La Sportiva Jackal GTX Shoes Men black/yellow

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.
