Use a blank piece of paper to trace and measure the child's feet.
To ensure accurate measurements, place the paper on the ground next to a wall and have the child stand with one foot on the paper with their feet shoulder width apart, heel pressed against the wall.
Trace the foot and repeat the process with the other foot.
Use a measuring tape to record the length of both feet and apply the longer of the two measurements to the size charts provided above.
