The Bates Men's Delta-8 Side Zip Boots feature leather and 1680-denier nylon uppers with a breathable mesh lining. Combined midsoles and insoles with iCS technology offer the freedom to choose a comfort setting that works for you thanks to removable disks that can be rotated among 4 zones to control firmness, cushioning, inward stability and outward stability. Slip-resistant rubber outsoles offer traction, and cement construction gives these boots a lightweight, flexible feel.
