Using insoles for 1/2 size too big is one thing, but a whole size too big is another. I don't think insoles will be enough to fill them out...I've tried with no success. They'll likely still be too big (especially after they stretch out a bit too), and will be impossible to walk in. Good luck!
i used insoles but they didnt work for me either.. esp after they stretch so i just started to buy my pumps a 1/2 size smaller
I hate to be an old crank, but wearing shoes that fit is essential to keeping your feet healthy so you can continue to wear heels and pumps. If they don't fit, return them!
