Sizes:
Men's: 5-12.5 (full and half sizes), 13-17 (full sizes only) in Medium, Wide, and X-Wide widths. Heavyweight, flame-resistant and waterproof leather for durable performance. Leather has added reflective material at the heel for added nighttime visibility. Specially softened tumbled leather in high flex areas to move with you. A full-height bootie liner made from a package of Cambrelle®, 300g insulation, and CROSSTECH® moisture barrier provides protection unmatched by an other waterproof, breathable barrier. Contoured outsoles are cement bonded to the bottom and sides of the upper using a 2-part cross-linking adhesive that forms a bond stronger than the materials it attaches. Without stiff welts and ribbed mid-soles, this attachment process is far more flexible. Molded outsole wraps onto the leather upper for athletic shoe performance. Flame, abrasion, oil, acid, and slip resistant compound engineered for high-traction and durability even during prolonged exposure to extremes of heat and cold. Siping lines cut into flat areas open up when flexed to provide additional traction on water and ice. Self-cleaning lugs and omni-direction tread pattern designed for superior performance in all terrains and when working on ladders. High-performance composite penetration-resistant insole is made from multiple layers of HT ceramic material - like ballistic armor for your feet. Far more flexible than a steel plate and doesn't transmit heat or cold. Exceeds NFPA standards for safety. Boot uppers are lasted to a molded and contoured lasting board with a built-in flex zone in the forefoot and a torsionally stable heel. Works together with the 3D molded footbed to conform to the shape of your foot. Lighter than steel, doesn't transmit heat or cold, and springs back to shape better. Lighter than steel, doesn't transmit heat or cold, and exceeds NFPA standards for safety. Impact resistant molded foam metatarsal guard provides lightweight and flexible impact protection.
A rugged heel counter is individually molded to fit each size perfectly. Made from the same rugged compound as the outsole for abrasion resistance when crawling. Cemented and 2-needle stitched to the vamp. Removable footbed is contoured to cradle and cushion the bottom of your foot and to provide arch support. Moisture wicking and anti-microbial fabric top layer. A second removable footbed is provided with every pair for a custom fit. Use this thicker footbed for a snugger fit or when wearing with lighter socks. Boots combine the advantages of a lace-up for custom fit and the convenience and speed of a zipper closure with the lace-in, flame-resistant front zipper closure.
