10/07/2020
Keen footwear from Portland, Oregon, has unveiled a new technology that will be used in hiking shoes set to debut next year.
Called the Keen.Bellows Flex, the technology is a flexible TPU piece that will be inserted into the forefoot of hiking shoes. Described as an accordion-style TPU, the piece is used in the forefoot area to make it easier for a wearer to flex in these high-use areas of the shoe.
