Foot length and how to measure
On Nike's charts, a men's 4.5 fits a foot 22.4 cm long and a women's 4.5 fits 21.6 cm.
Where a maker prints a foot length, a men's 4.5 runs from 22.4 cm at Nike to 23.5 cm at Converse.
For a women's 4.5 it runs from 21.5 cm at New Balance to 22.3 cm at Valentino.
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.
