Returning for its sixth iteration, the Challenger ATR 6 furthers its reputation for versatility. As its name suggests, this adaptable, all-terrain shoe defies convention performing light on the trail and smooth on the street, thanks to its midsole geometry and outsole construction. Dynamically designed for versatile traction, its distinctive outsole has zonal construction to optimize grip and weight. One of the best walking shoes for bunions developed with broad, closely spaced zonal lugs, the Challenger ATR 6s outsole delivers smooth transitions from one surface to another. This seasons iteration utilizes recycled Unifi REPREVE yarn derived from post-consumer waste plastic. Podiatrist shoes recommended.
