We've constructed our Timberland PRO® Endurance 6-Inch Waterproof Steel Toe for the ultimate in safety and jobsite performance. You know the confidence that a steel-toed workboot brings, and we've brought this boot further with safety features such as our Timberland PRO® Rubber outsole, which is oil-, slip- and abrasion-resistant and features a low profile for high surface contact; our anti-fatigue technology to absorb shock and return energy to the foot; and a Steel-Flex® puncture-resistant plate for flexible underfoot protection.
