What does this tool do?

Shoe sizes are based on different starting points and steps in each country. UK men's sizes are usually half a size below US men's, while UK women's are about two sizes below US women's.

Foot length in centimetres is the most reliable way to compare. Measure from heel to longest toe in the evening, when feet are largest.
