Foot length and how to measure
On Nike's charts, a men's 15.5 fits a foot 31.7 cm long and a women's 15.5 fits 30.9 cm.
Where a maker prints a foot length, for a women's 15.5 it runs from 30.9 cm at Nike to 32 cm at Salomon.
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.
