The P10021486 has a durable all leather waterproof upper and Ariat’s waterproof Pro construction, a mesh lining for breathability, a cushion EVA midsole, Ariat’s patented 4LR (four layer rebound) removable footbed for comfort and energy return, and an oil and slip resistant Duratread outsole with debris release that extends in the front and back of the boot for added boot protection.
