Baby & Toddler Shoe Sizes

Your baby’s feet are constantly developing and growing, so it’s important to buy shoes that are flexible, comfortable and supportive.

Before choosing a new pair of shoes, the first thing to check is the size of those little feet!

How to measure your baby’s shoe size

Stand your baby barefoot on a piece of paper and use a marker to gently trace around each foot. Print our size finder to make this easier.

Using a tape measure, measure the length from the heel to the tip of the longest toe.

For both our My Flexx and My Shoes collections, add ½ inch or 1.3 cm to your child’s longest measurement to allow room for growth, then use the sizing charts below to find the perfect size shoe for your baby or toddler.

For our My Kicks collection, add ½ inch or 1.5 cm to your child’s longest measurement.

Good to know: My Flexx, My Shoes, and My Kicks baby and kids shoes have unique sizing. Be sure to choose the correct size from the charts below.

How often should you check shoe size?

Kids’ feet grow quickly; some toddlers can gain a full shoe size in as little as 6 months! To make sure your baby’s shoes still fit properly, it’s best to measure their feet every 2 to 3 months.

How to check if your baby’s shoes fit

Indents or red marks on your baby’s feet, or signs of teetering, dragging or discomfort when they walk, usually indicate that shoes are too tight. There should be some room — approximately half an inch — between your baby’s toes and the end of the shoe. You can check this by gently pressing your thumb at the tip of each shoe while your baby is standing.

Another way to check that your toddler’s or baby’s shoes are the right fit is by inserting your pinky finger at the back of the heel — it should fit comfortably, without too much room between the foot and the shoe.
