 Wearing the wrong size or type of shoe in the short term causes blisters, rubbing, bruising and calluses, but in the long term it could affect foot development and result in musculoskeletal issues in the future.” 

 Baby feet

Adequate length and width: All children’s footwear should be measured for length and width, and fitted by an appropriately trained shoe fitter.

Broad base of heel: This should be as wide as the heel to give stability, and be made of a shock-absorbing material.

Height of heel: You are looking for a slight heel to provide sufficient shock absorption, ideally around a quarter of an inch. Completely flat shoes such as ballet pumps provide little shock absorption but heels of 2cm of higher can shorten calf muscles.

Toe area shape: This should be foot shaped and not pointed, or excessively tapered.

Holding the foot in the shoe: It is important that the shoe is kept on the foot by laces, Velcro or ‘T’ bar, which acts like a seatbelt in a car, holding the shoe onto the foot. This helps to prevent toe deformities, as lack of support to keep the shoe on the foot can allow the foot to slide up and down in the shoe and damage the toes or cause the toes to claw to help keep the shoe on.

Material: Leather is the best material for kids’ shoes as it is flexible and soft, but hard-wearing. It also lets air in but keeps moisture out, meaning feet stay cool and dry in most conditions. Avoid shoes which are largely made of other materials (synthetics and plastics).

Adequate depth of toe area: This is particularly important in individuals with a big toe that curls up at the end and helps to avoid toenail problems.

Support: The shoe should offer sufficient support for the foot. The shoe should not bend or crumple excessively. Plimsolls and ballet-pump shoes are examples that bend too easily.

If you are concerned about your child’s walking or feet, see your GP or health visitor for advice.

It is very important to establish the correct shoe size for your infant's feet.
Shoes should not be too big or too small, and they must be easy to fit and remove.
Shoes that don’t fit properly can stifle natural growth, and can cause discomfort and permanent damage to the foot.

Because baby shoe sizes can vary between footwear brands and manufacturers, it's important to have your child's feet measured by a shoe professional. Once you have the length in inches, you can seek out a comfortable fit.

But you can use this quick measure process if you wish:

Feet tend to expand during the day, so it is better to measure feet later in the day.
Be prepared for a bit of a struggle and some resistance from the infant.

What you will need:

Foot measurements

Size guide area

Two adults.
A box for the child's foot to be measured against
A sheet of paper
A pen or pencil
A ruler
Tape to fix the paper and the box to the table.

Foot measurements

Firmly tape the sheet of paper to the table.
Draw a line near one end of the paper.
Place the box with one edge exactly on the line.
Tape the box in position on the paper.
It is best for the child to be standing so that their full weight is exerted on the foot.
Gently move the back of the child's heel up against the box as shown in the diagram above.

 Size guide toes curled




Make sure that the heel is only just touching the box. (A)
Gently press down on top of the foot (B) to ensure that it is flat on the paper. Toes must not be curled. (D)
Draw a line exactly in front of the longest toe, taking care to ensure that the pen is as upright as possible. (C)
Repeat the procedure for the other foot.
Lift the infant and the box off the paper.
Measure the length between the two lines on your sheet of paper to establish the length of the longest foot.
One foot may be longer than the other, so make sure you use the measurement of the longest foot.
Consider the shape of the child's feet. If the foot is very chubby, you may want to consider one size bigger.
Consult the size chart for the nearest approximate inside shoe length of the shoe.
When in doubt, it is usually safer to choose one size bigger.

As a general guide, use the following chart of baby shoe sizes, which shows foot length matched to each approximate age. This chart works for most shoe styles your baby will wear at these ages, including sneakers, sporty sandals and boots.

Or you can print this sheet below for quick guide:

The shorter measurement in each size above allows for up to 10mm extra room.

Note that the overall size of the shoe may vary slightly depending on the style.

If in doubt always go for bigger size
