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.
+ Innovative dual density EVA sole / midsole package, one more cushioning and one capable of ensuring greater stability. It is equipped with Infinitoo ™ technology, two internal shock absorbing polyurethane pads with high energy return.
