The Goodyear welt constructed AMP LT waterproof moc-toe wedge work boot is an extremely comfortable soft toe work boot designed for high performance.The 6-inch upper is made from premium barnyard proof SPR leather that resists many caustic alkali and potash, as well as other barnyard acids. A special tanning process makes it far more abrasion resistant and stronger than conventional leathers. A heel-stabilizing Counter Lock prevents heel slippage and acts as a protectant against tears when kicking off your boots. The foundation of the boot includes a fiberglass shank for added stability, a shock absorbing EVA midsole, and a Carbo-Tec Rubber wedge outsole. A proprietary blend of rubber gives this wedge work boot great heat, chemical, abrasion, slip and oil-resisting properties. It meets ASTM F2892 electrical hazard standards for soft toe safety footwear.The interior of this wedge work boot is equipped with a guaranteed waterproofing system and lined with a soft performance mesh. The 3-D molded counter pocket provides additional heel support and comfort. A removable AMP LT memory foam insole is a layer of cushioning polyurethane topped with a layer of memory foam for all day extreme comfort.
