How To Measure Their Foot
Grab a piece of paper, a pencil or pen and a ruler to measure the length of their foot.
Place the piece of paper right up against a wall, with their heel also up against the wall on top of the paper.

Tracing Their Foot Shape
Next, trace the previce shape of your baby's foot. Make sure their toes are pointing out straight, not curled.
While tracing, ensure your writing utensil is pointing vertically and not at an angle.

Recording The Measurement
Once you have traced their exact foot shape, measure the length of the tracing. Ensure the ruler is straight (as seen in the above image).

 

There you have it! Now select your size from the size guide.
