We didn't just choose the name Endurance for this Timberland PRO® work boot. It was earned. We built it to help provide performance and protection to help get you through challenging days on the job. Designed with a premium, full-grain waterproof leather upper with an internal waterproof membrane that helps deliver waterproof protection and bloodborne pathogen resistance, and a flexible metatarsal guard with Skydex® technology designed for impact protection. This boot also has a composite safety toe, an Anti-Fatigue Technology footbed, and midsole that helps with shock absorption and energy return, and a breathable, moisture-wicking lining made of ReBOTL™ material containing at least 50% recycled plastic with Microban antimicrobial treatment for odor control. Plus, underneath you'll find our heat-, oil-, slip-, and abrasion-resistant, non-marking rubber outsole designed for traction on and off the job site.
