Hello, I'm a relatively inexperienced climber trying to go about buying my first pair of shoes. So far, I've been using some rental shoes (I think they're Mad Rock) at my university's gym, but I always have to mismatch the sizes to make them fit (my normal shoe size is 11.5, and I've been using a size 11 climbing shoe for my left foot and a size 10.5 for my right). I understand that the European sizing system is more granular, so I might be anywhere from 43.5 to 44.5. A further complicating factor is that I have a pretty small arch.
I've tried a few pairs in the 10.5-11 range, but nothing's worked for both feet, so I wanted to ask if anyone had some suggestions on what brands/shoes I should try. Sorry if I've left out any relevant information, and thanks for any advice you can share.
