How do I convert Nike shoe size to UGG?

Match by foot length in centimeters on each brand’s chart. Example: Nike US 10 ≈ UGG US 10.0 (about 27.1 cm). Model fit can still differ — check model guides.

Is a Nike US 10 the same as a UGG US 10?

Not always. Labels can map to slightly different foot lengths. Use the cm column, then adjust for the specific model’s fit.
