What to look for when Buying Kids Shoes Online?

Many parents of young children are big fans of online shoe shopping. It’s easy and convenient behind the computer or with your iPad at home. Even the most easygoing of toddlers can become whiny and weepy in the children’s shoe aisle. Unfortunately, the greatest thing about online shoe shopping is also the biggest downside when shopping for children’s shoes. You’re not in a department store so you can’t try them on until you buy them.

In the below Shoe Size Charts for Boys and girls, we’ll make it easy to understand your children’s shoe size and reduce the hassle of getting wrongly fitting shoes delivered to your doorstep.

The age group for each size may vary from brand to brand and from child to child. Our team has made an overview of the most common age group for each size based on our research. This is not a standard true-for-all size chart, but we’re convinced you find this chart useful.

How to measure your children’s feet?

Shoe sizes differ between brands and between types of footwear. That’s why we always recommend measuring both feet of your son or daughter, so you can convert children’s shoe sizes between the US, UK, and European size systems: Here’s a simple how-to post about it.

Probably you don’t feel like reading or quickly want to buy those kids’ shoes.
To make it easy, we summed up our tips to measure your children’s feet, which will take no more than 2 minutes of your time.

Measure your kid’s feet in 10 simple steps

1. Measure your kid’s feet in the afternoon.
2. Make them Stand When Measuring, but with smaller children this is not needed
3. Wear socks
4. Be precise
5. Measure both feet
6. Stand on a piece of paper
7. Start drawing
8. Measure the length of your feet
9. Find your width fitting by drawing or with measuring tape
   (for infants, toddlers and little kids shoes, this step is optional)
10. Determine your kids shoe size by age in the conversion charts

How often should my child’s foot be measured?

As a rule of thumb, consider measuring your child as follows:

• Age: 2 weeks to 6 months – measure once a month
• Age: 6 months to 12 months – once every 2 months
• Age: 12 months to 2 years old – once every 3 months
• Age: 2 years to 4 years – once every 6 months
• Age: 5 years and above – every year

Average kids Shoe Size By Age Chart in UK and US Sizes

Finding out your Children’s shoe size conversion is not as difficult as it may look.
You must understand Kids Shoe Sizing when looking out for the best children’s shoe brands, best shoes for toddlers, most durable kids shoes, or podiatrist recommended shoes for toddlers.
This exercise will save you from so much stress and extra expenses.

If you are buying a children’s shoe that uses the European sizing system the notation system is the same for babies, children, and adults.

What do you need to consider when choosing your toddler’s shoe?

• Before a child starts walking, shoes are unnecessary.
• During the winter months your child can wear soft booties to stay warm, but all foot coverings should be as non-restricting as possible.
• After your toddler has begun to walk (usually between 10 and 18 months old), you can introduce him or her to a sneaker with a flexible outsole with good traction.
• At toddler age shoes should be worn outdoors only. Inside the house barefoot is still best for toddlers.
• Check your child’s feet for blisters and other signs often, meaning their shoes no longer fit.
• Toddler’s feet tend to grow a larger shoe size every three months.
• Feel free to buy shoes slightly larger than what your child needs. 1/2 an inch clearance at the toe provides some growing room.

Basic Tips when doing Kids’ Shoe Shopping

• Start your search by knowing your children’s foot and shoe size: Measure the feet in inches or centimeters and convert them into the size you need.
• As Children’s feet grow at different rates, you should regularly measure them every few months to ensure they are always wearing a properly fitting shoe.
• Never let a child wear a shoe that is too small for their feet! Children’s feet are still growing and developing; many adult foot problems originate in poor-fitting shoes during childhood.
• Young children tend to curl their toes which can be misleading when fitting shoes. Always be sure to check that the foot is fully flat before fitting.
• Never put your child in a shoe that is more than a size too big or the child is likely to trip when walking.
• If you are buying a children’s shoe that uses the U.S. or U.K. sizing system (see chart for measurement differences in the two systems), be sure to remember that the notation system starts over at around age 6. At age five your child may wear a children’s size 13 and at age 6 your child may wear a youth size 1.
• At four years old your child’s foot will be double the size it was at birth.
• Children’s shoes can have slightly firmer soles than a toddler’s shoe, but there should still be plenty of flexibility. 
• For a kid’s feet, a little bit of arch support goes a long way. Never try to correct a child’s walking gait without a podiatrist’s informed diagnosis and recommendation.
• Between ages four and five most children’s feet grow at least a half a shoe size every four to five months.
• Avoid buying shoes that are more than one size too big or the shoe will become a tripping hazard.
• When choosing between children’s shoe uppers, breathable materials like leather and canvas are best. Children’s feet often sweat a lot.

Buying shoes for my teenagers, tips needed?

• A youth size 5.5 is equivalent to an adult women’s size 7 and an adult men’s size 6. For older children and teenagers please use our Men’s & Women’s Shoe Sizing U.S & European Shoe Sizing Guide
• Your child will usually start wearing youth shoe sizes around age 6.
• After age 6, it becomes especially important that children wear supportive athletic shoes during play, particularly if they participate in after-school sports.
• While children’s feet are more resilient and thus less prone to injury, the most common cause of chronic children’s foot pain is Sever’s disease, an inflammation of a child’s developing heel growth plate. The most common cause of children’s heel pain is participation in activities that involve a lot of running and jumping, such as soccer and basketball, without having shoes that provide enough arch support. Children’s arch support inserts are available to decrease your child’s risk of developing a painful foot injury.
