Hi. I love the socks. Ankle and knee high compression. As you can see I’ve got a lot. I do admit according to the size guide (I wear 9 ladies) I require size s/m. I find the ankle compression almost too snug and usually just wear them when I’m finally relaxing. ( I don’t wear them with sandals) The knee highs are okay but I have not worn a lot of them yet. I have ordered some M/L and they seem to be better. Is there a chance that I could return unworn sizes S/M For ML.? I am from Canada! Thanks for listening. Just read your refund policy after the fact and you don’t exchange or refund. I’m sure I can gift some of these.
