I bought these shoes back in March--my first pair of climbing shoes, after climbing in gym shoes for 3 months. I can't say enough good things about them. I bought them 1.5 sizes down from my street shoe size, so the initial break in period was a bit rough (read taped up toes for a while...) but once I got them broken in, they were amazing. They did stretch a little--I bought them to fit my smaller foot, and now, they are perfect (although I still recommend bringing a pair of other shoes for the belay/approach to keep your feet happy if you buy them small.) The construction allows them to mold to your feet, making for a shoe that I don't usually tie, unless I know I'm going to be using a heel hook. In the gym or outside, I can stand on stuff that my friends with their trad/not so aggressive shoes can't touch, and be comfortable there.
I can't recommend these enough. They're absolutely worth the money.
