The La Sportiva Women's Cyclon Trail Running Shoes are built for sky races and off-road racing on technical terrain at medium distances. The result of research and development between La Sportiva and BOA™, this shoe guarantees stability, precision and a perfect fit thanks to the Dynamic Cage™ closure system with integrated BOA™ Fit System. This works in synergy with 3 different elements of the upper for perfect binding and stability of the foot for a safe and precise downhill run. The heart of the lacing system is the internal Dynamic Flap ™ that wraps the shoe and allows dynamic adjustment of the tension by acting directly on the BOA™ Fit System with a one-hand movement. The protective TPU toecap and the multi-layer, thermo-adhesive side panel provide additional structure and impact protection. The mud-ground tread, ideal for use on soft and muddy ground, is in ultra-grippy La Sportiva FriXion™ White compound and provides the possibility of integrating AT Grip Spike nails in case of use on icy ground. The double-density EVA midsole with stabilizer insert contributes to the overall stability of the shoe and contains weight.
