Size & Fit Guide
Ugg Boots have a different fit to other kinds of footwear. When choosing your correct ugg boot size we recommend choosing a bigger size than from your standard shoe size.This is primarily due to the thickness of the lambskin and the wool inside the boot, making it feel tighter than its size suggests. The fitting will change slightly when the boots are worn in. Sheepskin like other soft leathers tends to stretch after a certain period of wear. Therefore your ugg boots should feel snug during first wear, and over time it will start to mould to the shape of your foot. To ensure you have the best fitting for your feet, please refer to our size chart below.
When selecting women sizes on the website, please use the latter number of the Oz Natives Size, eg. if you want to choose size 4-5, you will need to select size 5 on the website.
