Okay, so here's the deal! I wear a size 9 street shoe and originally bought these shoes in an 8.5 and they hurt bad when I got them. However, only after a week or so of climbing (I climb a lot) they were too big and sloppy on my feet. They will stretch!!! I sent them back and after the advise of a friend went with a 7.5. They still hurt the first little bit, but now they totally rock!!!! These shoes are so precise!! I love the Faceted edge technology, they are a great design. I feel that I'm climbing a lot better. I totally recommend these shoes!! You just might want to size down a little more than you thought!!
