FIRESTORMTM Leather
Heavy-duty, flame-resistant and waterproof full-grain cattle hide leather measuring 2.0-2.2mm of thickness for durable tear and puncture resistance. Tumbled full-grain cattle hide leather in collar and flex areas for mobility.
Aluminized Shield Liner
A full-height shield liner is situated between the leather outer shell and the bootie shield liner layers. The liner is made from Aluminized PBI® fabric consisting of a knit fabric substrate laminated with aluminized reflective silver film component certified to NFPA 1971.
Bootie-Shield Liner
Two full-height layers of a protective bootie-shield are positioned between the aluminized shield and the barrier bootie to provide additional thermal protection.
Enhanced ePTFE Barrier Bootie
A full-height bootie liner made from a package of Cambrelle®, 300g insulation, and enhanced ePTFE barrier provides liquid and chemical protection as defined by the specified NFPA standards.
Cement Construction
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.
VIBRAM® Synthetic Rubber Contoured Cup Outsole
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.
