Shoes
All ages in the chart are approximate. For length, our chart uses the measurement of the foot rather than the shoe. First, measure the length of the foot while standing and wearing the socks that will be worn with the new shoes. Then, take the length measurement and find the corresponding U.S. shoe size in this chart.
