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.

OrthoLite® Hybrid
The Mountain Running® models use the exclusive eco-friendly La Sportiva insoles by OrthoLite® Hybrid, made using 20 % recycled material from the production process. These insoles are designed for both men’s and women’s feet and the thicknesses and materials differ to suit the weight of the average user.
- Eco-friendly and washable: they contain recycled rubber and are machine-washable.
- Maximum wearing comfort thanks to the insole ventilation and the highly breathable PU foam cells: the foot is always dry and kept at the perfect temperature.
- They facilitate the wicking of sweat thus keeping the foot dry.
- Enhanced durability thanks to the anti-compression technology which keeps material compression down to less than 5 % over time.
High Volume
- Comfortable shoe, ideal for training and long distance running.
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.
Goretex
The advantages of Gore-tex invisible fit:
TRUE FIT
- The unique, flexible construction reduces weight and creates fewer pressure points, and an extremely comfortable fit and feel, so you can keep going - and going.
DURABLY WATERPROOF
- Reliable waterproof protection means your feet stay dry, from summer showers to icy winter puddles. Perfect for short jogs or long-distance races.
VERY BREATHABLE
- Moisture vapor from sweat can escape easily, so you stay comfortable-even when you are going hard.
- The membrane is invisibly integrated into the shoe, the lightweight construction is designed to disappear.
INFINITOO
- Exclusive technology that absorbs the negative impact with the ground and guarantees a never seen before energy return. The Infinitoo™ midsole mantains its original stretch features unaltered over time.
