Have had foot and ankle pain for years. Tried everything... over the counter pain meds, various style and brand shoes, foot stretches and exercises, physical therapy, etc. Then I tried a pair of these in a department store. Immediately noticed a small difference in my heel pain so I purchased.  Within a few days I had no pain whenever I wore these shoes. After wearing daily for awhile I have no pain at all and am able to wear other shoes with comfort.  But I always go back to Fit Flop as my 'go to' pair for hanging around the house or out on errands and shopping.  I have since bought their shearling slippers and other sandal styles. This particular pair was a gift for my mother-in-law. I have 'converted' several other people into Fit Flop fans!
