Mondopoint

Mondopoint sizes a shoe by the foot it fits, in millimeters. A Mondopoint 265 shoe is made for a foot 265 mm long, heel to longest toe. There is no starting point to remember and no allowance to add: the room inside the shoe is the maker's business, and the number is the foot. A full Mondopoint marking can also give the foot width in millimeters.

It is widely used for ski boots. Japanese shoe sizes follow the same idea in centimeters: a 26.5 cm foot is a JP 26.5.

On a size chart

The barleycorn and Paris point scales describe the shoe, counted from a fixed start. Mondopoint describes the foot. That makes it the easiest system to measure for: a shopper with a sheet of paper and a ruler knows their size.

A chart that lists foot lengths is most of the way there. Ruban Size's Shoes template puts the foot length beside each size:

Its 25 cm row is a 250 mm foot. Say on the chart whether a length is the foot or the insole: the two differ by the toe room.

In Ruban Size

Find my size for shoes works from the foot, the Mondopoint way: it asks for the foot length, in cm or in, and compares it with the chart. If the chart lists insole lengths instead, it keeps the toe room, 1.5 cm for a regular fit. The JP size in its "Usual equivalents (approximate)" line is the foot length in centimeters, rounded to the half. How to measure your foot length and width has the steps.
