Okay well I have 4 stars because these are the best socks ever, infact, I threw out all my other socks and switched to just these. No show and they never slip. THE PROBLEM NOW, all the pairs I ordered before had a white symbol, and every time I buy more they have the grey and they are not as low show as my others… I wanted to simplify life and have all the same kind, no matching of colors or slightly different shape, but 4 times now I’ve ordered white symbol and gotten thicker longer ones with gray symbols. I’m considering switching all of my socks to the gray…. But the white symbol ones are way better, they don’t show with hey dudes on and gray symbol ones do now. I’m at a loss. Can someone tell me where to buy 100 pairs of white symbol so I never need to buy another sock again in my life?
