The only thing that worked for me was a full wardrobe of vionic footwear. I kick the flip flops off when I'm on the couch or in bed, but my feet touch the floor straight into them. Rolling on a frozen water bottle before bed also helped me a lot
Do a Google search for the best shoes for PF. Unfortunately they can be pricey. Well, pricey to somebody who buys shoes at Wal-Mart and Meijer (me). I threw out a lot of cheap, no-support shoes. We drove to Niagara Falls this summer and stayed on the Canadian side; I did a lot of pre-trip recon online and went sandal shopping at the outlet mall and a few other stores because the exchange rate was pretty favorable. Now I need to do some shopping for cold weather shoes. If I buy shoes online I make sure they have free return shipping or free returns at the local brick-and-mortar store.
