These Goodyear welt constructed 6 in. AMP LT Moc Toe Wedge Work Boots are an extremely comfortable pair of work boots designed for high performance. Their upper is made from premium barnyard proof SPR leather that makes the toe wedge work boots resistant to many caustic alkali and potash, as well as other barnyard acids. Its special tanning process makes it far more abrasion resistant and stronger than conventional leathers. The boots' heel-stabilizing Counter Lock prevents heel slippage and acts as a protectant against tears when kicking off your boots. The interior of this 6 in. 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. The removable AMP LT memory foam insole is a layer of cushioning polyurethane topped with a layer of memory foam for all day extreme comfort. The foundation of the boot includes a fiberglass shank for added stability, a shock absorbing EVA midsole, and a Carbo-Tec Rubber wedge outsole. Our proprietary blend of rubber gives this wedge work boot great heat, chemical, abrasion, slip and oil-resisting properties.
