Children's shoes: how to choose them

How to choose children's shoe size, shape and flexibility. Barefoot, flat feet and orthoses: what the evidence supports and when assessment is useful.

For a healthy child there is no single 'orthopaedic' shoe that makes the foot develop correctly. The most important points are simpler: the shoe should fit the child's foot, allow comfortable movement and protect it when protection is needed. Evidence on many specific design features is still limited, so rigid rules and marketing claims deserve caution.

Before walking and first steps

A baby who is not yet walking does not need shoes to shape or support the foot. Socks or soft coverings are enough for warmth when appropriate.

Once a child walks outdoors, footwear mainly protects from cold, rough surfaces and injury. On a safe indoor surface, barefoot time is reasonable if the child is comfortable.

What matters when buying a shoe

Fit

Check length and width with the child standing. There should be room for the toes without the foot sliding inside the shoe. Sizes vary between brands, so the number on the box is not enough.

Toe box

The front should follow the shape of the foot and not compress the toes. Check the longest toe, which is not always the big toe.

Flexibility

For young healthy children, a shoe should allow comfortable foot movement rather than behave like a rigid shell. Evidence does not support one universal stiffness value for every age.

Fastening and comfort

Laces or hook-and-loop closures should hold the foot without pressure points. New shoes should be comfortable from the start; pain, rubbing or blisters are not a normal 'breaking-in' phase.

A finger-width of growing room is a useful practical check, not a millimetre-perfect medical rule. Recheck fit regularly: younger children's feet can outgrow shoes quickly.

Barefoot and minimalist shoes: useful, but not magic

Walking barefoot and wearing shoes produce measurable differences in gait. This does not prove that every child needs minimalist shoes, nor that structured shoes weaken the foot. Current reviews repeatedly note that long-term evidence for many footwear features is limited.

For a healthy child, choose according to fit, comfort, activity and environment. A specific sport, deformity, neurological condition, brace or painful foot may require different footwear.

Flat feet and orthoses: two myths to avoid

A flexible flat foot is very common in childhood. Age alone does not tell us whether an orthosis is needed, and persistence beyond 8 or 10 years is not by itself an indication for treatment.

Orthoses are not prescribed to 'create an arch' in every asymptomatic child. In a symptomatic child they may be one option for improving comfort or function, but the evidence is heterogeneous and the cause of pain should first be assessed.

A rigid flat foot, marked asymmetry, persistent pain or functional limitation deserves assessment rather than simply buying a more supportive shoe or an insole.

When the shoe may not be the real problem

Repeated pain that limits walking, running or sport
Limping, clear asymmetry or a foot that is becoming rigid
Frequent blisters or pressure marks despite apparently correct sizing
Need for special footwear because of a brace, neurological condition or known deformity

If your child's foot hurts or shoe choice has become difficult because of gait, deformity or sport, the useful question is not which brand to buy, but why that child needs something different.

Sources and limits of the evidence

Footwear guidance is less standardised than many commercial messages suggest. The 2025 review found substantial variation between guidelines and noted that many recommendations still rely on expert opinion rather than high-quality trials.
