Good socks. They can extend for a foot size of 46. Although you can not choose colors and patterns, i am satisfied with the ones i got. It took more than a two and a half months to arrive, seller extended protection once. When that expired i asked for a refund, but a seller asked to be patient and thankfully the socks did arrive. The postal services were in chaos because of 11.11 and New Year so i guess it wasn't entirely fault of a seller it took so long to arrive.
low % of cotton... fix it
