Overall, I was pleased with the additional barrier between my heel and my shoe.
I wore them for about a week and was initially able to achieve some relief from heel pain due to a heel spur. It would have been perfect for me but the heel was too shallow and unfortunately after about a week wearing the Happy Feet I had an odd reaction resulting in a blister about the size of a 5 cent piece on the top of my foot where the silicone had twisted and rubbed my skin.
