Before purchase:

It is important that you check your child's foot size, both length and width. Follow our guide below.

How to measure your child's foot

For first-time buyers. You'll need A4 paper, tape, a pen and a ruler, and a flat, hard floor next to a wall.

1Tape down, heel to wall, mark the longest toe

Mark the longest toe. Tape the paper down.

Tape an A4 paper flat on the floor, with one edge against the wall. Stand your child on it with the heel touching the wall, then mark the tip of the longest toe.

The longest toe may not be the big toe. Check which toe reaches furthest.

2Mark the widest part, on both sides

Pen marking the widest point on the right side of the child's foot, level with the ball of the foot
Right side of the foot.

Mark each side of the foot at its widest point, usually around the ball of the foot.

3Measure with a ruler

Ruler measuring foot length from the wall edge of the paper to the toe mark, 15.5 cm
Length: wall edge to toe mark (15.5 cm in this example).
Ruler measuring foot width between the two side marks, 6.5 cm
Width: between the two side marks (6.5 cm in this example).

Length: from the wall edge of the paper to the toe mark. Width: between the two side marks.

4Match it to the size guide

Choose a size where the Max Feet Length and Max Feet Width are at least your child's measurements. Example: a foot measuring 15.5 cm long and 6.5 cm wide.

Size Max length Max width Fit
8.5 / EU26 15.5 cm 6.7 cm Just right barefoot or in sandals. Too tight with socks or covered shoes.
9 / EU27 16.2 cm 6.8 cm Best fit. Fits well, with room to grow. Work with thin socks
10 / EU28 16.9 cm 6.9 cm Fits loose. Add thick socks and choose a "Snug" design.

Good to know

  • Measure both feet and use the larger one.
  • Always measure while standing for most accurate readings.
  • Wearing socks? Measure with socks on.
  • Feet swell during the day, so measure in the afternoon.

*Alternative method - Wet foot print measurement (For little feet that can't stay still)

Place a paper outside your bathroom during shower time. As your child exits the bath, have him/her stand firmly with both feet on the paper. Measure the wet footprints.

*Alternative method:

Printable Size Measurement (or Printable Insole Measurement - for Baby Size only) for a quick check of our sizing. Remember to scale at 100% to get the most accurate size suggestion.

Because little feet grow quickly, it is a good idea to check every month to make sure the shoes still fit.

After purchase:

We suggest that you let your child try on the shoes right away!

When standing, there should be just enough room to squeeze your pinky between your child's heel and the back of the shoe, and roughly a thumb-width between the tip of your child's longest toe and the front of the shoe.

If the little toe is pressed against the side of the shoes (visible bumps from outside), that means the shoe's width is too small for your child's feet. 

Checking fit with removable insole

Many of our shoes have removable insoles, so another way to check the fit is to remove the insole and have your child step on it while standing.

For a perfect fit, your child's heel should fits right inside the heel cup, and there is at least 1cm between the longest toe and the tip of the insole. This is also a good way to check for width fit. Your child's foot should not go over the side edges of the insole while standing.
View the insole fit-check guide

Depending on the design and your child's instep, some shoes may be a little tight even when the length and width fit. In this case, talk to us to get a design change (if eligible for exchanges).
