Not medical grade silicone!
These gel pads are not real medical<br />Grade silicone heel cups. I own several authentic medical grade silicone ones already so I know the difference.  I should have known by the price that these could not have been authentic medical grade silicone. There is a big difference in softness and pliability between 100% silicone and ones that are just plain gel. Do not buy these if you want real 100% silicone. These are just your average gel heel cups made to look like silicone ones.
