The sizes of 31 size sneakers
The sizes of 31 size sneakers:

Sneakers size is most of the time determined in two ways:

  • by foot length: the size equals foot length in stiches (0.26 in);
  • by insole length: the size equals insole length.

Important: size 31 corresponds foot length of 7.4 (in) and insole length from 7.6 (in) to 7.8 (in).

The standard measurement unit of foot length is stich that is 0.26 in.

For example: for foot length of 7.4 (in) the size is calculated as 7.4/0.26+0.5 (in) allowance for free blood circulation.Measurements accuracy should be ±0.03 (in).
