How Do Baby Shoe Sizes Work?

Baby shoes sizes are not just smaller versions of adult’s sizes. It’s a totally different category of shoe sizes specifically tailored for the foot measurement of newborns, infants, and, toddlers using foot length in inches. Unlike adult sizes, baby shoe sizes are the same for both girls and boys. Baby shoe sizes are subcategorized into those for newborns (0-2 months), infants (2-12 months), and toddlers (1-3 years).

Newborn Shoe Size Chart

While they may not need shoes at this point, newborns still need to wear socks or booties to protect their feet from the cold. Baby socks are usually made from hypoallergenic, lightweight, and breathable materials such as cotton or wool.

At a Glance

  • Add 0.5 – 0.7 inches for the shoes to give your child’s feet enough wiggle room and not restrict the proper growth of their feet. A poor fit could lead to more serious problems later on.
  • After measuring both feet, when it is time to shop for the shoes, make sure to use the longer foot measurement as the basis for the size. Better have an allowance rather than buy a pair that only fits one foot.
  • As babies’ feet grow rapidly, make sure to measure their size often. It is recommended that foot measurement is taken every 2-3 months in the first 24 mos of age to ensure correct shoe size.
  • If buying shoes that you plan your child to wear with socks, measure their foot size while wearing them to anticipate the additional length and width needed for proper fit.
  • Before buying shoes online, identify the sizing standard used whether it is in US, UK, or European size to make sure that the size conversion is correct.
  • US shoe size is different from European shoe sizes. Euro size is also different from UK shoe sizing. To convert baby shoes for newborns from the US to the UK, just remember that UK shoes are usually just one-half size lower than US sizes. See all international Sizes

What are the best shoes for babies?

Newborns don’t need shoes at this point since they are mainly snuggled in bed and are too small to carry the weight of the shoes. Socks are instead more appropriate to keep their feet warm and cozy. Socks made of cotton, wool, or a combination of both with enough elasticity is recommended.

Socks or shoes?

There is no clear rule to follow on whether parents should opt for their little ones to wear socks or shoes although in general socks are better to keep babies’ feet warm and cozy, while shoes are for outdoors. Recommended materials for socks for babies include soft cotton with some elasticity to keep it on the baby’s feet.

For babies who will start learning to walk by this age, a soft-soled shoe made of lightweight, breathable materials is necessary to protect the child’s feet from rough surfaces and splinters when outdoors.

Non Slip Socks

Non-slip socks keep your child from slipping since it has rubber grips on the sole for better hold on smooth surfaces.

Do babies wear socks with shoes?

In general, wearing socks with shoes is recommended for everyone, and that includes the little ones. Wearing socks help reduce friction between the feet and the shoes, absorbs moisture and damage to the skin from constant rubbing with shoes. However, socks should be properly fitted as very tight socks could also have harmful effects such as hampering the growth of the feet especially for babies, and restricting air and blood circulation.

Should babies wear shoes when crawling?

When your baby is just a newborn or in the infant stage, wearing shoes is still unnecessary. When they’re crawling, soft socks or at most, non-skid socks with soles will work just fine. This will allow them to move more freely and not worry about supporting the weight of the shoes. Also, no matter how you put it, shoes (and even socks) will still fall off their tiny feet.

How long should babies wear soft-soled shoes?

Soft-soled shoes in general can be useful until the baby is 24 mos old. Beyond this, babies learn to be confident walking and tend to be more adventurous into walking on different surfaces which may require shoes with firmer soles and sturdier materials.

Do babies have bones in their feet?

Baby’s feet do not contain any bone but a mass of cartilage. Over time, this will develop into the 28 bones seen in the adult foot. Full development happens when the child grows to their late teens.

Ingrown toenail in babies – causes and treatment

Did you know that over 65% of kids are wearing shoes that are too small for their feet? An ingrown toenail in a baby is a nail (usually affecting the biggest toenail) that’s putting pressure on the skin as it grows or presses into that area. It is painful for babies, and shoes early signs such as redness in that skin or swelling.

This condition is commonly caused by nails that grow too long that it tends to curve and pinch on the skin. Wearing very tight shoes or socks could also cause ingrown.
To treat this, soak your baby’s foot or the affected toe in warm, soapy water two times a day and apply an antibiotic cream as recommended. When the affected toe is less swollen, try to etch the toenail out of the cuticle little by little so as not to hurt your baby. To prevent any future occurrence, cut the nails as often as needed to prevent them from growing too long.
