I tried them on, felt comfortable for a few hours, then I started feeling the shivers through the pillow, the outer ring is hard plastic, all the weight is on it, there are 2 holes in the middle of the soul with no support and you feel it actually at the ankles and heels. If they give support everywhere it would be good to try gel inserts but I won't be buying them again. It's a shame because I liked them but you get what you pay for
