So I got these in 12.5 after trying 11.5 and 12. My street shoe is usually 11.5. Really a 12 on the left foot and a 12.5 on the right would be perfect, but hey they were clearance. They are climbing well so far, though I can't help feeling I should have stuck it out with the 12s. That said, they're the comfiest down turned shoe I've ever tried.
