Several of my "hacks" actually involve hacking (i.e. cutting) things.
This hack works for knee socks whose top elastic band is somewhat too tight. It can also help if the socks are a little too short. But if the elastic is very tight, this probably won't help enough. If the elastic isn't too tight to begin with, then doing this may make them too loose.
Many knee socks nowadays have the top elastic band made of an elastic section that's been folded over and knit together on the inside, so that it's two layers of elastic fabric. With this kind of sock, it is easy to cut open the seam where it's knit together, thereby changing it into a single longer layer of elastic.



Right leg: original sock. Left leg: hacked sock.
