Jackal GTX is a winter running shoe for off-road running in the winter months over ultra-long distances and for extensive training sessions. The excellent cushioning is guaranteed by the innovative Infinitoo technology, which ensures higher energy return. The GORE-TEX membrane with Invisible Fit technology ensures maximum flexibility, waterproofness and breathability. Comfortable fit and wide fit for use in ultramarathons, elastic tongue "comfort fit", enveloping and soft for maximum freedom of movement, inner bellows construction for protection against stones and mud. As for the lacing, the loops have been placed directly on the lateral inserts of the upper: this solution allows better volume regulation during ultra-long runs when feet tend to swell. The side net mesh ensures ventilation and a pleasant climate. The heart of the Jackal lies in the innovative EVA sole/midsole unit with internal cushioning pads made of high-energy-return polyurethane Infinitoo-Technology. The front insert increases cushioning, the rear insert improves stabilization while running. The midsole is made of compressed EVA with an integrated Rock-Shield for a stable run and a rock-guard effect.
