The Vibram Wolftrack clipless sole is designed to improve traction and braking while ensuring unparalleled grip on dry or wet surfaces. The shape is optimized for easy coupling and release, and the angular knobs guarantee maximum effectiveness in terms of traction and braking. The EVA midsole reduces weight and improves shock absorption. The SLW3 closure system, the only one with a gradual release, allows a millimetric adjustment of the shoe quickly and intuitively. The upper is made of ripstop and TPU with anti-wear inserts also in TPU positioned on the toe.
