You'll get a lot of performance out of Carhartts 8-Inch bison work boot/non-safety-toe because they put so much into them. Crafted from oil-tanned leather, it features direct-attached welt construction with a dual-density PU (polyurethane) outsole that's oil, chemical and slip resistant. Built with a waterproof membrane, it includes an OrthoLite insole, padded collar and OrthoLite comfort tongue. For stability, the boot is constructed with a molded TPU (thermoplastic polyurethane) heel counter and achilles flex joint.
