Gore Tex model created for winter use off-road and over long distances, for ultra marathon competitions and endurance training sessions.
The uppers are made from abrasion resistant, breathable, water repellent mesh and the lining uses the Gore-Tex Extended Comfort membrane to guarantee water resistance and breathability.
The integrated lacing system uses a webbing stitched to the inner stretch fabric while the high frequency reinforcements remain on the external mesh fabric: this allows for an optimal distribution of foot tension and keeps the foot in check without compromising overall comfort. Ultra Raptor GTX brings together the advantages, in terms of performance, of a snug fit construction, to the superior comfort levels of wide fit models. The result is a product that can be worn for many consecutive hours and for endurance on any type of off road terrain both in the winter or in conditions of extreme humidity, thanks to the Gore Tex water proof lining. La Sportiva FriXion XF Super sticky sole.
Gore-Tex Extended Comfort
This membrane is designed for indoor and outdoor use in temperate and warmer conditions or for a higher level of activity. Shoes with Gore-Tex Extended Comfort Technology are durably waterproof with optimized breathability. Thanks to their non-insulated construction, they are the ideal solution for people who appreciate excellent climate comfort and heat dissipation.
Versatile sole for use on any type of ground: stone, gravel, grass, moss, mud. Optimal for running in very humid conditions on bare ground; uses Impact Brake System technology.
Super Sticky - Super grippy mixture, leaves no lines and is very durable. Ideal for high-performance mountain running shoes and indoor climbing shoes.
Eva - Injected
The injected sole has high damping properties and elasticity of the material. These properties support the forward footprint during running, making these models particularly suitable for off-road trails. Injected EVA midsole reduces midsole compression, which can occur as the shoe life progresses, allowing the material to maintain the same performance characteristics.
Impact Brake System
Innovative system on the sole to absorb the impact, also helps during ascent and supports braking. Designed and developed at La Sportiva's research and development centre, it offers real advantages during running: it minimises the negative effect of impact with the ground. Due to the special arrangement of the pimples, some of them come into contact with the surface beforehand, thus softening the impact of the shoe profile.
