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 GORE-TEX^® membrane provides protection unmatched by any other waterproof, breathable barrier.

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 transmit heat or cold. Exceeds sole plate puncture resistance standard ASTM F2413-05.

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. The Fire and Ice compound provides superior flame, abrasion, oil, acid, and slip resistance for high traction and durability. 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.

Contoured outsoles are 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.

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.

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.

VIBRAM^® toe bumper provides exceptional abrasion resistance when crawling.

Lighter than steel, doesn't transmit heat or cold. Exceeds toe impact/compression standard ASTM F2413-05.

New advanced impact protection for the metatarsus (the bones extending back from your toes over the instep) is provided by an innovative technology that is soft and flexible for optimum mobility and comfort but hardens upon sudden impact for ultimate protection. Exceeds ASTM F2413-05 for metatarsal impact.
