I've owned been climbing for a 4 years now and I've tried out 8 or 9 different shoes, but I've never worn any that helped so much on overhangs and crazy boulder problems. They heel hook like a charm, edge like champs and stay on when you need them to. Obviously they're not gonna be the comfiest shoes because of their aggressive nature. But as a climber you should accept that climbing hard usually hurts. The only problem I've heard about anyone having with these shoes is that the straps are really weak. I know 2 guys who have broken the straps on these bad boys. I've been wearing mine for a little over a year and as long as you tighten them gently the straps won't break.
