These are very small. I ordered large and they were not. And they shrink after washing. (Only washed one of the 3 pairs and it was about an inch shorter after washing than the new unwashed ones) The rubber on the bottom sticks to some of the rugs and on tile floor which actually tripped me (and I got them to prevent falls from slipping!) They do not come up high enough on the ankle (besides being small and tight on the foot) so they come off and roll down your heel. I'm sure I'll find some use for them, but not on my feet. Washing the car?
