Evolv Yosemite Bum (Medium Volume) is a big-wall focused lace-up climbing shoes built for confident crack and edge climbing with quick entry and on-the-fly fit tuning. The split tongue opens wide to make transitions at belays faster, while the adjustable lacing helps keep the feel consistent as feet change through long days. With a medium-volume shape and neutral camber, it aims for a more natural stance than very narrow, aggressively shaped alternatives. Each pair includes one free resole to help keep the shoes in use longer.
