A long day of logging or utility work calls for nothing short of Carhartts 8-inch logger boot (black)/non-safety. Built Carhartt strong, it's made of oil-tanned leather with a waterproof membrane. For performance, it features Goodyear welt construction with a Vibram rubber outsole that's oil, chemical and slip resistant. A full day of comfort is assured with an OrthoLite insole, padded collar and OrthoLite comfort tongue. There's also a molded TPU (thermoplastic polyurethane) heel counter for stability, and an achilles flex joint for ease of movement.
