Measure your baby's foot from the back of the heel to the tip of the longest toe, then pick the size that matches the foot length. Age ranges are only a guide, since every baby grows at their own pace. For chubby feet, add about 0.1" (3 mm) to your measurement.

How to measure

  1. Stand your baby on a sheet of paper (or hold the foot flat against it if they are not standing yet).
  2. Mark the back of the heel and the tip of the longest toe.
  3. Measure the distance between the two marks in inches or centimeters.
  4. Choose the size whose foot length is equal to or just above your measurement.
