The growing-feet challenge
Sizing kids' shoes online has always been a bit of a gamble.
Children's feet grow quickly, and sizes can vary between brands and styles. SizeWise measures length and width, then connects those measurements to the footwear being considered so families can shop with greater confidence.
How it works
Four simple steps to a better fit.
01
Grab your phone and paper
Stand up straight and place one bare foot in the middle of a flat A4 sheet of printer paper.
02
Open SizeWise and add a profile
Click the button to open SizeWise and follow the friendly instructions to create or select a profile for your child.
03
Measure with your camera
SizeWise measures length, width and shape, then calibrates the recommendation against the footwear style you are shopping.
04
Shop with confidence
Use the personalised size recommendation when choosing the available size for the footwear you want to buy.
Why it works
Built around real feet, not a generic chart.
Generic size charts miss what makes each footwear style different. SizeWise considers more than foot length and can connect each profile to calibrated sizing information for the footwear being considered.
Fewer returns, happier feet
A better size recommendation means less uncertainty, less shipping back and forth and shoes that are more likely to fit.
Footwear-calibrated, not generic
SizeWise connects each foot profile to calibrated sizing information for the specific footwear being considered.
No app, no fuss
The measuring experience runs directly in a compatible phone browser. Measure, size and shop.
Accurate measurement
SizeWise measures the foot with millimetre-level precision to support a more informed size recommendation.
Recommendations are available across the footwear range that has been calibrated for SizeWise.

Good questions
The short answers.
Why is children's shoe sizing so confusing?
Children's shoe sizes vary by brand, style, and foot shape, making a universal size impossible.
Does SizeWise cost anything to use?
No, SizeWise is completely free to use.
Why do I need an A4 sheet of paper?
The A4 sheet of paper is essential to capture accurate foot measurements as it is the reference object that is used to accurately calculate the dimensions of the foot.
Is my child's data private and secure?
Yes, your measurements are used only to provide a size recommendation and are handled securely.
Is the shoe size different if my child wears socks?
Generally, no - your child's shoe size does not change just because they're wearing socks. However, the thickness of the socks can affect how the shoes fit so be sure to measure without socks to ensure the most precise recommendation with SizeWise.
Do I need to download an app?
No. It opens directly in your phone's web browser.
How often should I measure my child's feet?
Try to measure every 2 months or before buying new shoes, as young children's feet grow quickly.
