Enter your US shoe size to see the UK equivalent.
This US to UK shoe size converter is essential when shopping at UK retailers like Clarks, ASOS, or Next, or when buying from brands based in the UK. US and UK shoe sizes both use barleycorn units (⅓ inch per size) but start from different base points — meaning they are never the same number for the same foot. US men's sizes are approximately 0.5 larger than UK, and US women's sizes are approximately 2 larger than UK.
