US 11.5 in every system

Foot length and how to measure

On Nike's charts, a men's 11.5 fits a foot 28.3 cm long and a women's 11.5 fits 27.5 cm.

Where a maker prints a foot length, a men's 11.5 runs from 28.3 cm at Nike to 30 cm at Converse.

For a women's 11.5 it runs from 27 cm at Veja to 28.5 cm at Dr. Martens.

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.
