This is not my first pair of climbing shoes from five ten. I have a different pair from 2014 that are 12s and these are at least an inch smaller than this, while being a half size BIGGER. I understand that climbing shoes have to be 'broken in' but the pain these shoes cause my feet make that impossible.. other than the sizing the shoes look great and I'm sure would perform well on the wall if I could get my feet in them. Order several sizes up, or buy somewhere you can try them on..
