You must pay attention to the size when buying shoes for your children, because the shoes you buy may be too small if you don't pay attention. We divide children from birth to 18 years old according to their age into four periods: big, small, toddler, and baby. In order to make it clearer, each period has been expanded.
From the shoe size chart below, you can see the shoe sizes from the newborn to the 18-year-old. These sizes include US/Canada, UK size, EU(European) and Japanese sizes, as well as lengths in centimeters and inches. You may see multiple lines listed for the same shoe size. That's because the length of men's shoes and women's shoes of the same shoe size is different. Due to the measurement methods and raw materials of different regions and manufacturers, as well as some other differences, the actual length under the same size may be different, so this chart can be used as a reference for buying shoes.
