Timberland has designed heavy-duty Boondock boots to provide industrial-grade protection from every angle. Starting with their 8" tall premium Timberland® leather uppers, they added their molded Timberland PRO® rubber toe protectors that are as thick as standard boot outsoles and backed them with composite safety toes, rigid external heel cups to support lateral movement, puncture resistance, electrical shock protection, and Anti-Fatigue Technology footbeds for all-day shock absorption and energy return. 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 find protection from below with lightweight, All-Weather TPU outsoles featuring heat-, slip-, oil-, and abrasion-resistant, non-marking, enhanced traction for extreme environments.
