How Do Boys Shoes Sizes Work?

This depends on the age of your boy. When they are a toddler, your boy will wear “small kids shoes” which run from size 0-13. Most boys will wear toddler shoes until they are up to 4 or 5 years old. Most 4 year old boys, for example, will wear a size 11 toddler shoe. Toddler sizes are often marked with a “T” – so a size “11T” would be a size 11 toddler shoe.

Next, there are “Youth” shoe sizes. These range from 1-7 and are often labeled with a “Y,” so a size 1Y would be a size 1 youth shoe. Youth sizes are for bigger boys – a size 1Y shoe is bigger than a size 13T shoe. After your child outgrows the largest 7Y shoes, it’s time to move onto adult shoe sizes. Good to know: Youth Shoe Sizes are the same as Men Shoe Sizes!

What is a youth size 7 in men’s shoes?

As youth shoe sizes and men’s shoe sizes follow the same scale, a Youth Size 7 (also denoted as 7Y) is the same size as a Men’s Shoe Size 7.

How Are Boys Shoe Sizes Different From Girls Shoe Sizes?

Boys Shoe Sizes + Girls Shoe Sizes

They aren’t! Girls and boys have similarly-sized feet as they age, up until puberty. That means there’s no need to make a distinction between girls shoe sizes and boys shoe sizes (unlike adult sizes – they differentiate in gender). To find out the boys shoe size to women, measure feet and use this chart. For example a boys 6 in kids equals size 7.5 in women’s shoes.

While you’ll definitely find shoes that are specifically meant for girls and boys – like pink running shoes – they’ll all be sized with unisex sizing. There is no difference in size between girls and boys when wearing toddler shoes or youth shoes.

When To Start Buying Mens Sizes?

This is a common question – and there’s not usually a “hard and fast” answer. There is some overlap between the biggest Youth sizes and smaller men’s shoes.

As a rule, your boy should start looking at purchasing men’s shoes around the age of 12, when he will typically be wearing a size 6Y-7Y shoe and can fit into a men’s size 6-7.

It’s pretty difficult to find men’s shoes under size 6 in most stores, so this is the right time to make the switch.
