The Gridworks safety-toe men's work boots take on freezing, oily, slippery or rough terrain, with cold-formula outsoles built for traction. Waterproof performance and a taller eight-inch height infuse these boots with the protection you need. They have an Anti-Fatigue Technology polyurethane footbed for shock absorption and energy return. They are also breathable and feature moisture-wicking lining with anti-microbial treatment for odor control.
