When sizing boys' boots, measure both feet at home using a ruler and consult a size chart, considering room for growth to ensure a comfortable fit. Unlike some other types of boys’ shoes, boots tend to flex less, so it’s important to consider the length as well as the width of your child's feet. Some brands offer different width options, such as narrow, regular, or wide. If your child has wider feet, look for boots that provide a wider fit to ensure comfort and proper foot development.
Children's feet can grow quickly, so leaving some room for growth is generally recommended—opt for the size up. Ensure room for big socks if they’ll be wearing them in the winter, and, in general, aim for about a thumb's width of space between the end of the longest toe and the front of the boot. The sides of their feet should lightly touch the inner sides of the boot without feeling any pressure.
When buying from Etsy shops in the United States, boys' boots use a “big kids shoe scale”’ ranging from one to seven, while toddler boys’ boot sizes use a scale from one to 13. If you’ve fallen in love with a style from a European designer, you’ll notice an “EU” beside a number ranging from 20-26 for toddlers and 27-39 for boys. The United Kingdom uses its own scale, while other shops may use inches or centimeters to determine the length of the shoe.
