European shoe size conversion is easy. European shoe sizes are unisex, compared to the US standard which clearly separates men, women, and children’s shoe sizes. In the European shoe sizing standard, the color, and details often identify whether the footwear is for male or female. European sizing can extend up to a size 50, which measures 12 ⅔ inches.
How to convert Euro shoe size to US? What is a size 40 in US? To convert a European shoe size to its equivalent in the US, it’s important to note that there is no set conversion formula, as the differences can vary slightly. Example: If you are wearing a US men’s size 9, then in EU terms, your size will be 41.5 in Euro, while a US size 11 would correspond to a European size of 44.5.
European shoe sizes are measured in centimeters. Just like US shoes, though, the number does not correspond directly to the size of the shoe – a size 44 in the US will not be 44 centimeters long, but will in fact be about 27.9 centimeters or 11 inches in length. The most common sizes for women are size 39 (in US = 8), EU size 37 is 6.5 US, and size 38 in the US is 6.
