Incidentally, I'm selling a pair of boots on ebay (click for link) that have been sitting in my cupboard for a while- I bought 2 pairs of them online to make sure I got the right size and forgot to return this pair.
These are a true size 5 (i.e. too big for my size 4-4.5 feet). My size 4's have been majorly comfy for clubbing and stand up great to having beer spilled all over them. Just saying. xoxo
