Understanding Shoe Size Systems
US Shoe Sizes
The US sizing system is the most common in North America. Men's and women's sizes differ — a women's size is typically 1.5 sizes larger than the equivalent men's size (a men's 9 = women's 10.5). Half sizes are standard.
EU Shoe Sizes
European sizes use the Paris Point system, where each size equals 6.67mm. EU sizes are unisex — a 42 is a 42 regardless of gender. The scale typically runs from 35 to 50.
UK Shoe Sizes
UK sizes are similar to US sizes but offset. Men's UK sizes are about 0.5-1 size smaller than US (US 10 = UK 9). Women's UK sizes are about 2 sizes smaller than US women's.
Frequently Asked Questions
Our converter uses official brand size charts to map sizes between brands. While no converter can account for individual model variations (a Nike running shoe fits differently than a Nike basketball shoe), our conversions are accurate for standard sizing across brands.
It depends on the brand. Converse runs about 1 size large (size down). Nike running shoes run slightly small (size up half). Our converter handles these differences automatically. Check the fit note on each brand's size chart page for model-specific advice.
