Heavyweight, flame resistant and waterproof leather for durable performance.  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 any other waterproof, breathable barrier. Flame-resistant fluorescent and reflective material for added visibility. Anatomical HEELPORT^TM foam insert holds your heel securely so it won't slip while cushioning your ankle. A rugged heel counter is individually molded to fit each size perfectly. 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 trasmit heat or cold.  Exceeds NFPA standards for safety. Lighter than steel, doesn't transmit heat or cold and springs back to shape better. 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 the 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. Pull-straps are internally reinforced for added strength and to keep them upright.  Straps are securely box and cross stitched to keep them on for good. A protective shield of KEVLAR® and NOMEX® fiber batting protects the CROSSTECH® moisture barrier, provides cut resistance, and adds thermal protection. Molded and padded shin guard provides extra protection when you are working on a ladder. Lighter than steel, doesn't transmit heat or cold and exceeds NFPA standards for safety. 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 the thicker footbed for a snugger fit or when wearing with lighter socks. Boot uppers are lasted to a molded and countoured 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. Contoured outsoles are cement bonded to the bottom and sides of the upper using a 2-part 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. Available in men's, women's, and wide calf in medium, wide, and x-wide widths.
