I don't have to wear socks!
This is a fantastic product.  I bought some new flats to wear last summer and was so disappointed to discover they wore terrible raw spots on the back of both ankles.  I tried some cushioned strips for the shoes but they didn't help at all.  Although the Blister Defense was a little expensive, I bought it and carefully kept my receipt and the packaging to take advantage of the money-back-guarantee.  I was happily surprised to find Blister Defense prevented those painful raw spots.  No need to get my money back.  Now I can wear flats without socks!  SO happy I found this product!
