The Blundstone Classic Chelsea Boots are ankle-high leather boots, with a shaft height of approximately 5 inches (12.7 cm) and a heel height of about 1.5 inches (3.8 cm). The boots feature a polyurethane midsole for comfort and a durable, slip-resistant thermo-polyurethane outsole. They incorporate XRD® Technology in the heel strike zone to provide excellent shock absorption and reduce wearer fatigue. The interior includes a leather lining for comfort, a removable EVA comfort footbed, and an extra set of footbeds is provided to allow for slight size adjustment. These unisex boots are considered true to size, but ordering a half size larger only increases the width, not the length, to accommodate wider feet.
