Women's size guide

Australian shoe sizes are equal to American shoe stores, so if you're purchasing footwear from a US-based retailer, you should find the fit is the same.

If you're buying from a UK-based store, go down two sizes. If you're a 7 in Australia, you're a 5 in the UK.

Men's size guide

Australian men's shoe sizes are equal to shoe sizes in the UK.

If you're shopping from an American store, you'll need to go up one size to get the right fit. So, if you're a 9 in Australia, you'll be a 10 in the US.

Baby size guide (pre-walking)

Baby shoe sizes are the same in Australia as they are in the UK. They are one size smaller than American shoes.

If you're buying from a store that uses Japanese sizes, the shoe size is roughly the same (but slightly higher) than the length of the foot. For example, if your baby's foot is between 99 and 104, a size 10 should fit.
