Standard metric foot sizes can be converted to the nearest Paris point (2 ⁄ 3 cm) sizes using approximate conversion tables; shoes are marked with both foot length in millimetres, as for pointe ballet shoe sizes, and last length in European Paris point sizes (although such converted Stichmaß sizes may come 1 ⁄ 2 to 1 size smaller than ...
