Caterpillar Footwear Worksport Oxford Steel Toe Work Shoes 89660. Strengthen your valuable skills with the Mens Worksport Ox work shoe from Caterpillar. Polyurethane/Nubuck/mesh uppers deliver a perfect, breathable fit in these tough work shoes. The nylon mesh liner wicks away moisture and perspiration from your feet for drier, cooler all-day wear. The EVA midsoles cushion your step, delivering comfort that lasts. ASTM-approved steel toes offer protection from impacts, falling objects and other worksite hazards. Rated electrical hazard-resistant, these guard against shock in charged environments. The non marking, slip resistant outsoles, command superior traction on a variety of surfaces, and are oil resistant, preventing corrosion and breakdown for longer wear.
