How to measure your child’s foot

Stand your child on paper with the heel against a wall.
Mark the tip of the longest toe and measure with a ruler.
Measure both feet, use the longer one, ideally late in the day.
Add 0.5–1 cm for comfort and growth.

Which shoe for which stage?

Before walking: soft shoes or thick socks for warmth; bare feet are best.
First steps: a soft, flexible, non-slip sole with a wide toe, like our soft-sole non-slip toddler shoes (11–13 cm).
Confident walkers: a slightly firmer sole that still bends at the front.

How often do kids’ feet grow?

Every 2–3 months in the first year, every 3–4 months from 1 to 3 years, then every 4–6 months. Re-measure regularly, especially if the foot looks red after shoes come off.
