A baby's first shoe arrives later than almost anyone expects, and that is the fact that shapes the whole decision.
A first shoe makes sense once your baby is already walking on their own outdoors, not before. This usually happens somewhere between 10 and 18 months, but age is only a guide: the real sign is that they take steps independently outside. Until then, barefoot at home and a sock for the cold is what supports the foot best. When that shoe does arrive, its job is to protect from the ground and the temperature, nothing more.
That gives you the criteria: a thin, flexible sole, the same height at heel and toe, a wide toe box so the toes can spread, a heel without a heel counter, and a flat, removable insole so you can check the size at home. With 0.8–1.2 cm of room in front of the longest toe.

The stages of the foot before the first shoe
Before walking on their own, a baby's foot does not need a shoe at any point. It needs to move, touch the ground and grip it. Shoes with a sole come into play when independent walking outdoors begins, and until then all that is needed is warmth that does not squeeze. What changes from one stage to the next is not the shoe: it is how much it gets in the way.
| Stage | Approximate age | What the foot needs |
|---|---|---|
| Before moving around | 0–6 months | Nothing. Barefoot, or a thin sock for the cold |
| Moving around on the floor | 6–10 months | Non-slip sock or bootee, no sole |
| Independent walking | 10–18 months | First shoe with a sole, outdoors only |
The ages really are approximate, not a scale to be met. Some babies walk at 10 months and some at 16, and both are perfectly normal.
The first months: the foot works best with nothing on
A newborn's foot has 22 bones, flexible and still cartilaginous. By around age 3 there will be 45, still not fully joined or ossified, and the final structure is not complete until around age 18, with most of the development concentrated in the first 8 years. At this stage there is no weight-bearing and no contact with outdoor surfaces, so the only goal is warmth. A thin sock, without thick seams or a tight elastic at the ankle, does that job entirely.
There is a sensory reason too. During the first years, the receptors on the sole of the foot outnumber those in the hand. At this point the foot is one of the main organs a baby uses to read the world, and covering it with a sole switches off part of that information.
When they start moving around: grip, not protection
When crawling or pushing themselves along the floor, little ones use their toes as a lever. A narrow or stiff shoe prevents this, and that is where it can hold back the development of the big toe. A non-slip sock or bootee solves the only real problem at this stage, which is slipping on smooth floors, without adding stiffness.
It is worth saying even if it feels uncomfortable: crawling is not a compulsory milestone. Child development specialists stopped considering it essential some time ago, and they do not see its absence as a sign of anything. Many little ones walk without ever having crawled.
And the most common mistake at this stage: putting shoes on so the baby learns to walk. A shoe does not teach a child to walk or bring that moment forward. What it does is change the information reaching the foot while the baby works it out on their own.
Independent walking: the shoe comes in, and only outdoors
When your baby takes steps on their own outside, a problem appears that did not exist before: the ground. Stones, temperature, damp, surfaces that cut. That is where the shoe has a clear function, and that is it. Indoors, staying barefoot remains the best option for a long time.
What makes a shoe respect the foot during the first steps
A barefoot shoe for first steps does five things at once: a thin, flexible sole, the same height at heel and toe, a wide toe box where the toes can spread without touching the sides, no heel counter, and a flat, removable insole. All five can be checked by hand in the shop or when you open the box. Four out of five is not enough.
The difference from conventional baby shoes is not one of style, it is one of structure. Conventional shoes usually have a rigid heel counter, a thick sole with a raised heel and a narrow toe box. Each of those three features is sold as a help, and none of them is: whatever the foot receives from outside, it stops building from within.
1. A thin, flexible sole
Hold the shoe by the toe and the heel with one hand and try to bend and twist it. If it gives without resistance, it works. If you need both hands, it is too stiff for this stage. The thickness should stay under one centimetre.
There are two reasons. A thin sole lets information from the ground through, which is what the foot uses to adjust its balance step by step. And a flexible sole lets the foot bend where it naturally bends, not where the shoe allows it to. Thick, cushioned soles feel comfortable when you touch them, but what they actually do is switch off that information.
