These shoes smear and edge like nobody's bussiness, yet they are still aggressive and stiff enough to be able to hold a toe on small holds. I have mine sized very aggressively. I wear a size 12 street shoe and i have these in an 11. They hurt the first time i put them on, but after that they have performed very well and I can climb almost anything in them. I do however prefer a more aggressive shoe for anything more than a 60 degree overhang or roof.
