We designed extra large composite safety toes for our Ballast work boots to help maximize your all-day comfort on the job site with their generous internal volume. Starting with premium Timberland full-grain leather uppers, we utilized Goodyear welt Cast-Bond construction for durability and added flexible, non-metallic plates for puncture resistance, fiberglass shanks for structural support, essential electrical shock resistance, Anti-Fatigue Technology footbeds that absorb shock and return energy with every step, and breathable, moisture-wicking linings made of ReBOTL fabric containing at least 50% recycled plastic with an antimicrobial treatment for odor control. Plus, to help ensure your traction in all weather conditions, these boots feature heat-, oil-, slip-, and abrasion-resistant, non-marking, lightweight All-Weather TPU outsoles.
