ORTHOLITE Hybrid MR E

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.

• 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.

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.

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.
