UGG Sizing Info
UGG Australia Sizing Guide
If you are unsure which shoe size to purchase, please follow the following steps:
- 1. Draw a straight line, longer than your foot, on a piece of paper.
- 2. Place the paper on a flat surface. Stand on the line with your heel and longest toe centered on the line. If measuring a child's foot, it may be easier to hold the paper up to their foot.
- 3. Place a mark on the line at the tip of the longest toe and at the back of the heel.
- 4. Repeat steps 1-3 for the other foot.
- 5. Measure the distance between the marks. Taking the larger of the two measurements, use the conversion chart to find your correct shoe size.
