* Official Stan's Shoes conversion guide — EU sizing uses no half sizes; UK sizing runs smaller than US.
* Women: UK = US − 2.5. Men: UK = US − 0.5.
* EU sizing is used by Birkenstock, Dansko, ECCO, etc.; UK sizing by Hartjes, Gabor, Hassia, etc.
* UK-sized comfort brands often fit more generous — if between sizes or narrow-footed, size down.
* Removable footbeds make many UK & EU shoes great for orthotics. Fit varies by brand — check the product page.
