The Marius Boots from CWB are lightweight with a lace-adjustable heel lock strap. The Gen6-Plate with Air Shock Heel is the lightest, strongest, and smallest on the market. Heel Lock Hinge on the boots means zero heel lift and a taller metal lever. Superfeet Premium Insole with patented stabilizer cap and SOS shock absorption heel offer optimal shock absorption.
