The Akyra is suitable for endurance trails, such as Ultra trails and ultramarathons. Particularly comfortable and protective, it is a shoe designed for extended use on off-road terrain. It uses a snug upper, structured in 3 layers, which provides, from inside to outside: comfort thanks to the innovative MicroLite Skeleton and a fit that follows the movement of the foot in a dynamic way while running. Excellent stability is provided by the TrailCage system, a technology placed between the two layers that provides structure and comfort. The outsole was developed by the La Sportiva R&D department and uses the Frixion XT tread with a braking system and the exclusive design with Trail Rocker technology that promotes foot support while running.
