Size Chart - Kids

Are you strugglin to find your child’s ideal shoe size? Whether your child’s shoes don’t fit quite right or you just want to double-check that you’re buying the right size, we’ve created the chart below to eliminate any confusion. Our chart allows you to find any kid’s shoe size in inches and cross-reference it with conventional U.S. sizing conventions. It covers infant, child, and youth sizes.

How to Measure

If you want to know how to measure your kid’s shoe size accurately, just do the following:

  1. Trace a line around your child’s barefoot using a sheet of paper and a pen.
  2. Measure the full length of the foot from heel to toe.
  3. Use the measurement (in inches) to find your child’s corresponding U.S. kid’s shoe size in inches on the chart below.

So, for example, if the child is 7 years old and the foot measures 8.5 inches in length, the child would fit best in a youth size 3 shoe. Of course, kids’ shoe size measurements are not always exact. So if you purchase a pair of orthopedic children’s shoes at HealthyFeetStore.com and they don’t fit as well as you’d hoped, you can exchange them as many times as you need to — completely free of charge!

Other Factors Influencing Kids’ Shoe Sizes

Kids’ shoe size measurements are not just limited to length. If you want to ensure maximum comfort, you have to consider the width as well. If the length is right, but the shoes still feel snug, refer to our shoe width measurement chart to determine how to find the optimal width.
