Our Timberland PRO® Gridworks work boots take on freezing, oily, slippery, and rough terrain, with lightweight, cold-formula outsoles built for traction. Their job site performance features include rugged Premium Timberland® full-grain, waterproof leather uppers with internal waterproof membranes that offer maximum waterproof protection, Anti-Fatigue Technology footbeds that absorb shock and return energy to your feet with every step, and breathable, moisture-wicking linings made of ReBOTL™ fabric containing at least 50% recycled plastic. We reinforced these boots with alloy safety toes, electrical hazard protection, and all-weather outsoles for superior traction in demanding work environments.
