The KEEN Utility Men's Portland 6" Composite Toe Work Boot features advanced KEEN.BELLOWS FLEX technology that flexes and bends with up to 3x less torque than other boots, making below-knee work easier. At 27.55 oz / 781 g (per boot), these waterproof leather boots are made with a wider form and have a moisture-wicking lining. Removable insoles and CleansportNXT probiotic-based odor control technology make these sturdy work boots ideal for heavy-duty occupations in construction, manufacturing, utilities and transport. Moreover, KEEN Utility uses leather from LWG-certified tanneries, and supports non-profit partnerships through their Project Build program.
