Sizing & fitting guide
The right fit makes all the difference.
Kids' feet grow fast — and every foot is different. Use this guide to measure at home, find the right size, and fit your Omongo shoes correctly from day one.
Step 1 — measure
How to measure at home
All you need is a piece of paper, a pen, and a ruler. Measure in millimetres for accuracy, and always use the larger foot.
Place paper on floor
Lay a blank A4 sheet flat against a wall.
Stand heel to wall
Heel touching the wall, foot flat on paper.
Trace around foot
Trace both feet. Always use the longer measurement.
Measure heel to toe
Measure in millimetres to the longest toe.
Match to the chart
Use the size chart below to find your EU size.
Check the fit
A thumb's width at the toe means room to grow.
Always measure in the afternoon — feet swell slightly through the day. If between two sizes, always size up. Our shoes include approximately 10mm of built-in growth room.
Step 2 — find your size

Step 3 — your stage
Omongo stages for 4–8 year olds
Both stages cover the 4–8 year range. Choose based on your child's activity level and foot development.
Growing
UK 9.5 – 11.5 · US 10 – 12
Active, confident walkers who are running, jumping, and exploring. Flexible soles and wide toe boxes support natural foot development at its fastest phase.
Kid+
UK 12 – 1 · US 13 – 1.5
School-age children with more structured needs. Durable materials and supportive structure that keep up with their growing independence.
Step 4 — fit for comfort
How to fit your Omongo shoe
Follow these 5 steps every time to ensure a safe, comfortable fit.
Open all fastenings
Loosen velcro fully and pull tongue toward the toe.
Slide foot in
Guide heel-first, keeping toes clear of the opening.
Heel to the back
Stand child upright, heel firmly at back of shoe.
Fasten securely
Snug but not tight — foot should flex freely at ankle.
Check toe room
A thumb's width of space = the right fit.
