Anti-Fatigue Rebound: Energy Max layer compresses under each step and springs back, feeding energy into your stride and easing the drain of long shifts on hard floors Anatomical Cushioning: Engineered to the foot's natural contours so weight spreads evenly and support holds up across the workday, not just out of the box Round-Toe Fit: Pre-shaped to a round-toe last for ARIAT work boots; order your usual US men's shoe size in D (medium), whole sizes 7 to 15 and half sizes 7.5 to 11.10 Moisture-Wicking Liner: Durable top layer pulls sweat away from the sock to help feet stay dry from clock-in to clock-out Cool Open-Cell Core: Temperature-regulating foam vents heat inside the boot so the footbed stays comfortable through warm floors and long hours Ten hours on concrete flattens a stock insole long before it flattens your resolve — and every shift after that lands harder. ARIAT's Energy Max work insole answers with a rebound foam layer that cradles the foot, dissipates pressure, and feeds a measure of every step back into your stride, so legs finish the day with more left in them. Anatomically engineered cushioning supports the foot's natural shape for comfort that holds up across the workday, not just out of the box. A moisture-wicking liner pulls sweat off the sock while the open-cell foam core vents heat, keeping feet cooler and drier inside a work boot. Pre-shaped to a round-toe last, it drops into round-toe ARIAT boots at your usual US men's shoe size — D (medium) width, whole sizes 7 to 15 and half sizes 7.5 to 11.5. Built from 83% polyurethane rebound foam with a 17% polyester liner.
