I'm leaving this here in hopes of helping someone else because I couldn't find this information anywhere. Even contacting the manufacturer couldn't point me in the right direction. Hot Sox children's socks are available in sizes S/M and M/L. Size S/M (sock size 4-7) is suitable for children with shoe size 10-13 and size M/L (sock size 8-9.5) is suitable for children with shoe size 13-3. Size S/M would probably fit around age 3-6 and M/L would probably fit around age 6-9. The socks are all adorable and colorful. One star deducted for unnecessary size confusion.
