In reply to siouxchief:
Most of the advice from previous posters' is good. Not so sure about skin tight though.
Climbing shoes should fit firmly without being 'floppy' so you can get a more positive toe/foot placement on holds.
Remember, on hot days your feet will expand making them feel much tighter. Check out different linings
on the inside of shoes too. With or without socks is just a personal comfort thing, so don't follow the herd.
As a beginner you don't really need a top end technical shoe. In time you will naturally go that way with experience.
Final comment. After 40 years of cramming my feet into too tight shoes I have a lovely painful bunion!
