I ordered a size 4-10 and received a size 10-13. These socks are very thin without padding and elasticity. I'm guessing they won't last more than a month or so before fully stretching. The toe seam touches the front of the toe, not the top of the toe like most socks do. So if you are concerned this is not for you. I am a woman and I wear size 11 shoes, these socks barely fit my foot. I would rather say that these are nicer children's socks that don't need to last very long, but for an adult they can last a season.
