Take on the toughest jobs in Carhartts 6-inch blucher work boot (brown)/non-safety. Featuring an oil-, chemical- and slip-resistant sole, it's crafted from oil-tanned leather with a waterproof membrane. An OrthoLite insole, padded collar and OrthoLite comfort tongue add comfort, while a molded TPU (thermoplastic polyurethane) heel counter with an achilles flex joint improve performance. The boot also features the durability of an EVA (ethylene vinyl acetate) midsole and Vibram rubber outsole.
