This steel toe boot is designed to provide all-over support on the jobsite. Nubuck leather upper is fully waterproof and a KEEN.DRY waterproof breathable membrane lets sweat escape as vapor, while keeping water droplets out. In addition, the Dri-Lex footwear lining features highly absorbent and quick-wicking Hydrophobic/Hydrophilic 2-Zone Comfort Technology. Cushioning, metatomical, compression-molded, dual-density EVA/polyurethane footbed offers superior support and is removable for easy care. Asymmetrical left and right-specific steel toes are uniquely anatomically correct for a roomier and more comfortable fit. Patented KEEN.PROTECT shields your foot from rocks and debris with a rubber outsole that wraps up and over your toes. Non-marking rubber outsole is oil and slip-resistant. Contoured heel for secure fit. Reflective webbing for safety. ESS shank for torsional stability.
