Just a quick note for the above; if you're looking for a pair of shoes but you're on tight budget you might want to check out Shoe Rack (Exchequer Str, not sure about the other ones) which is having a late summer sale. A lot of really really cheap heels, sandals and flats.
I picked these (not that I need them or anything) but c'mon... at 10 a pair, how can you not? :)
Not too bad for the price huh?
