A sporty style that is always ready for action the Impulse M keeps mens feet feeling fit on everything from high energy walks to all out jogs. The sleek design features highly breathable polyester mesh with reinforcements for extra foot support. A 100 percent waterproof and breathable GORE-TEX membrane gives complete wet weather protection. For all day comfort, a molded EVA midsole absorbs shocks and a comfy insole conforms to your foot. The slightly wider Nordic last locks the heel to prevent blisters, but leaves plenty of room for the toes. Underneath, a soft UGC rubber sole grips on all types of surfaces, so you can hit the trail or pavement, whatever the weather. "
