Our Timberland PRO® Powertrain Sport athletic work boots offer lightweight performance, but they're all business when it comes to protection. Beginning with mutilation-free, premium ripstop nylon uppers, we added abrasion-resistant screen-prints and TPU toe overlays for extra durability. Not only are they tough enough to handle working on your feet all day, they also feature alloy safety toes, electrical hazard protection, and Anti-Fatigue Technology for all-day shock absorption and energy return. Their breathable, moisture-wicking mesh linings are made of ReBOTL™ fabric containing at least 50% recycled plastic with an antimicrobial treatment for odor control. Plus, their outsoles are made of heat-, oil-, slip-, and abrasion-resistant, non-marking polyurethane for enhanced traction and comfort.
