We designed our heavy-duty Boondock manufacturing boots to provide industrial-grade protection from every angle while tackling slippery and wet job sites. Our 6" tall boots are made of premium Timberland® full-grain, waterproof leather uppers with an internal waterproof membrane that helps make them impervious to the wettest conditions and blood-borne pathogens. We added electrical shock protection, flexible, non-metallic plates for puncture resistance, molded Vibram rubber toe protectors backed with composite safety toes powered by Carbon Shield™ technology for extra strength, and ExoSpine™ technology that provides enhanced heel fit, lasting structure, and an abrasion-resistant "kick-off" backing for easy removal. Plus, Vibram Fire & Ice™ rubber outsoles that maintain their flexibility in freezing temperatures. For all-day comfort, you'll find StepPropel™ footbeds that compress to store your energy and then rebound to release that energy back to your feet with every step, breathable and moisture-wicking linings made of ReBOTL™ fabric containing at least 50% recycled plastic, and an antimicrobial treatment for odor control.
