High wear rubber grip pad for control, with replaceable nylon wear pad on the medial side. Flexibly and movement from two pivot points on the lateral and medial side work together. Hyperextension and hyperflexion protection built in. Replaceable "Easy Action" cam lock buckles with adjustable locking straps. Air Teflon Cambrelle® mesh lining protects the feet while also protecting the integrity of the boot.
