The new Caldera 5 is the redesigned version of a breathable mesh upper with a midsole and outsole that helps it conform to the ground. The TPU toe cap and mudguard provide added protection on your mountain runs. The design features a lightweight, durable mesh upper, a lace protector to prevent snagging, integrated heel gaiter tab and a grippy traction system that provides perfect grip on descents and ascents. The novelty in this model is the incorporation of new Ghillies in the midfoot that allow for more flexibility and support. It is a shoe that offers cushioning and great traction.
