La Sportiva Jackal

Jackal, find your ultra

A mountain running shoe ideal for off-road running over ultra distances and workouts on medium distances thanks to the exceptional cushioning guaranteed by the innovative Infinitoo™ high energy return technology.

Every detail, from the uppers to the sole, is designed to enhance the comfort of the foot over long distances: wide, comfortable fit designed for use in ultra-marathons, comfort fit, enveloping and soft elastic tongue for maximum freedom of movement with internal bellows to protect against stones and mud. The lacing sees the loops incorporated directly into the side panels of the uppers: a solution that facilitates the adaptation of volumes during long distance runs in which the foot tends to swell. The lateral Net-Mesh promotes ventilation and climate comfort.
The heart of Jackal, however, lies in the innovative EVA sole/midsole package with internal cushioning pads in high Energy return polyurethane 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 for a more stable run with rock-guard effect. The Frixion Red tread with differentiated Impact Brake System lugs and longitudinal FLEX grooves enhances the flex of the sole along the fold lines. The lightweight, shock-resistant, thermo-shaped toecap contributes to the overall lightness and protection of the shoe while the dual compound FriXion Red sole guarantees maximum grip and durability. A concentration of technology inspired by those who run in search of their own limits and in search of themselves.

Impact Brake System
The innovative system is applied to the sole to absorb negative ground impact, help traction and improve grip downhill.
Created and developed by the R&D department at La Sportiva, it offers real advantages during racing by reducing negative ground impact. The unique position of the lugs allows as many of them as possible to come into contact with the ground, for maximum impact absorption.
