The Georgia Giant Revamp Waterproof Work Boot is not just your basic work boot. These eight inch lace up boots are constructed from full-grain SPR leather that is both stronger and more abrasion resistant that conventional leathers. Dual functioning hardware gives you the option of hooks or eyelets. A removable leather Comfort Cover tongue protector over a synthetic padded tongue allows you to have the protection of leather without the pinch points. The heel features the Counter Lock System designed to prevent heel slippage. The interior is lined in high performance mesh and is equipped with the Georgia Waterproof System. The Georgia waterproofing is designed to allow air in keeping your boots breathable while keeping water and muck from penetrating the boot. Also inside is the removable AMP LT memory foam insole. It's a layer of polyurethane topped with memory foam to give you a super comfortable customizable fit. A double ribbed tempered steel shank, cushioning EVA midsole and oil and slip resistant polyurethane outsole make up the foundation of the boot. It's joined to the upper through an incredibly durable Goodyear® welt. These work boots meet the ASTM F2892 electrical hazard standards for soft toe footwear.
