How the conversion is matched
This comparison aligns the Japan/CM entries in UGG’s separate women’s and men’s charts. For example, women’s US 8 and men’s US 7 both list 25 in that column. Their EU labels differ: women’s US 8 is EU 39 and men’s US 7 is EU 40.
These chart pairs are a starting point, not a universal promise of fit. UGG’s heel-to-toe entries are not identical for every paired row, and men’s and women’s models may have different shapes. Check the specific product before ordering.
Model and half-size availability
A half size shown in a general size chart may not be sold in every boot, slipper or shoe. Follow the sizing advice on the product page for the model you want.
For the best fit, always refer to the specific size chart for the UGG model you’re interested in or try on the boots when possible.
