La Sportiva Cyklon

La Sportiva Cyklon review: what runners say

Fit

Tends to run narrow, especially in the toe box — a common trait across La Sportiva's European models. The BOA system with dynamic cage delivers precise midfoot lockdown, but several runners report that over-tightening the dial shifts the forefoot material and causes toe-box contact.

Feel

Firm, responsive ride: the dual-density EVA midsole with high durometer provides rock protection without softness underfoot. Breaks in slightly after 50–100 km, but remains a direct-feeling shoe with pronounced ground contact throughout.

Durability

Midsole projected to exceed 1,000 km; Frixion White 2.0 outsole with 7 mm lugs built for technical terrain. Potential weak point: the BOA dial, which is difficult to replace if damaged on rock impact.

Best for

Mountain running shoe for technical, muddy, and rocky terrain at mid-to-long distances. Well suited for mountain training and races on aggressive courses; not recommended as an ultra shoe on dry, rocky terrain due to an overly firm ride at extreme distances.

Weak points

BOA lockdown not yet sufficient to hold the heel on descents: the foot slides forward and toes press into the upper. Weight (315–330 g) is considered high for runners looking for a fast race shoe.
