Hello! I have been living with PF for years. Everytime we go to Disney my feet are ruined by the end of the trip. I have tried many things on previous trips and have found some things that help but still end up with sore feet and swollen ankles. We are starting to plan a summer vacation to WDW. I just found out about a certain product and was wondering if anyone has tried this in the parks: Koprez foot sleeves. Anyone use this product at all before- especially in the parks? If so, was it comfortable to wear/did it make you too hot? Thanks!
