Hi Guys and Guyettes: I have a question about buying shoes. I am in the process of trying to buy new shoes and am having no end of trouble. Every pair I try on rides up in the back whenever I walk in them. Two years ago, I spent two months looking for tennis shoes that didn't rub the back of foot. When I was younger, I never seemed to have this problem. Could it be that I walk differently now because of the PD (dx'ed about 2 yrs ago) and that is what is causing my problem? Does anyone else have problems trying to find shoes that are comfortable for walking? Ron Reiner (49/2)
