- shoe size (man) = 3 × last size in inches - 24
- shoe size (woman) = 3 × last size in inches - 22 1/2

- shoe size (man) = 3 × last size in inches - 25

- shoe size = 3/2 × last size in centimeters (cm)
- The size of the last is defined as 1.5 - 2.0 cm larger than size of the real foot, so the formula for shoe size using foot size is:
shoe size = 3/2 × (last size in centimeters + 1.5 cm)
- shoe size = 3/2 × last size in centimeters (cm)