2. Heel and toe at the same height
Lay the shoe on its side on a table and look at the profile. The heel and the toe should sit at the same level. This is called zero drop, and it simply means the shoe does not tip the foot forward.
In a foot that spreads its load roughly 70% on the heel and 30% on the forefoot, a one-centimetre rise can bring that split closer to 50-50. In structures that are still forming, that changes how the bones and joints are loaded from the very first step.
3. A wide toe box
Take out the insole and place your baby's foot on top. The toes should stay inside the outline without touching the sides, with room to fan out. If they spill over the edges, the last is too narrow for that foot.
More than half of little ones have a big toe that is longer than the others, so width is not an aesthetic extra: it is what allows the foot's own muscles to work while walking.
4. No heel counter
A baby's heel does not need any piece holding it from the outside. The shoe stays on thanks to the last and the fastening, not a rear reinforcement. Pinch the heel of the shoe between two fingers: it should give without resistance. If you feel a hard structure, that shoe is doing a job the foot needs to do by itself, and the ankle does not get stronger because nothing is asked of it.
The argument that a very active little one needs a stiffer shoe "so it lasts" does not hold up: the shoe will last as long as the foot stays in that size, which at this age is a few months.
5. A flat, removable insole
Flat means no arch support and no raised areas. The standard arches in insoles are not made for anyone's foot in particular, and there is evidence that they do not help form the arch, which develops by standing up and walking.
Being able to take it out matters for a very practical reason: it is easy to wash and can be aired, keeping the inside of the shoe dry at all times.
About the "barefoot" label
The word is not regulated. Anyone can use it, and it appears on shoes with a rigid heel counter, a raised heel or a pointed toe. There is no shortcut: the five checks above are the only guarantee, and you can do them with the shoe in your hand in under a minute.
How to measure the foot at home and get the size right
Ideally, measure with the printed template from our SIZE GUIDE. It is really easy to do at home while looking at your little one's foot.
To do this you can print the template or draw it on a sheet of paper, always making sure it is to scale by checking the measurements.
At Feroz we recommend leaving between 0.8 and 1.2 cm of room between the longest toe and the end of the insole, and moving up a size when only 0.4 cm is left. That margin leaves space for the foot to expand when walking without the shoe slipping around. The most reliable way to check is to measure the foot: print the template and place the foot on top.
The template method, step by step
- Print the shoe template and place it on the floor, on a flat surface. Make sure the scale is correct by checking the measurements on the document or against the size of a credit card.
- Stand your baby on top, with the heel lined up with the back edge. Standing, not sitting: the foot lengthens when it bears weight.
- Look from above. There should be between 0.8 and 1.2 cm in front of the longest toe, which is not always the big toe.
- Look from the sides. The toes should not stick out of the outline anywhere.
- Repeat with the other foot. It is normal for one to be slightly bigger: go by the bigger one.
Why buying a size up costs you
One size too big is as harmful as one size too small. A small shoe bothers and compresses. A big shoe does something less visible but just as real: the foot slides inside with every step and the little one ends up gripping the shoe with their toes to hold it on. That tenses the muscles and alters their gait from day one. A bigger size does not last longer, it just works worse.
How often to check
From 0 to 15 months, the foot grows half a size every two months, roughly 3 mm. From the first steps onwards, that slows to half a size every 3 or 4 months. In practice, this means doing the template check every few weeks in the first year and every two months after that. There is no need to write it down: you will notice it on the template before you notice it in your little one's mood.
If you have questions about how your baby's foot is developing, notice asymmetries when they walk or something worries you, ask a paediatric podiatrist. Barefoot shoes support the natural development of the foot, but they are no substitute for professional follow-up.
Which Feroz model suits each case
All the models in the baby line share the same base: a thin, flexible sole, zero drop, a wide last with a rounded toe and a flat, removable insole. What changes between them is the fastening, the opening at the instep, the material and how much protection they give against the weather. In other words: none of them respects the foot more than another, and the choice depends on foot type and use.
