It is ideal for long days of climbing shoe. You can put those shows and a thousand times and never get tired. It's super comfortable! The sole is excellent, where you put the shoe there is gripped like a cat. The only against that I found is that when you force the heel is much wrinkle. The sole in that area is very fragile.
This is a great shoe. I've only been climbing since January of this year . I don't have a lot of experience with different shoes. These seem to stick nicely on the indoor walls. I haven't used them outside yet. Getting the right size is tricky. After readin many reviews I ordered a full size smaller. Big mistake! I went and exchanged them for my street shoe size. Still tight but much better and I'm sure that they will stretch after a few more climbs in them.
