Foot length and how to measure
On Nike's charts, a men's 4 fits a foot 22 cm long and a women's 4 fits 21.2 cm.
Where a maker prints a foot length, a men's 4 runs from 22 cm at Nike to 23 cm at Converse.
For a women's 4 it runs from 20 cm at Crocs to 22.3 cm at Golden Goose.
To measure, stand on a sheet of paper, mark your heel and the tip of your longest toe, and measure between the marks. Do both feet and use the longer one.
