My shoes get well worn. Red chillis I bought off here two months ago are completely blown now, toe almost through the end. Felt fine indoor bouldering in them today upto v5 level. Done lots of limestone climbing on them the last two weeks with no edge and even pushed my grade!
If you are using your toes effectively then I find shoes don't hinder you much. I find I can really smear the toe in on holds when shoes are worn.
