Measure your foot length in centimeters or inches, then enter it below to find your exact size.
💡 Tip: Measure your foot at the end of the day when feet are slightly larger. Stand on paper, trace your foot, and measure the longest distance from heel to longest toe.
Shoe sizing is one of the most inconsistent measurement systems in retail, there is no universal standard, and the same size number means different things in the US, UK, and European systems. A US men's size 10 is a UK 9.5, a European 43-44, and a Japanese 28 cm. A US women's size 8 is a UK 6, a European 39, and a Japanese 25 cm. Getting this wrong on an online purchase almost always means a return. The most reliable approach for international online shoe shopping is to measure your foot length in centimeters and match it directly to the brand's centimeter size chart rather than converting size numbers. Stand on a piece of paper, trace your foot, and measure the longest distance from heel to toe. Most brands publish foot length ranges for each size, matching by measurement eliminates the ambiguity of numeric conversion. Half sizes are another complication. Not all international sizing systems have half sizes. European sizing uses whole numbers only, an EU 42 fits foot lengths from about 26.5 to 27 cm, covering what would be a US 8.5 to 9. If you're between sizes, always go up rather than down in shoes, a too-tight shoe causes more discomfort than a slightly roomy one, and most shoes accommodate minor sizing differences with insoles.
Shoe sizing varies significantly between countries and even between brands within the same country. The US, UK, and EU systems all use different scales, and men's and women's sizes in the US don't correspond to the same foot length. Understanding these differences is essential when buying shoes online from international retailers.
US sizes are based on the barleycorn, an old English unit of 1/3 inch (8.47mm). Each US shoe size represents one barleycorn increment in foot length. Men's and women's US sizes are different scales, a women's size 8 US corresponds to a men's size 6.5 US for the same foot length.
EU sizes (also called Paris points) are based on 2/3 centimeter increments. EU sizes are unisex, though men and women may have different fit preferences in the same EU size due to last (shoe form) differences.
UK sizes are similar to US sizes but offset by approximately 0.5 for men and 2 for women. A men's US 10 = UK 9.5. A women's US 8 = UK 5.5.
