La Sportiva Jackal Shoes

Jackal is the mountain running shoe created for ultra-distance off-road races and prolonged medium-distance training thanks to the exceptional cushioning guaranteed by the innovative Infinitoo™ high-energy-return technology. Every detail, from the upper to the sole, is studied to promote foot comfort over long distances: comfortable fit and a wide last designed for use in ultra-marathons, soft and enveloping Comfort Fit elastic tongue for maximum freedom of movement, sock type to prevent the entry of stones or mud. The lacing system incorporates the eyelets directly on the side panels of the upper: a solution that facilitates the adaptation of the volume during long-distance running, in which the foot tends to swell. Lateral Net-Mesh favors ventilation and thermal comfort. The heart of Jackal is in the innovative EVA sole/midsole assembly with internal shock-absorbing inserts in polyurethane with high energy return Infinitoo™ Technology. The front element increases cushioning while the rear insert contributes to stability during the race. The midsole also integrates a high-density EVA Rock-Shield insert for a more stable ride, adding rock-guard protection. The sole is in the FriXion Red compound with studs of differentiated thickness Impact Brake System and longitudinal FLEX Grooves that favor the flexing of the sole in unison with the line of flexion of the foot. The toecap is made of lightweight thermoformed anti-shock rubber that contributes to lightness and protection, while the FriXion Red bi-compound sole ensures maximum grip and durability. A concentration of technology inspired by the one who runs in search of his own limit and the search for himself. Jackal: find your ultra.
