Just ordered 3 pairs of these. I love that they come in 2 sizes. I am on the border between the 2 sizes and am constantly frustrated by knee socks that only go 3/4 of the way to my knees. These socks are perfect. In fact, I am ordering many more. Wish they came in a dark grey and navy too. I wore them all day and there was no binding marks left behind when I took them off. Additionally, they stayed pulled up all day. super comfortable, not too thin, nor too bulky.
These socks do fit snugly, maybe even a little tightly at the knee, but I was not conscious of that when wearing them. They are thin enough to go under boots but still substantial, and well-priced.
I wanted a true kneesock, not a thin trouser sock, to wear on an upcoming visit to a cold climate. These kneesocks fit the bill perfectly! They very soft and the right height. They are not tight at the top, but they stay up.
