How do I convert TOMS shoe size to On?

Match by foot length in centimeters on each brand’s chart. Example: TOMS US 10 ≈ On US 10.0 (about 27.2 cm). Model fit can still differ — check model guides.

Is a TOMS US 10 the same as a On US 10?

Not always. Labels can map to slightly different foot lengths. Use the cm column, then adjust for the specific model’s fit.
