In reply to GlasgowMatt:
Here's the thing. When you start out you tend to have very poor footwork compared to what you may achieve in 5-10 years. Don't take offence, pretty much anyone whoever climbed experiences this. As you progress your footwork improves and your shoes take less of a battering, i.e. you buy less often.
I remember getting through 5-6 pairs in the first couple of years but having climbed for 8 years, I bought my last pair 15 months after the previous. That assumes at least six solid months on rock and 3 x p/w indoors if not during that time. It'll get better and cheaper, unless you fancy better shoes!
On the flip side, maybe it is a design fault. Perhaps speak to staff or more experienced climbers who you can show the problem to.
