Go into a well stocked shop and try on as many pairs as you can. Anasazi velcro's, sportiva katanas, scarpa vapour's are all good upgrades over your "beginner" shoes ( i use the term beginner very loosely here as i still see beasts crush in vantages). There are also lace up versions of those one's mentioned which you could try too. Ask the guy in the store (assuming he knows what he's talking about) about slim fit versus wide fit shoes; for example the five ten velcro and the moccasym, i've found they tend to fit people with wider feet better than say the white lace-ups which are much lower volume.
At the end of the day you should be favouring fit over aggression. Don't buy shoes so tight that your getting a burning sensation in your toe joints, this is bad. But your toes should feel bunched up in the toe box, snug would be a good term to use.
