Footwear - Conversion of sizing systems
1 Scope
This standard comprises three shoe size conversion tables covering the major shoe sizing systems (Mondopoint, European and United Kingdom, as well as China, Japan and United States). The tables are based on measurement of foot length, this being the logical starting point for any shoe size marking system. The tables contain the following information:
Table 1: Adults' technical shoe size conversion;
Table 2: Adults' recommended shoe size marking (simplified);
Table 3: Children's size conversion.
Explanatory notes are given in Clause 3.
Note: It is acknowledged that, due to the different ways in which each system has been developed and interpreted over many years without being formalized into any national or international standards (other than ISO 9407), there is no exact solution to the problem of accurate shoe size conversions. Tables 1 and 2 offer a good compromise solution which will, if adopted, benefit the consumer.

3.1 General
There are three main sizing systems (Mondopoint, European and UK). As there are fundamental differences between them, they have been aligned to a common denominator: foot length. Foot length is deemed to be the key reference point when fitting footwear. Customers' foot length can be readily measured and shoes marked with a designation that indicates the appropriate shoe size that will accommodate their foot length. Customers expect to buy the same size of footwear irrespective of the footwear type or style.
Note: To check that size marking is correct requires a practical fit assessment of footwear whereby subjects having appropriate foot lengths for the marked size of the footwear and the available toe allowance is assessed for satisfactory fit. Some allowance for foot width may also have to be made. This standard, however, does not attempt to assess the overall fitting properties of footwear i.e. it does not cover width, volume, toe depth, etc.
