Nine West Fishnet Trouser Sock

Well, it has officially turned too cold to go barefoot in my heels when wearing pants. What do you do when the winter makes it hard to keep tootsies toasty and footsies fashionable? I've always been a fan of the trouser sock, which has seemed somehow cooler than the knee-high. Like this fishnet Nine West trouser sock, you won't find that on any grannies I know, but maybe your granny is cooler than mine? Word to the wise/cheap, I got a three pack of Nine West trouser socks at Marshall's for $6, less than half the original price you'd pay at a department store.
