How are shoe sizes not yet standardized to some sensible units? I’d understand if it was just the US being behind on QoL as always, but even Europe has some weird-ass system.

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).
