For all over-the-calf socks and calf sleeves, your sock size is based primarily on your calf circumference at its widest point. Use shoe size as a secondary reference point. If you are between sizes, we recommend you size up unless you want a tighter fit, in which case, you should size down.
For all below the calf socks, your shoe size is the primary determinant of size. For your convenience, you can find size charts for all socks here. Size charts for knee, ankle and elbow sleeves are found on the corresponding product page.
IMPORTANT: If you have any doubts about selecting a size, please email us and we'll help you select the right size for you.
