Foot length and how to measure
On Nike's charts, a men's 3.5 fits a foot 21.6 cm long and a women's 3.5 fits 20.8 cm.
Where a maker prints a foot length, a men's 3.5 runs from 21.5 cm at New Balance to 23.3 cm at Dior.
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.
