A fair chunk of those posts seem to be either thighhighs or kneehighs that are mistagged or not tagged at all. I don't believe we have a kneehighs pull tag either. Personally I wouldn't mind using sock pull as a catch-all tag for thighhighs kneehighs and socks, especially for posts where it's difficult to discern the length due to loose socks (not to be confused with loose socks) or stretched socks, such as post #710039 or post #779078 (explicit).
Either the tag needs cleaning before implication or we combine sock pull with thighhighs pull and drop the implication.
