Hi:
I have had PF for years. I even had shock treatments on my foot. I find that the Easy Spirit Travel Time tennis shoes work for me (open back). Also the Yellow Box flip flops at Belk are awesome. I also find that once the shoes start to get older the arch breaks down and it's time to replace them because the pain comes back. For dress shoes I wear Easy Spirit. You can find them at
www.easyspirit.com for a wider selection. I don't have the pain anymore unless I stand in one spot for too long.
