i boulder the majority of my climbing and you can feel that these are not that non-bouldering friendly, but for boulder moves these are great. i'm very happy with them and their style, and would definitely suggest them to a boulderer. the one problem i had with them is that i had to size up one from my regular street shoe size. i am all for a tight climbing shoe but my street shoe size was ridiculous, i could just get my foot in and after a minute my feet were too sore. one size up and they are perfect, still very tight, but not stupid tight.
