Your sock size is US 10.0 (Small / Medium (9-11)).

  • Your foot is about 26.0 cm (10.24 in) long, which maps to US sock size 10.0.
  • In EU sizing that is approximately size 39, and in UK sizing size 9.0.
  • Most sock packaging labels this as "Small / Medium (9-11)." When a label shows a range like "9-11", it means feet up to 11 inches long will fit without stretching.

Next stepWhen buying compression socks or therapeutic hosiery, also measure your ankle and calf circumference, because those garments are sized on width as well as length.
