The Powertrain EV offers lightweight performance with composite safety toe protection. Not only are they tough enough to handle working on your feet all day with their durable, metal- and mutilation-free uppers of ripstop nylon with premium Raptek microfiber, they feature composite safety toes and electrical hazard protection for an extra margin of safety. Their breathable, moisture-wicking linings are made of ReBOTL™ fabric containing at least 50% recycled plastic with an antimicrobial treatment for odor control. You'll also appreciate their aggressively styled, but lightweight, Anti-Fatigue Technology EVA midsoles and breathable polyurethane footbeds for extra shock absorption and energy return. Plus, our heat-, oil-, slip-, and abrasion-resistant, non-marking Timberland PRO® rubber outsoles offer superior traction.
