Enter your US shoe size to see UK and EU sandal sizes.
This sandal and flip-flop size converter converts US sandal sizes to UK and EU for men and women. Sandals and flip-flops use the same shoe size system as regular shoes — there is no separate sandal sizing standard. The main considerations are that feet swell in heat, and strappy sandals may feel tighter than shoes at the same size. Havaianas uses Brazilian sizing with paired ranges and is the notable exception to standard sizing.

Frequently Asked Questions
Do sandals run true to size?
Generally yes. In very hot weather when feet swell, half a size up can prevent straps from becoming tight. If you are between sizes, size up.
Are flip-flop sizes the same as shoe sizes?
Yes — flip-flops use the same US, UK, and EU sizing as regular shoes. The size represents the same foot length.
How does Havaianas sizing work?
Havaianas uses Brazilian sizing sold in size pairs (e.g. 37/38). US women's 7–8 is roughly Havaianas 37/38. Use the Havaianas chart above, and if you fall between two pairs, choose the larger one.
Do men and women wear the same sandal sizes?
No — the same US size number fits a different foot length for men and women. A men's US 8 and a women's US 8 are different sizes. Use the separate charts above.
Should I size up for sandals in summer?
Only if you are between sizes or know your feet swell significantly in heat. Otherwise, your regular shoe size is correct.
