The  La Sportiva Frixion®  stem arose from the desire to create outsoles with increased parametres of hold and durability. This will decline on the basis of types of use and terrain.
The frixion range  consists of four different types of rubber.

A number of La Sportiva Mountain Running® shoes use EVA injected midsoles which differ from the standard compression molded EVA midsoles for a high degree of cushioning and a better elasticity o fthe fabric.
These features assist “push off” during the propulsion phase while running, making these models ideal for use on offroad trails. Furthermore, EVA injected midsoles drastically reduce the“squash” effect of the EVA over time, allowing the product to maintain the same characteristics and high performance for its entire duration.
Some La Sportiva models use standard compression molded EVA midsoles for the durability and reactivity on soft ground where the need for shock absorption is reduced.

The Mountain Running models from SS2014 collection  adopt the exclusive La Sportiva insoles by Ortholite, with 2 different thickness. Both models are available in men and women version and differs for the materials’ densities.

• Breathable for a cooler foot.
• The unique open cell structure creates a moisture management system.
• Long term cushioning: insole will retain over 95% of its thickness over time and won’t flatten out.
• Anti-microbial agents and washable properties for a more igienic shoe.

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.
