How to tell crocs size?

[Ladybird69]

There are 2 numbers on the bottom of the crocs. Theres a No 7 and a No 9 so how do I find out the size? Tia

The one on the left (the smaller one) is the UK size. I’m a UK 8 and mine have 8 and 10 on.

Thanks @PauliesWalnuts so mine at uk 7. Great 😊

My Crocs slippers are my usual shoe size.

The higher number refers to US/AU women's sizing which is 2 numbers higher than men's (and UK unisex sizing).

Thanks all 💐
