I have these in many colors and intend to purchase even more. I've never before had knee socks that fit my plus legs. These are a comfy fit. calves were 18" when I got my first pair about 2 or 3 years ago now, recently lost some weight and now calves at 16". Fit is still very similar. The description says up to 23" but I can't imagine these socks would fit a leg above 20" without cutting off all circulation. They stretch because they are knitted, so they are shorter the wider you stretch them. I usually wear pants in a 34" or 35" inseam, and they come to about 1.5 inches below the bottom of my knee cap. Up to the knee cap if I layer them over compression leggings in the colder months. They are warm. They're not soft, so I wouldn't recommend them to anyone with sensory sensitivity to rough materials. They wash and dry well, color has not faded in any pair. I have noticed that 2 pairs have elastic threads coming loose from the roll top elastic bunch, but not in a way that affects the socks' structural integrity.
