For climbing shoes, these are super comfortable!(Keep in mind, climbing shoes are supposed to feel like they can only be worn for about 10 minutes at a time, because they're supposed to fit so tight)...and having said that, these are very comfortable for climbing shoes. These ones also fit very true to size. I love the sole on these, they give fantastic grip and the perfect amount of support. I also like the heel support on these, they cup my heel great! A fantastic climbing shoe...the one down side would be lack of tackiness, the sole of the shoe isn't very sticky after a while...other than that, love the shoe!!!
