Repeating what others have said, fit is everything. My most beloved technical climbing shoes are a now-discontinued model that are just the right shape for me. Nobody but me seemed to have anything good to say about them, but I climb much better in them, despite the near-polished rubber and occasional hole, than a brand-spanky new pair that are slightly too wide.
With a good fit, no air space anywhere in the shoe, you can also go a size smaller without creating the points of blistery agony you get from a shoe that's a little wrong in the heel/too narrow/whatever. |
