I have a new pair of heels that aren't appreciably higher than other shoes I own, yet they really hurt my feet. They are the proper size and they do not rub or pinch anywhere, but they really strain the ball of my foot/arch. I am not sure how to define it, as I commonly don't have this problem with shoes. Is there anything I can do to make them wearable? While they are not designer shoes, they are quite cute and I bought them at a great price and I'd like to be able to wear them. Thanks!
