Komuello Baby First Walker Shoe Size Guide

Komuello sizing is different from regular shoe sizes.
Komuello shoes are worn on bare feet and fit snugly like a sock, so please don’t order by your child’s usual shoe size. Choose by age (great for gifts) or measure their foot and use the chart below.

How to Measure Your Child’s Feet

  1. Have your child stand on a piece of paper with their weight on both feet.
  2. Mark the back of the heel and the tip of the longest toe.
  3. Measure the distance between the marks.
  4. Measure both feet and use the longer one.
  5. 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 sizing is different from regular shoe sizes. Choose by your child’s age, or measure their foot for the best fit.

Frequently Asked Questions

My child wears a size 5 in regular shoes. What Komuello size do they need?
Komuello size numbers don’t match regular shoe sizes, so please don’t go by your child’s usual shoe size. Choose by age, which works for most little ones, or measure their foot and use the Fits foot length column for the best fit.

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, or choose by age, 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?
