Should not be sold on Amazon...
I dont normally post reviews however when you order an item for someone who has a medical issue you need it to work. The manufacturer needs to fix the design flaw for the heel strap! The heel strap does not stay amd it does not matter what type of shoe. I bought this for my sister who is in a cam walking boot.  I am sorry I didnt believe the negative reviews. This item should not be sold on Amazon period.
