrod, thanks so much for the detailed review. We would love to hear an update when you get to the 300-mile range on the shoes as well.

Sorry to hear about the initial failure with the BOA dial, but glad you got it sorted out by popping it back in. After having fairly detailed talks with BOA and La Sportiva, it seems like while the BOA dial may be the weak point in the shoe the actual dial is designed to pop out instead of breaking. While it is obviously possible to have a catastrophic failure of the dial, it was very reassuring the amount of testing that goes into the dial and is meant to outlast the intended life of the shoe by a large margin.

Question from Alex
 
Hi Skimo/SkyRun, I usually wear a 44 in the Sportiva Ultra Raptor and am interested in the new Cyklon. Any insight on sizing?

Answer from Zak M
 
Hey Alex, I would say to just stick with the same size that you have for the Ultra Raptor. Let us know if you have any more questions!

Question from TSB
 
Équipe Course du Ciel,
Are you planning on bringing in any Cyklons in a size 46.5-47? I see on La Spo's site that they will be making those sizes for us big-feet.

Semi-related, where does the Frixion XF outsole rubber fall in terms of sticky-ness and durometer relative to the rest of the Frixion line? I'm guessing b/w the Red and the Green?

Danke schein!

Hey Scott, feel free to shoot us an email at help@skimo.co and we could look into what La Sportiva will have available! To answer your second question Frixion XF Rubber is the stickiest compound they use for their running shoes. Also based on Spotivas chart it falls short on durability between both Frixion AT 2.0 (blue) and Frixion XT 2.0 (red). So in short Frixion XF has excellent grip and stickiness but will be slightly less durable than other shoes in La Sportiva's line.

Question from Kyle
 
How does the cyklon compare to the mutant in terms of fit and security on technical trails? Will the cyklon eventually replace/displace the mutant?
4/13/2021
Answer from Zak M
 
Hey Kyle, since we haven't gotten a chance to fully try out the new Cyklon it's hard to say exactly how the fit compares to the Mutant. We do know that La Sportiva states that the fit should be slightly narrower than the Mutants medium/wide toe box though. With the BOA® lacing system and aggressive lug pattern if you are looking for a super technical and precise shoe then the new Cyklon should fit the bill quite nicely. For longer days with a mixture of both technical and tricky terrain combined with lots of miles I would tend to lean a bit more towards the Mutant for its superior cushion.
