NIKE Kids Size Chart
The sizes offered for Nike Kids shoes are based on the US sizing system. The label inside of each shoe includes US sizing information, as well as UK, Europe, and CM values. The chart below is information presented on the label inside of Nike Kids footwear.
There is no difference between boy's and girl's footwear sizing. If you do not know which shoe size is appropriate, you may want to measure your foot.
Note: C = Child sizing (infant, toddler, preschool) Y = Youth sizing (grade school ages)
