The Portland from Keen Utility 

The Keen Utility Portland work boots are built USA tough and strong and ready to get to work. These work boots have state-of-the-art Carbon-Fiber Composite Safety Toes that are much lighter than steel toe boots, while offering the same ASTM protections on the job. Keen makes their work boots with a 30-day comfort guarantee because they are built to feel great while on your feet all day. Made with their KEEN. BELLOWS FLEX technology, walking, bending, and flexing in these work boots is 3x easier than other work boots on the market and that makes them a great choice for roofers, construction workers, and plumbers.
Keen Utility Work Boots use Keen's patented Hybrid Technology to produce work boots that will be tough but also extremely comfortable. The Keen Utility line of boots provides all-day comfort because they have been engineered with enhanced cushioning and just the right amount of Arch Support to stave off foot fatigue. This is why Keen's Utility Boots have become an in-store customer favorite in all of our five store locations, especially with local factory workers who must stand on concrete floors all day. All of Keen's Work Boots in their Utility Series are built solid and made to last.
