Built with American ingenuity, the KEEN Utility Men's Portland 6” Composite Toe Work Boot offers revolutionary KEEN.BELLOWS FLEX technology to flex, and bend with up to 3x less torque than other work boots making work below the knees that much easier. Weighing 27.55 oz / 781 g (per boot), made with durable, waterproof leather and featuring a moisture-wicking lining the Portland 6” KBF Composite Toe Waterproof work boots for men are built off KEEN's traditional wider footwear form. KEEN Utility products offer removable insoles. These dependable work boots are great for heavy-duty work in construction, manufacturing, utilities, and transportation. All KEEN Utility products use a natural, probiotic-based technology called CleansportNXT for breaking down odor in sweat; while also sourcing leather from tanneries certified by the Leather Working Group (LWG) which is the gold-standard for responsibly sourced leather. KEEN Utility believes in creating work boots that make work and life better. To further support that mission, KEEN Utility has been “Putting Good to Work” through its non-profit partnerships within the Project Build program. From helping put veterans back on their feet to supporting conservation corps work across the country, KEEN Utility puts good to work, first.
