BANANA REPUBLIC Gabie Ballet Flats

I bought these shoes on eBay - Retail: US$108. I paid US$26!

I'm a US5 or 5.5, and these are tagged 5.5, but they're too big :( My feet slip out when I walk. I'm going to try and buy one of those heel-huggers and see if it'll fit me then. Otherwise, back onto eBay it'll go :( They're so lovely too! 100% leather with a leather sole to boot, and they look absolutely *adorable* on :P
