I've recently taken to savaging my socks with a pair of scissors. I'm type 2 diabetic, and so have to take special care of feet, including ensuring they receive a good blood supply. Nearly all socks I put on tend to create a groove around my leg, from unnecessary elastic, which I assume doesn't help blood supply at all. So I cut a line straight down the back of the socks, for about an inch, until I seem to have got past the elastic gripper. May look odd from behind when wearing shorts, but who cares....?
