I ordered one set of these socks that I am still wearing. I liked them so much that I ordered a second set, but the black socks from that set almost immediately got holes in the toe area. I'm not sure if they were from a different factory or what the problem was. Overall, however, I do like the style and fit of these socks, and they (usually) stay put under sneakers or other shoes and maintain a low profile. I like the assortment of colors so that I can coordinate them with shoes in case a little big of the sock edge peeks through. I wear a size 10 shoe, regular width, and the Large size sock is a good fit.
