Jackal is a mountain running shoe for off-road running on ultra-long distances and extended training sessions on medium distances. The innovative Infinitoo technology, which provides higher energy return, is ensured by the excellent cushioning. For the lacing, the loops have been used directly on the lateral inserts of the upper: this solution allows better volume regulation during ultra-long runs when the feet tend to swell. The net mesh on the sides provides ventilation and a pleasant climate. However, the heart of the Jackal lies in the innovative unit of sole/midsole made of EVA with inner cushioning pads made of polyurethane with high energy return Infinitoo technology. The front insole increases cushioning, while the rear insole contributes to stabilisation during running. The midsole is made of compressed EVA with integrated Rock-Shield for a stable running and rock-guard effect. The outsole is made of the Frixion-Red compound with lugs with differentiated thickness as well as the "Impact-Brake-System" and longitudinal FLEX grooves that facilitate the bending of the sole along its folding lines. The lightweight and impact-resistant thermoformed toe gives lightness and protection, while the dual FriXion Red compound sole offers maximum grip and durability. A high-tech product inspired by athletes for whom running is an exploration of their own limits and themselves. Jackal: find your ultra.
