Children’s Footwear Size Conversion Chart
Unlike adults, children’s shoe sizes are the same regardless of the gender. The scale children’s shoes use is actually the same for men. In other words, a child’s size size 7 is the same as a men’s size 7, and equivalent to a woman’s size 8 or 8½.

Brand Specific Size Charts
Different brands use different sizing. One company’s size X might not be another’s size X, and trying to convert them to U.S. sizing only compounds the problem. While nothing can replace actually trying on a pair of shoes to find the best size, the following charts are better than wildly guessing.
