Like a glove
The fit is perfect for anyone with a wide toe box. My favorite pair of climbing shoes I have encountered is the La Sportiva Miura lace up. This shoe fits very similar. Not too aggressive, heel feels solid, and the lining is made of a mesh style material for breathability. I read a lot of reviews saying that the shoe stretched too much, but we will see. I wear a size 11 in a street shoe, I bought an 11 in this shoe, and it fits just the way I like it. The only reason for not rating them 5 stars, is that I haven't gone out sending in them yet!
