Engineered for competitive trail and adventure runners La Sportiva's Exum Ridge represents the pinnacle of durable performance for discriminating racers. All facets of this lightweight and highly durable off-road shoe are specialized for moving ahead at the fastest speeds possible. The lightweight synthetic leather and mesh upper repels light water and precipitation but large flex windows give the upper astounding flex and allow for fast draining when immersed in water. A sophisticated multi-component suspension balances RockShock cushioning to decrease pronation with firm Memlex medial support. At the bottom is La Sportiva's proven FriXion® Black Dot Rubber sole with trail tread for optimal grip on a range of steep surfaces.
