UK vs US Shoe Sizes
UK and US shoe sizes are closely related but not identical. For men, UK sizes are typically 0.5 to 1 size smaller than US sizes (a UK 9 is roughly a US 9.5-10). For women, the difference is about 2 sizes (a UK 6 is roughly a US 8).
Both systems use a similar incremental scale with half sizes, making conversion relatively straightforward. However, exact conversions vary by brand. Use our shoe size converter for brand-specific accuracy.
