Bought a fab pair of silver mules with wedge sole yesterday. I'm not describing them well but they are beautiful! I was between sizes and stupidly went with the smaller size. They are agony. I can't return as I didnt realise till I'd worn them outside! I'm sat here with fluffy socks under them after trying the hairdryer trick as per google but don't feel any different! Any tips? I can't bear not to wear them!
