The La Sportiva Cyklon is a precision running shoe designed for medium-distance skyraces and off-road racing across technical terrain.

The Cyklon was conceived out of joint research and development between La Sportiva and BOA™, and it's a product that guarantees stability, precision, and a perfect fit thanks to the new Dynamic Cage™ operated by the BOA™ Fit System, which works in tandem with three separate upper elements for perfect binding and stabilisation of the foot, so you can attack those hill descents with confidence. The internal Dynamic Flap TM wraps the foot and is enabled instantly and precisely through the BOA® Fit System with one effortless hand movement. The elasticated cuff around the heel is super comfy and keeps out any unwanted stones. Featuring a TPU protective toecap and a multi-layer, thermo-adhesive side panel provides additional structure and impact protection. Thanks to deep tread, ultra-grippy La Sportiva FriXion™ White compound and the possibility of integrating AT Grip Spike nails, the Cyklon is more than comfortable handling wet-muddy or icy ground. Cyklon: float like a butterfly, run like the wind.

 Features

• Ultra-grip FriXion™ White compound sole with mud-ground tread for use on soft and muddy terrains.
• Spyral Tongue™ Evo: comfortably wrapping tongue construction with integrated heel-gaiter, ensuring a precise fit and no open spaces around the ankle: prevents the entry of outside’s elements and dynamically follows the runner’s movements.
• Lacing taking full advantage based on the BOA™ Fit System for perfect and immediate volume adjustment with one-hand movement.
• Dynamic Cage ™ construction: the BOA™ Fit System works in synergy with 3 different elements of the upper for the perfect fit and stability of the foot for a safe and precise downhill run.
