Designed for a generous fit, our Timberland PRO Hyperion work hiker is built to take on formidable conditions on the job with the comfort and performance of your favorite hiking boot. This alloy safety-toe work boot offers electrical hazard protection and its rugged, Premium Timberland waterproof leather upper features an internal waterproof membrane for maximum protection from water intrusion. We've also added an abrasion-resistant Ever-Guard leather heel and backstay with rubber toe for extra durability in these high-wear areas. The breathable, moisture-wicking lining is made of ReBOTL fabric containing at least 50% recycled plastic. Underneath, the outsole is made of heat-, oil-, slip-, and abrasion-resistant, non-marking Vibram rubber with a Ladder Lock heel that helps grip ladder rungs.
