Why are shoe sizes different in different countries?
Feet are measured quite differently in the US versus Europe. The US shoe sizes are based off of barleycorns, which are roughly 1/3 of an inch (around 8.47mm). European shoe sizes rely on Paris points, which equate to 2/3 of a centimeter (or 6.67mm).
