The Challenger line from Hoka used to have the full name 'Challenger ATR' to indicate that this was an “all-terrain” – i.e. both road and trail – shoe. Size 6 M good condition/ orange in color. I have many running shoes and alternate between shoes. My shoes I put up are gently worn and super good condition because of alternating between. Thinning out my collection. Smoke free environment. Fast ship time.
