I love these shoes! They are my favorite to climb in for hard bouldering routes and work best for overhanging toughies. I mostly climb in the gym, but have climbed with them outdoors as well. They are equally effective in either arena. They are super sensetive, so I always trust my feet because I can feel holds so well. After a while, they fit like a glove and wrap around your feet. The downturned last also provide lots of power as long as the shoe is sized properly. That being said, there are some specifics that need to be noted. These shoes stretch more than any shoe I've ever used. I wear a 10 in street shoe, 9 in most climbing (anasazi, mocassym) and bought these in an 8. They have stretched one size so far and I think they will stretch a bit more. I could have gone down to a 7.5 with the amount of stretch in these shoes. Keep that in mind when sizing. There will be pain at first, but it's well worth it. The shoes are so soft that it goes away quickly. This also means that relatively strong feet are required. Their softness means less support and more strength required from your feet. All in all, with the proper sizing and use, these shoes are like climbing barefoot if your feet were hands! Highly recommended!
