Questions
How do I convert women’s to men’s shoe sizes?
In US sizing, a men’s size is roughly 1.5 sizes smaller than the same women’s size, so a women’s 9 is about a men’s 7.5. Compare the foot length in cm in both charts to be sure.
What is a US size 9 in EU sizes?
A women’s US 9 is about EU 39–40, and a men’s US 9 is about EU 42, based on the Zappos conversion chart.
How do I measure my foot?
Stand on paper with your heel against a wall, mark the tip of your longest toe, and measure from the wall to the mark. Measure both feet and use the longer one.
Why do sizes differ between brands?
There is no single international standard that all brands follow. Use these conversions as a guide and check the brand’s chart, especially for shoes.
