Evolv Yosemite Bum Climbing Shoe - Climb。These brand new unused Yosemite Bum X Evolv climbing shoes are size 11 in US Mens still with tags, no box. I was really excited to finally have a nice pair of crack climbing shoes for Joshua Tree, but unfortunately, these were too tight for me! I normally wear 10.5 Mens for running and walking shoes, and 11M for Evolv climbing shoes but I think I would have needed about 0.5-1 sizes bigger. It has not been worn for climbing. And I confirmed with Yosemite Bum - they will still honor the 1 free resole. These are must have crack/trad climbing shoes!
