The Carhartt 10" CSA Rugged Flex 400G CT WP is a lace-up style of boot built to keep you safe, dry and comfortable while spending hours on your feet. The Storm Defender waterproof breathable membrane keeps your feet dry, working in tandem to withstand harsh and unpredictable weather with the 400g 3M Thinsulate insulation that keeps your feet warm. A wide composite toe protects your toes from drops while allowing your toes to have room to move, and the Rugged Flex outsole is built to be oil, chemical and slip resistant. These shoes can go almost anywhere on any terrain while keeping you going with fatigue fighting cushion insoles. The durable cement construction and rubber toe bumper mean you can count on these boots time and time again.
