LA SPORTIVA Jackal GTX

Jackal GTX is a winter running shoe for off-road running in the winter months on ultra-long distances and for extensive training units. 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. For the lacing, the loops were used directly on the side inserts of the shaft: this solution enables better volume regulation during ultra-long runs, when the feet tend to swell.

The side net mesh ensures ventilation and a pleasant climate. 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 insert increases cushioning, the rear insert improves stabilization when running. The midsole is made of compressed EVA with an integrated rock shield for stable walking and a rock-guard effect.

The outsole is made of a Frixion Red mixture with Impact Brake System studs with differentiated strengths. Shock-resistant TPU-protective tip, FriXion-Red sole with double compound, for maximum grip and durability. A high-tech product that was inspired by athletes who see running as exploring their own limits and themselves - even in the winter months. '
