Our sizing is unisex, please refer to our size conversion charts to find your respective US, Euro, and UK shoe sizes. You should purchase your UGGs true to your everyday shoe size. (Please ensure you read the size & fit tab on the product page as this may vary depending on style)

Please note since our sizing is unisex, all men’s boots & slippers will be tagged with the UGG size, rather than their US size, so don’t be alarmed by this.

Boot Sizing: Your new sheepskin boots should be a snug fit. With continued use, the wool will adjust to the shape of your feet, creating a perfect fitting UGG boot. 

Slippers: For our Slippers and slides, we recommend reading the size & fit section of each product before purchasing as you may need to size down due to the particular styles. 

Slides: Due to the style of our open-toe Designer Sandals, we recommend choosing your ordinary AU/US/EU size, and this will automatically convert to a size down in our UGG sizing. If you prefer an extra snug fit, you could choose to size down in your ordinary AU/US/EU size, which will then convert to two sizes smaller in our UGG sizing.

If you’re not sure of your usual shoe size (or just want to be extra safe) we recommend that you measure your foot from the tip of your longest toe to the back of your heel and refer to our size chart to see which size corresponds with the length of your foot. Alternately, you can download our At-Home Size Guide to find your perfect fit.
Our printable size chart is measured by UGG sizing, so men should use the UGG size as seen on the sheet, and women can use the UGG sizing as equivelant to AU/US sizing.

Measure your feet in the afternoon, when feet tend to be their largest. Some people have one foot slightly larger than the other. Measure both feet and choose the size that fits the larger of the two.

Genuine UGG boots are meant to be worn without socks. Wool will naturally wick away moisture and allows air circulation to keep your feet dry. If you prefer to wear socks, select cotton socks or another natural fibre. You can read more about this here. 

Bonded boots (e.g. Denim, Camo) are a small fit and will only stretch slightly. If you prefer a looser fit then we would recommend selecting one size larger than your normal fit.
