The salt resistant leather upper on this durable work boot is equipped with a waterproof membrane and lined in a breathable moisture-wicking material. It has an Ergo-Fit composite toe cap, designed to match the shape of your foot so your toes have more room to move while still meeting ASTM F2413 impact and compression standards. Inside is our Comfort Core Next Gen footbed, a removable memory foam insole with individual shock absorbing comfort core pillars and cooling air flow channels. The base of this nonmetallic work boot consists of a fiberglass shank for arch support, a PU midsole, a 3-pronged TPU shank for extended mti-directional stability and a TPU defined heel outsole. It meets ASTM F2413 electrical hazard standards for safety boots. If you need a waterproof composite toe boot with flexibility and comfort, try the Georgia Boot FLXPoint ULTRA.
