Don't buy shoes that hurt. Sorry to break it to you, but you're probably not going to break in those painful shoes. "A shoe should feel comfortable when you try it on in the store," says Summers. "If it feels too tight in the store, it will be too tight at home and may even feel worse after being worn for a little while." That said, shoes can be stretched and modified for certain foot deformities such as bunions and hammertoes, says Brummer. Use good judgment—and walk away if you have any doubts. Your (happy) feet will thank you later.
