Frequently asked questions
Why are US men's and women's shoe sizes different?
US men's and women's shoe sizes are offset by about 1.5 sizes on the same last (foot mould). A women's US 8 is roughly a men's US 6.5. This means men and women can share EU or UK sizes more easily than US sizes, since EU sizing is based on foot length in centimetres and does not have a gender offset at the same size number.
How do I measure my foot to find the right size?
Stand on a piece of paper, trace your foot, and measure from the heel to the longest toe in centimetres. Add about 0.5-1 cm for comfort. Match that measurement to the CM column in the chart above. Do this in the afternoon - feet swell slightly through the day and are largest then.
Why does EU sizing seem more consistent?
EU (Continental) sizing is based on Paris points - each point is ⅔ of a centimetre. Since it is rooted in physical foot length rather than an arbitrary scale, it is the same for men and women and consistent across most European countries. UK sizing uses a different point system (⅓ inch per size) but also has no gender offset, making it similarly consistent.
What is the difference between UK and US sizes?
For men, UK sizes are about 0.5 sizes smaller than US sizes (US 10 = UK 9.5). For women, UK sizes are about 2 sizes smaller than US sizes (US 8 = UK 6). Children's sizes align more closely, with UK sizes running about 0.5 sizes behind US sizes.
