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 extended training sessions. Excellent cushioning is provided by the innovative Infinitoo™ technology, which provides higher energy return. The Gore-Tex® membrane with Invisible fit technology provides maximum flexibility, waterproofing and breathability. Comfortable fit and wide fit for use in ultramarathons, elastic tongue "comfort fit", enveloping and soft, for maximum freedom of movement, internal bellows construction for protection from rocks and mud. In the lacing, the loops were used directly on the lateral inserts of the shaft: this solution allows better volume regulation during ultra-long running, when the feet tend to swell. The side Net mesh provides ventilation and comfortable climate. The heart of the Jackal lies in the innovative unit of sole/midsole in EVA with internal cushioning pads in polyurethane with high energy return Infinitoo™ technology. The frontal insert increases cushioning, while the rear insert improves stabilization during running. The midsole is made of compacted EVA with integrated Rock-Shield for a stable running and rock-guard effect. The outsole is made of Frixion-Red compound with Impact-Brake-System lugs with differentiated strengths. Impact-resistant TPU-protective toe, FriXion-red-sole with dual compound, for maximum grip and duration. A high- tech product inspired by athletes who see running as exploring their limits and themselves - even in the winter months. Jackal GTX: find your ultra.
