Carhartt developed Ground Force work boots to redefine comfort for hard working people on and off the job through advanced engineering, technology and componentry. Every style in the collection incorporates the Carhartt Insite Technology Footbed that is engineered to create maximum arch support to reduce foot fatigue during long days on the job. Storm Defender? Waterproof Breathable Protection is designed to be completely waterproof and to keep your feet dry in most types of wet conditions with a waterproof and breathable membrane. FastDry Technology linings wick away sweat and the lightweight proprietary EVA midsole provides energy recovery and absorbs foot strike impact. The Carhartt Ground Force rubber outsole is cement constructed to be flexible and light weight. When you want your job to be the focus, NOT YOUR FEET.
