La Sportiva Jackal GTX Running Shoes - Black/Yellow

The winter running shoe in Gore-Tex® membrane with Invisible fit technology dedicated to off-road running in the winter months over ultra distances and long workouts thanks to the exceptional cushioning guaranteed by the innnovative high energy return Infinitoo™ Technology midsole.

Jackal GTX is a winter running shoe for off-road running in the winter months over ultra-long distances and for extended training sessions. The excellent cushioning is guaranteed by the innovative Infinitoo™ technology, which provides higher energy return. The Gore-Tex membrane with Invisible-Fit technology provides maximum flexibility, waterproofness and breathability. Comfort fit and wide fit for ultra marathon use, elastic tongue "comfort fit", enveloping and soft, for maximum freedom of movement, inner bellows construction for protection against stones and mud. The lacing system uses loops directly on the side inserts of the shaft: this solution allows better volume regulation during ultra-long runs when the feet tend to swell. The lateral net mesh provides ventilation and a pleasant climate. At the heart of the Jackal lies the innovative EVA sole/midsole unit with internal polyurethane cushioning pads with high energy return Infinitoo™ technology. The front insert increases cushioning, the rear insert improves stabilization while running. The midsole is made of compressed EVA with integrated rock shield for stable walking and rock-guard effect. The outsole is made of Frixion Red compound with Impact Brake System studs with differentiated strengths. Impact-resistant TPU protective toe, FriXion Red sole with dual compound for maximum grip and durability. A high-tech product inspired by athletes who see running as an exploration of their own limits and of themselves - even in the winter months. Jackal GTX: find your ultra.
