Fruit of the Loom Cool Zone No-Show Liner Socks for Women, White Assorted, Sizes 8-12 (6-Pack)

These stay on pretty well without sliding down into your shoes. I've only had one slide down into my shoe, but it was because I had on slip on tennis shoes, and when I forced my foot down into the shoe, the sock was a little bunched up. Other than that one time, they have been great.

I have a severe skin infection on my ankle and wanted something to go on my feet under my slip-ons. These fit perfectly without touching any part of my ankle or the skin around it. I found them to be quite comfortable and soft. I wear size 8 shoes and ordered the size range 8-12. The smaller size (4-10) would most likely have been too snug--as these were just snug enough to stay on and in place. They really were comfortable enough that I forgot that I was wearing them--and my skin is very sensitive to the touch because of the infection. I would definitely buy again.
