The Andie Kids range is sized in UK numbers. Use the inner-sole length and other key measurements below to find the best fit. Measure your child's foot and choose the size where the inner sole is about 0.5 to 1 cm longer than their foot, so there's a little room to grow without the heel slipping.

Have your child stand with their weight evenly distributed across both feet. Place a ruler or measuring tape against a wall and measure from the back of their heel to the tip of their longest toe. Measure both feet and use the longer measurement when choosing a size. If your child usually wears thick socks with their boots, measure with the socks on.

Use the inner-sole length column in the size chart above. Match your child's foot length to the inner-sole length for the size you're considering. Their foot should be the same length as the inner sole, or up to about 1 cm shorter, so the inner sole is very slightly longer than their foot.
If your child's foot length falls between two sizes, measure their foot and choose the size where the inner sole is about 0.5 to 1 cm longer than their foot. A little growing room is fine, as long as the heel still sits in place when they walk.
Measure across the widest part of your child's foot, around the ball of the foot, with their weight on the foot. Compare this to the Width inner column in the chart above.
Choose the size that fits your child's larger foot. If the difference is significant, you can use a thin insert on the smaller side for a snugger fit.