If you don't know where to start, start with Paterna. It is the most versatile model in the line and the only one with Plus sizes, so it also works as a reference to find out whether your little one needs more width.
| If your case is... | Model | Why this one |
|---|---|---|
| Standard foot, everyday use | Paterna | Double hook-and-loop fastening that adjusts the fit without narrowing the last. The only model with Plus sizes (S+, M+, L+, XL+) for wide feet or a high instep |
| Standard foot, a more neutral design | Faura | Same structural base, a more urban look |
| An instep that is hard to get shoes on | Moraira | Wide opening at the instep, the foot goes in without forcing |
| You want suede or more premium materials | Cheste | Recycled suede and microfibre, same last |
| Heavy use, a little one who already runs and climbs | Biar | More breathability for continuous use |
| Rain and mud, now and then | Bernia | Wellington boot with a soft shaft. See the note below |
About Bernia and boots in general. At this age, boots and ankle boots are not the default option: the ankle bones are still getting stronger through walking and need freedom to move. The exception is a shaft that keeps warm or protects without limiting ankle movement, and Bernia is built on that principle. For rainy, muddy days, yes. As an everyday winter shoe, one from the table above is a better choice.
You can see the full season with colours and materials in baby shoes. If you are still unsure which last suits your little one's foot, the model guide sorts them by foot type and use.
Sizes in the baby line
The baby line does not use European sizing: it goes by S, M, L and XL, with Plus (+) versions that give more width while keeping the same length. Before buying, convert the foot's centimetres into a size using the size guide. And don't use the size they wear in another brand as a reference: between brands the difference can be more than one size.
Quick summary
| If your situation is... | The answer is |
|---|---|
| Your baby is not yet walking on their own outdoors | Barefoot indoors, non-slip sock. No sole |
| Already walking on their own outside | First shoe: thin, flexible sole, zero drop, wide toe box |
| You don't know which model to choose | Paterna. If the instep is tricky, Moraira |
| Unsure about the size | Insole out, foot standing on it, 0.8–1.2 cm in front |
| A shoe advertised as barefoot | Bends with one hand, level profile, heel that gives when pinched |
| Cold and rain | Bernia for wet days. For everyday, better a shoe |
Frecuently Asked Questions
When should I put the first shoes on my baby?
When they walk on their own outdoors, which usually happens between 10 and 18 months. Before that, shoes serve no purpose: indoors, it is best to be barefoot, and for the cold, a thin sock is enough. The sign is not age, but autonomous steps outside the home.
What is the difference between minimalist (respectful) footwear and conventional baby footwear?
Minimalist footwear protects without restricting. It has a thin, flexible sole, the heel and toe are at the same height, a wide toe box, a flat insole, and no rigid heel counter. Conventional footwear adds a rigid heel counter, elevates the heel, and narrows the toe box. During the first steps, that difference changes how the foot lands.
How do I know if my baby’s shoes fit well?
Remove the insole, place it on the floor, and have the baby stand on top of it. There should be between 0.8 and 1.2 cm in front of the longest toe, and the toes should not overhang the sides. Check both feet: the larger one determines the size. When there is 0.4 cm left, it is time to change them.
How often should I change footwear during the first steps?
From 0 to 15 months, the foot grows half a size approximately every two months. After the first steps, it slows down to half a size every three to four months. The practical approach is to check the insole every few weeks at first and every two months later, without waiting for the little one to complain.
What happens if my baby wears shoes before walking?
There is no benefit and, in fact, interference. Before autonomous walking, the foot uses the toes to grip and push, and the sole collects information from the ground that the baby needs for balance. A sole covers both things. A non-slip sock resolves the only real risk, which is slipping.
How do I measure my baby’s foot at home?
The most reliable method is to use the removable insole from the shoe itself with the baby standing on it. If you don't have the shoe yet, Feroz’s size guide has a printable insole: place the foot with the heel against the wall, mark the longest point, and check that there is 0.8–1.2 cm in front.
