Built to provide workers in the oil and gas industries with exceptional slip resistance and electrical hazard protection, our rugged Timberland PRO® Rigmaster steel-toe work boots feature steel shanks for structural support and Anti-Fatigue Technology footbeds for added shock absorption and energy return. We used full-grain and abrasion-resistant Ever-Guard™ waterproof leather uppers and internal waterproof membranes to ensure maximum waterproof protection as well as blood-borne pathogen resistance. Our breathable, moisture-wicking linings with odor control treatment are made of ReBOTL™ material containing at least 50% recycled plastic. Plus, our heat-, oil-, slip-, and abrasion-resistant, non-marking polyurethane outsoles are designed for industrial traction and feature Ladder Lock™ heels that help grip ladder rungs. Metallic, asymmetrical-shaped toe cap. Meets ASTM F2413 impact (I) and compression (C) requirements when tested to ASTM F2412. Delivers waterproof protection, and also provides blood-borne pathogen resistance as defined by ASTM F1671. Breathable membrane helps protect from diseases caused by blood-borne pathogens, as defined by ASTM F1671. Provides secondary underfoot protection against live electrical circuits, electrically energized conductors, parts or apparatus. Meets the ASTM standards F2413 and F2892 requirements when tested to F2412. A comfort system designed with shock absorbing, geometrical technology that returns energy back to the foot to deliver all day support and comfort. OrthoLite® comfort foam insoles are lightweight, provide moisture transport, antimicrobial function, and long-term cushioning. The ultra-breathable material won't break down or lose cushioning over time, keeping your footwear comfortable and supportive. Highly abrasion-resistant leather that enhances durability in rugged jobsite conditions. Lightweight and rugged, providing cushioning plus slip, oil, and abrasion resistance. Meets the SR requirements of ASTM F2413, F2892, or F3445, when tested to F2913. Microban technology provides an extra layer of protection on footwear fabrics against unpleasant odors, stains, and deterioration caused by bacteria and fungus. Our waterproof footwear incorporates a variety of advanced waterproofing materials, treatments and processes. We start with waterproof leathers that are sealed as part of the tanning process; we then either seam-seal the footwear or use an internal waterproof breathable membrane to help feet stay dry. Tongues and zippers treated with durable water resistant coatings utilize integrated gussets, to further deter water entry.
