I can't decide if this is more smart or more nutty, but I had to share. They're socks with an opening on the top of your foot so they don't show if you're wearing flats or pumps with jeans.
LOL! Those make me laugh for some reason. I can definitely see a market for them though. I prefer to wear my flats sockless, but I know a lot of people don't like it. That would be a solution, as long as your jeans don't ride up when you sit.
