Original S.W.A.T. Footwear's collection of waterproof boots now meet the ASTM F1671-07 standards for blood borne pathogen resistance. All of the waterproof models have a waterproof breathable internal membrane that effectively protects the wearer from bloodborne pathogens. The collection consists of 3 models: the affordable WinX2 waterproof boot, the Tactical Waterproof, and the Air M.T. insulated side zip boot. The 8-inch WinX2 model features a slip- and oil-resistant outsole, including a unique arch ladder tread for extra grip on rope rappels. It is uniform-code and built to last. The Original S.W.A.T. 9-inch Tactical Waterproof boot has an outsole that meets the ASTM F 489-96 standards for slip- and oil-resistance, as do all boots in the collection. This boot is completely airport friendly with its composite non-metallic shank. The Air M.T. Side Zip boot is not only waterproof but insulated as well with 200 gram 3M Thinsulate Insulation. It features a gusseted YKK branded side zipper with a Velcro secure-tab. The shock absorbing midsole incorporates air cushion technology with injection molded EVA for added comfort.
