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.

• 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
