With the release of the Pittsburgh Energy, KEEN Utility incorporates the proven work-hiker performance of the original Pittsburgh for a more nimble, easier-wearing work experience. In addition to its lighter weight, this medium-duty boot offers additional cushioning and flexibility with comfort enhancements, including a KEEN.ReGEN midsole that returns 50% more energy than standard EVA foam; a KEEN.DRY waterproof, breathable membrane; and a TPU shank for midfoot support. At the same time, the Pittsburgh energy does not sacrifice when it comes to safety features, including asymmetrical carbon-fiber toes that are 15% lighter than steel, an oil- and slip-resistant outsole, and an EH rating to serve as a secondary source of protection from live circuits. The new Pittsburgh Energy will be available in two colorways for men.
