AW 136 Women's Microfiber Knee High Trouser Socks 20-30 mmHg

Looks like a good product I would definitely recommend that you size up

Microfiber knee socks--maybe size up

The microfber socks are good for a less "sporty" or casual look, eg for work. However, the width of the sock from heel to front of ankle seems unusually tight, leaving purple marks on my ankle. I went from my usual S to M which improved the situation, especially after I had worn the socks a couple of times. However the "compression" effect might be compromised with a larger size. (I am on the large end of S, but not up to the sizing dimensions of M. )

Too small and we used the size guideline provided
