Komuello sizes are different from regular shoe sizes.
Komuello shoes are worn on bare feet and fit snugly like a sock, so they’re sized smaller than regular shoes. Don’t order by your child’s usual shoe size. Measure their foot and use the chart below. If you can’t measure, choose one size up from their usual size.
Komuello Size Chart
| Size | 👣 Fits foot length | Shoe inner length | Age guide |
|---|---|---|---|
| 5 | up to 111 mm (4.4 in) | 115 mm (4.5 in) | 6–12 months |
| 6 | 112–121 mm (4.4–4.8 in) | 125 mm (4.9 in) | 12–18 months |
| 7 | 122–131 mm (4.8–5.2 in) | 135 mm (5.3 in) | 18–24 months |
| 8 | 132–141 mm (5.2–5.6 in) | 145 mm (5.7 in) | 24–36 months |
👣 Sizing tip: Use the Fits foot length column. It already includes 3–4 mm (1/8–1/4 in) of wiggle room. Ages are a general guide only.
How to Measure Your Child’s Feet
- Have your child stand on a piece of paper with their weight on both feet.
- Mark the back of the heel and the tip of the longest toe.
- Measure the distance between the marks.
- Measure both feet and use the longer one.
- Find that number in the Fits foot length column.

How Komuello Sizing Works
Komuello Baby First Walker Shoes combine the comfort of a sock with the protection of a shoe. Because they’re worn on bare feet with no sock inside, they’re designed to fit snugly, hugging the foot like a sock, so they stay on securely as little ones crawl, walk, and play. That’s why Komuello sizes run smaller than regular shoe sizes, and why measuring your child’s foot is the best way to find the right fit.
Frequently Asked Questions
My child wears a size 5 in regular shoes. What Komuello size do they need?
“For sizes 5 and 6, many parents find one size up fits best. Komuello is worn barefoot with a snug, sock-like fit. Measuring your child’s foot is always the most reliable way to choose.”
Do Komuello shoes feel tight?
They’re meant to feel snug, like a well-fitting sock, which keeps them securely on little feet. There should still be a little space past the longest toe, and your child should be able to move their toes comfortably.
My child is between sizes. Which should I choose?
Choose the larger size. It leaves room for growth and natural movement.
How do I check the fit?
With the shoes on and your child standing, there should be a little space past the longest toe, and the heel should stay in place when they walk.
Can Komuello shoes be worn with or without socks?
Yes. They’re designed for bare feet, which is how most families wear them. Tights or thin socks work too.
Why does Komuello sizing differ from other shoe brands?
Komuello’s flexible, sock-like construction fits differently from structured shoes. Measure your child’s foot rather than comparing sizes across brands.
Are Komuello shoes good for first walkers?
Yes. They’re lightweight and flexible, designed to support natural foot movement, and the non-slip sole gives babies traction as they build confidence in their first steps.
What if the size isn’t right?
No problem. Every order comes with free returns. (Link your returns page here.)

1. Keeps Little Feet Cool & Dry
Tiny air holes and an air-pocket layer between the sock and the sole promote airflow to help reduce heat and moisture buildup.
2. Supports Natural Foot Development
The thin, flexible sole bends with every step, allowing natural movement while giving early walkers gentle support.
3. Safer, Glue-Free Construction
Our patented double injection molding bonds the TPE rubber sole directly to the cotton sock layer, creating a durable, seamless bond without glue.
Breathable Holes
Unlike many sock shoes, Komuello has real air holes that go all the way through the sole. They let air flow to keep little feet cool and dry, and let water drain out during water play.
Inner Sole Comfort
A soft, seamless sock layer with no loose threads, stiff seams, or glue inside, for all-day comfort against bare skin.
Machine washable in a laundry bag on a gentle cycle, in cold or lukewarm water (max 30°C / 86°F). Hand washing keeps them new longer. Lay flat to dry. Wipe the rubber sole clean with a damp cloth or wet wipe. Do not tumble dry, bleach, iron, or dry clean.
