X Tension

This active midsole concept adapts to the changing footshape while loading and unloading bodyweight to the forefoot area, effectively storing and releasing power. The tensioned rubber enhances toe power providing a direct connection
among the front edge of the sole, the upper closure (lacing, Velcro®, elastic band) and heel area. The X-TENSION™ system supports the arch- and forefoot area without taking away sensitivity like stiff midsoles. X-TENSION™ is combined with half soles.
