Travel Blue's compression socks, such as those shown, generally do not require specific measurements in centimetres for ankle and calf, as they are designed to fit a range of sizes. However, for a better match, it is important to follow the manufacturer's sizing guidelines, which are usually based on foot and heel measurements.

For Travel Blue's travel compression socks, sizes are indicated as S/M, which cover a standard size range without the need for specific ankle and calf measurements in centimetres.
