How to Choose Nike Shoe Size and the Most Detailed Nike Shoe Size Chart

Choosing the right Nike size when shopping online can sometimes be confusing, because any sizing mistake can affect how your shoes feel when worn. Let Supersports walk you through the detailed Nike shoe size chart, how to measure your foot length, and accurate size conversions, so you can find a well-fitting pair even when you can't try them on in person.

Nike Shoe Size Chart

When buying Nike shoes online, a size conversion chart helps you find the right size without trying them on. See the official size charts below for Nike men's, women's, unisex, and kids' shoes.

1.1. Nike Men's Shoe Size Chart

The Nike shoe size chart for men converts sizes across the US, UK, EU, and CM/JP systems, along with foot length measurements for easy comparison. When choosing a size, go by the Foot Length column rather than relying only on the size you currently wear, because the same US or EU size can convert differently between brands. Nike also notes that the CM printed on the shoe label or box is not your actual foot length.

For feet with a wider width, some Nike styles come in Wide or Extra-Wide options. According to Nike, the Wide version has a toe box circumference about 6.35 mm larger, and the Extra-Wide about 1.7 cm larger, than the standard fit (Regular).

Nike Women's Shoe Size Chart

The Nike women's shoe size chart covers the US Women, UK, EU, and CM/JP systems, so you can compare sizes across each conversion system. When using the chart, use the women's chart rather than converting directly from men's sizes. If your foot length falls between two sizes, Nike recommends choosing the larger size. If your two feet are different lengths, use the measurement of the longer foot as your reference.

Nike Unisex Shoe Size Chart

Nike shoes in Unisex are designed for both men and women, but the size chart may be presented in US Men's or US Women's sizing. When converting, check how the size is displayed on the product page and compare it with the matching chart to avoid confusing the two systems.

Nike Kids' Shoe Size Chart

Nike divides its size chart for kids' shoes into three groups: Babies & Toddlers (1C–10C), Little Kids (8C–3Y), and Big Kids (1Y–7Y). The size labeling also differs from adult sizes, with C used for younger children and Y for older children.

When choosing a size for your child, measure both feet and use the measurement of the longer foot to check the chart. If the length falls between two sizes, Nike recommends choosing the larger size. In addition to length, have your child wear the socks they plan to use with the shoes when trying them on, so you can judge the fit as close to real use as possible.

How to Choose the Right Nike Shoe Size

To choose the right Nike size, first determine your foot length, then compare it with Nike's size chart. When buying shoes online, you can also use the size finder tool on Supersports to shorten the conversion step.

How to Measure Foot Length to Choose Your Nike Size

It's best to measure your feet at the end of the day while wearing the socks you usually wear with the shoes. Nike recommends measuring both feet, as the length of the two feet may not be exactly the same.

How to Use the Shoe Size Finder Tool at Supersports

If you'd rather not compare each measurement in the size chart yourself, you can use the Find Your Shoe Size tool right on the Supersports product page.

Things to Note When Choosing Nike Shoe Size

If you're buying Nike shoes online, keep these points in mind to choose the right size:

Frequently Asked Questions

How Are Nike Men's and Women's Shoe Sizes Different?

At Nike, men's US sizes are usually 1.5 sizes smaller than women's US sizes. For example, women's US 8 is equivalent to men's US 6.5. For unisex shoes, refer to the product's own size chart.

What Should I Do If My Foot Measurement Falls Between Two Nike Sizes?

If your measurement falls between two sizes, Nike advises choosing the larger size.

How Do I Know If My Nike Shoe Size Is Wrong?

If the toe box feels tight, your heel slips when you walk, the arch of the shoe doesn't sit in the right spot, or the shoes cause rubbing at the heel and ankle, you may be wearing the wrong size or a shoe shape that doesn't suit your foot.

Why Do Nike Shoes in the Same Size Fit Differently?

Because each style has its own design, materials, and intended use. So a running shoe and a lifestyle shoe in the same size can still feel different when worn.

How Can I Check Whether Nike Shoes Fit My Child?

When your child stands in the shoes, check that there is enough room between the toe tips and the front of the shoe to fit a fingertip. Also watch your child as they walk or run; if they seem uncomfortable, the shoes may not fit.
