Find the right shoe size for your kidsā feet
July 3, 2022
Healthy feet are the foundation of growing children, quite literally. Thereās no stage in life when finding the right size shoes matters more.
Thatās why weāve put a short guide together to help you measure your childrenās feet properly.
What youāll need
The best piece of kit for the job is a foot gauge if one isnāt available, you can use the following equipment instead.
If a foot gauge or piece of paper isnāt available:
- Inner sole or sockliner
- Ruler
If a foot gauge or inner sole/sockliner isnāt available:
- Piece of paper
- Pen or pencil
- Ruler
What happens if children wear shoes that donāt fit?
Younger childrenās feet are mostly cartilage ā delicate tissue that turns into bone as your child grows into adulthood. Because bones arenāt fully formed, itās easier for ill-fitting shoes to deform young feet. This typically presents itself in one of three ways:
- Bunions ā bony lumps near the big toe that force it to point inwards
- Bunionetttes ā like a bunion but on the smallest toe
- Hammer toes ā when toes become permanently bent at the first or second joint

Even though kidsā shoes like our new NOVABLAST 2 and PATRIOT 13 are designed with a natural growth margin, allowing space for growing feet, itās important to follow some simple steps to make sure you find the right shoe size for your child.
Read on to find out how to measure your kidsā feet correctly.
Before you start
The easiest way to measure childrenās feet is with a foot gauge, but if you donāt manage to pick one up online an inner sole/sockliner or piece of blank paper can also do the trick.
Try and check your childās shoe size in the evening as feet usually swell during the day, and youāll need somewhere to take a note of the measurement.
Make your children feel involved throughout the measuring process by talking through each stage ā they may even enjoy it. If not, think about ways to keep their mind occupied without moving around.
Step 1: Stand up straight
Start by asking your child to stand up straight on a flat surface.
Place their feet shoulder-width apart and make sure theyāre distributing their weight evenly while facing forward.
Pick up the foot gauge to start measuring. If you donāt have a foot gauge you can measure your childās feet with a piece of paper and a pen.
Step 2: Measure the foot
Open the gauge as wide as possible and place one end against your childās heel.
Slide the gauge down until it gently touches the longest point of your childās foot.

Repeat for both feet.
Using an inner sole/sockliner
Start with your child sitting down so their feet can touch the floor.
Line up your childās heel with the heel of the inner sole/sock liner and ask them to stand up.

Mark the inner sole/sock liner with a pen at the longest part of the foot.
Repeat for both feet.
Using a piece of paper
Ask your child to stand on a blank piece of paper with their heels lightly touching against a wall.
Mark the paper with a pen or pencil at the heel and the longest point of your childās foot.
Repeat for both feet.
Select the right size
Take the longest measurement from your foot gauge and add one euro size to give a growth margin.
If youāre measuring feet with socks on, take 1-3mm off from the measurement.
If youāre using a piece of paper or inner sole/sockliner, take the longest measurement and add 5-10mm. Again, if youāre measuring feet with socks on, take 1-3mm off from the measurement.
