Waterproof shoe in GORE-TEX membrane specific for winter running. Structured and protective, it is suitable for Ultra Trails, Ultra Marathons and extended training sessions in the winter months. Akyra GTX is particularly enveloping, comfortable and breathable.

It adopts a very enveloping water-repellent and anti-dragging mesh upper structured on 3 layers that give from the inside out: comfort, thanks to the seamless construction, flexibility and structure thanks to the innovative MicroLite Skeleton application that follows the movement of the foot dynamically while running, protection thanks to the Flex-Guard structural applications which keep the shoe light but at the same time providing a barrier against possible abrasions when running between rocks and roots. The exceptional stability is given by the TrailCage System technology which, placed between the two layers of the upper, gives structure and enveloping integration with the lacing system.
The sole developed by the La Sportiva R&D department features the new adherent FriXion XT tread with Impact Brake System and exclusive design with Trail Rocker technology which favors the natural "external heel-internal toe" support of the foot during running.
