Odd toe box
I bought these shoes wanting a mildly aggressive comfortable edging shoe for the granite I typically climb on. I sized in line with my regular shoe size of 10.5 and the fit was snug. The shoe performed beyond its non aggressive look and stuck amazingly on small edges on granite and plastic. After about 3 months of heavy use the toe box had not budged in the least and the exceptional pressure on the joint of my big toe became too much to bear (that and the odor).
Bottom line, if these fit your feet the rubber is amazing and the shoe performs well but if you have a slightly longer big toe you are probably in for a world of pain.
