Before I bought these socks I called this company. I told them that I wear a size 12 shoe and they said the extra long sticker sox would work for me. I asked about them for my brother, who wears a size 14 shoe and they said it would small on him. They were right both times. The sock is a good fit for me, but was too small for my brother. I gave 5 stars because everything I was told turned out to be true. Good customer service. Nice socks.
