Review (3/5): Different
These are a bit different to wear. I wear a size 9 1/2 women's shoe. I had no difficulty putting these on. They slip on like socks and rest just above my ankle point. The toe area is open from about midway down my foot (about where the center of my foot is). I didn't find these overly constrictive and I could sleep in them if desired. However, if you have oversized ankles or you have swelling issues in your feel you will need to be careful with these as you could easily cut off circulation.
The gel pad is in the heel and it is extremely comfortable and soothing on your feet. After wearing overnight my heels felt extra soft.
