La Sportiva Jackal GTX
Jackal GTX is the winter running shoe dedicated to off-road running during winter months over ultra distances and long workouts thanks to the exceptional cushioning guaranteed by the innovative Infinitoo™ high energy return technology. The Gore-Tex® membrane with Invisible fit technology guarantees maximum flexibility, waterproofness and breathability. A comfortable, wide fit designed for use in ultra-marathons, wraparound, stretch tongue, for maximum freedom of movement, internal gusset construction for protection against stones and mud. The lacing sees the loops incorporated directly into the side panels of the uppers: a solution that facilitates volume adaptation during long distance runs in which the foot tends to enlarge. The lateral Net-Mesh favours ventilation and climate comfort. The heart of Jackal is the innovative EVA sole/midsole package with internal cushioning in high energy return polyrethane Infinitoo™ Technology. The front element increases the cushioning, the rear insert contributes to the stabilization of the run. The midsole also incorporates a high-density EVA Rock-Shield insert for a more stable run and rock-guard effect. The tread uses the Frixion Red Impact Brake system with differentiated lugs. Shock resistant TPU toecap, FriXion Red dual-compound sole, for maximum grip and durability. A concentration of technology inspired by those who run in search of their own limits and in search of themselves, even in the winter months. Jackal GTX: find your ultra.
