Andie Kids Rain Boot

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 (this isn't always the big 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 0.4 inches (1 cm) shorter, so the inner sole is the same length as their foot or very slightly longer. Andie Kids inner soles run from 5.35 inches (US 5) up to 9.06 inches (US 4, the largest kids size).

Yes, Andie Kids fit true to size. If your child's foot length falls between two sizes, measure their foot and choose the size where the inner sole is about 0.2 to 0.4 inches (0.5 to 1 cm) longer than their foot. The inner sole length for each size is in the chart above. 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. You can compare this to the Width inner column in the chart above. Andie Kids are made to a standard width. The natural rubber and neoprene lining will soften and mould to your child's foot with wear, so a slightly snug fit at the start is normal.

Neither by default. Measure your child's foot first. The right size is the one where the inner sole is about 0.2 to 0.4 inches (0.5 to 1 cm) longer than their foot (use the inner sole length column in the chart above). For growing feet, that little bit of room helps the boot last longer before it's outgrown, as long as the heel doesn't slip when they walk. The neoprene lining will soften and mould to your child's foot over time like memory foam, so a slightly snug start is normal.

Go with the size that fits your child's larger foot. If the difference is significant, you can remove the inner sole on the larger side for a little extra room, or add a thin insert on the smaller side for a snugger fit.
