These shoes are awesome. I have really wide feet, and until now I've always had to go with lace-up shoes in order to be able to fit into shoes that are the right length for my foot. I went out on a limb with these shoes and I was pleasantly surprised that while the break-in period was very painful (I had to pop my heels out 3/4 of the way up a climb), they're mostly leather and stretched out really nicely (they remind me of the Testarossas in that way) and now they fit great. I sized these shoes the same as my testarossas (38).
As for the no-edge concept, I didn't really have any major issues getting used to it. They're definitely more sensitive which is what I was looking for so I'm very happy. Heel hooks and toe hooks are great as well. Overall 5 stars.
