Our Timberland PRO Powertrain Sport athletic work shoes offer lightweight performance, but they're all business when it comes to protection. Not only are they tough enough to handle working on your feet all day, they feature alloy safety toes, electrical hazard protection, and Anti-Fatigue Technology for all-day shock absorption and energy return. Their breathable linings are made of ReBOTL fabric containing at least 50% recycled plastic. Plus, their outsoles are constructed of heat-, oil-, slip-, and abrasion-resistant, non-marking polyurethane for enhanced traction.
