Find Your Perfect Fit with Lunar Shoes
Choosing the correct shoe size can make all the difference in comfort — whether you’re picking everyday trainers, stylish boots or seasonal sandals from Lunar Shoes. Our footwear follows UK to European (EU) sizing standards to keep things simple and consistent.
We do not offer half sizes, and sizes range from UK 3 to UK 8 (EU 36–41).

Why EU & UK Sizes Matter
Most footwear brands in the UK and Europe label shoes using European (EU) sizing, which differs slightly from UK sizes. The systems are based on different foot length measures and last shapes — so using a dedicated conversion chart helps you choose the correct shoe with fewer returns and better comfort.
Tips for the Best Fit
-
Lunar Shoes run true to UK sizes — follow the chart above when ordering.
-
If you’re between sizes, consider the style (sandals vs trainers vs boots) and sock thickness.
-
No half sizes means you may prefer to size up if you’re unsure.
-
Comfortable fit = a thumb’s width of space at the toe and snug heel support.
