Step into refreshingly lightweight KEEN San Jose Aluminum-Toe Work Boots for Men for serious durability with serious comfort. Air-injected midsoles and lightweight aluminum safety toes deliver epically light wearing, while an unlined waterproof leather upper means no break-in period. KEEN Luftcell air-infused polyurethane midsoles provide weightless comfort, while siped, oil- and slip-resistant non-marking rubber outsoles disperse liquids quickly for better traction than ordinary lightweight work boots. A TPU shank enhances mid foot support, and acclaimed Cleansport NXT naturally reduces odors. The midsoles meet ASTM D471-06 903# oil and isooctane chemical resistance standards, while the boots meet ASTM F1677-96 MARK II Non-Slip Testing Standards, ASTM F2412-17 and F2413-17 M I/75 C/75 EH Standards, and ASTM F2913-17 SATRA Non-Slip Testing Standards, for versatile work-ready performance. The removable, metatomical polyurethane footbeds complete the comfort-minded design of these high-performance KEEN work boots. Average weight per pair: 1 lb. 10 oz. Imported.
