How accurate are international shoe size conversions?

Charts give a reliable starting point, but sizing differs by brand and shoe style. For the best fit, measure your foot length in centimetres and match that column.

What is the difference between US men and US women shoe sizes?

US women's sizes run about 1.5 sizes larger than US men's for the same foot, so a US Men 9 is roughly a US Women 10.5. This tool shows both.
