Compression socks for nighttime (sleeping) use. I ordered the wrong color. I tried them on once, but they are not the color I wanted, so I am selling them. Size: S Please refer to the size chart in the second photo. They extend from above the knee to the middle of the thigh. You can wear them without them slipping down when you wake up in the morning. The light compression allowed me to sleep comfortably. Please refer to the third photo for the compression level. I have washed and stored them at home. Please purchase with the understanding that they are used.
