Engineered specifically for those who spend long hours on their feet, the Timberland PRO Endurance collection redefines comfort by featuring our exclusive anti-fatigue technology, which absorbs shock and returns energy at key zones of the foot to deliver long-lasting, all-day comfort where you need it most. They constructed the Timberland PRO Endurance 6-Inch Steel Toe from premium, rugged leather and added a slip-, oil- and abrasion-resistant rubber outsole to infuse confidence into every step, regardless of what surface you're on.
