Climbing shoes La Sportiva Theory - yellow

Engineered with the revolutionary No-Edge Technology and a high-tension P3 Permanent Power Platform, the La Sportiva Theory delivers uncompromising precision on steep rock. The Vibram XS Grip2 sole, just 3.5 mm thick, fuses with a highly asymmetric, downturned last to offer maximum sensitivity and power transfer for the most demanding bouldering and sport climbing routes.

Overview

The Theory is La Sportiva’s dedicated tool for modern indoor and outdoor performance climbing. Its unlined microfiber and suede upper molds to the foot, while the single hook-and-loop strap ensures a secure, rapid fit.
