1 to 12 years · sized in millimetres

Measure the foot,
not the age.

Then leave the millimetres we tell you to leave. Every pair here states the angle its sole bends to, what its three material rows are made of, and how much room it is built to leave in front of the toes.

We describe how our shoes are made. We don't give advice about your child's feet. If you have concerns, ask a healthcare professional.

Standing · both feet · longer one wins

Three steps, one number

You need a sheet of paper, a pencil and a ruler.

Not a chart of ages. Not last year’s size. Six minutes on the kitchen floor and you will never guess again.

  1. A child's bare foot standing flat on a sheet of white paper on a wooden floor01

    Stand on paper

    Weight on the foot. A foot under load is up to 4 mm longer than a foot in the air, and the shoe has to fit the loaded one.

  2. A hand drawing a pencil line at the heel of a foot resting on paper02

    Mark heel and longest toe

    The longest toe is not always the big one. Draw both lines square to the paper, not angled to the foot.

  3. A yellow ruler measuring the distance between two pencil lines on paper03

    Measure between the lines

    Do both feet and keep the longer number. That single number is what we size from.

No ruler in the house? The printable paper gauge is free, and the card version comes in the post with any order.

Growing Room

Put the number in.

It returns a size, the millimetres it leaves, a range of months rather than a promise, and a date to measure again that we will never remind you about.

Step 1 — the measurement

mm

Measure with the child standing, weight on the foot. Measure both feet and use the longer one.

What are you buying?

Each line leaves a different allowance, so the recommended number changes with it.

Step 2 — what we would send

Recommended size

EU 25

Room in front

12 mm

Everyday Kids shoes are built with 12 mm of allowance. 12 mm covers a normal stride plus a few months of change, without leaving enough room for the foot to slide.

Likely wear time

An estimate, not a promise. Children grow at very different rates.

Written here for you to note down. We will not email or notify you about it.

We don’t recommend more than one size above the measured fit. Too much room makes the foot slide forward and the toes grip.

The same foot across the range

A 155 mm foot is not one number. Rain boots are sized over a thick sock and sandals are worn without one, so the recommendation moves.

These two numbers stay in your browser while you use this page. If you send them to us with an order we keep them for at most 12 months, use them only to pick a size, and delete them if you ask. We never use them to build a profile or to target advertising, and we never send you a reminder based on them.

Two things we will not tell you

Bigger is not longer. It is just looser.

Most children’s shoe shops are quietly pleased when you buy a size up: the pair lasts longer, you come back later, everybody is happy. We think that trade is worse than it looks, so here is the argument against our own next sale.

We don’t recommend more than one size above the measured fit.

Too much room makes the foot slide forward at every step. The heel lifts out of the back of the shoe, the toes grip to hold the shoe on, and the pair that was supposed to last longer gets worn differently instead.

We don’t suggest buying next year’s size now.

Feet don’t grow evenly, and the shape changes as well as the length. A pair bought a year ahead is a guess about a foot that does not exist yet, and that is why there is no back-to-school countdown anywhere on this site.

On every single product page

Four blocks that are not optional.

If any one of them is missing from a pair, our own code refuses to list it. That is a build-time rule, not a promise in a policy document.

Three material rows

Upper, lining and insole, outsole. Each one named as leather, coated leather, textile or other materials, with the actual material written next to it. This is a legal label, not a marketing panel.

Five chemical checks

Chromium VI, azo dyes, nickel release, phthalates, free formaldehyde. Each states the limit, the test method, and whether it applies to that pair or not.

The angle the sole bends to

Measured by hand, the same way every time, and the method is written next to the number so you can repeat it on the pair in your hallway.

Where the line is

We describe structure, materials and numbers. We do not tell you what any of it will do for a child’s feet, because that is not a claim a shoemaker is in a position to make. We also do not sell orthopaedic or corrective footwear of any kind.

Safety, materials and the tests behind them

Under three years old

No laces. Nothing that can come off.

Everything in the First Walkers line closes with hook-and-loop or elastic, and carries no decorative button, bead, pom-pom or badge of any kind. Where a pair further up the range does carry a decorative part, it has passed a 90 N pull test held for ten seconds and it says on the page that it is not for children under three.

Nothing in this catalogue carries a cartoon, a character, a film tie-in or anybody else’s trademark. Plain shoes, every one of them.

Priced in one currency

Every price on this site is in US Dollars (USD). There is no currency switch, because there is nothing to switch to.

Terms of sale

Free standard shipping over $89

Standard shipping is $12 below that. Dispatch in 1–2 business days, and never more than 30 days to deliver.

Shipping & returns

14 days to change your mind

Try them indoors on carpet. Outdoor wear on the sole is the one thing that stops a return, and we say so before you buy rather than after.

Right of withdrawal

Three-year legal guarantee

Portuguese law gives you three years on a defect. A foot that has grown is not a defect; a sole that has come away is.

Legal guarantee

Nurseries and schools

Buying for thirty feet instead of two?

Tell us the age bands and, if you have them, the foot lengths. We will come back with a size distribution rather than a catalogue, and we can supply entirely plain pairs with no pattern at all.
