I wondered if anyone has shoes a bit too big for them - is there anything you can get to make them a bit smaller? I remember years ago I tried these sticky plaster type things you put in the heal but it didn't make any difference. I'm asking as i have seen some shoes I love but the 7's are too tight and the 8's too big - i love them though and was hoping there was some way I could get the 8's and make them fit! Thanks for any tips.
