I have extremely small feet. Some brands' size 5 is still slightly too big. When that happens, I go look in the kids section to see if there is ANYTHING that will fit my foot. I'm going to begin teaching in the fall, so my cheap dress shoes that I've had for years won't work because they give me blisters if I wear them for more than a few hours. Is there a good place with like a HUGE selection of shoes, maybe even specializing in smaller feet? Thanks.
