When it comes to athletic and lifestyle footwear, Nike is one of the most trusted names in the world. But finding the perfect fit isn’t always as straightforward as choosing your usual size—especially with different styles, technologies, and fits across Nike’s vast range of sneakers. Whether you’re shopping for running shoes, basketball kicks, or casual sneakers, this Nike shoe size guide will help you find the ideal pair.
Why Getting the Right Fit Matters
- Comfort: An ill-fitting shoe can cause discomfort, blisters, or pressure points.
- Performance: For athletes, the right fit maximizes efficiency and support.
- Longevity: Shoes that fit well last longer because they wear more evenly.
- Injury Prevention: Proper sizing reduces the risk of foot pain or injury, especially during intense physical activity.
Understanding Nike’s General Fit
Nike shoes are known to run slightly narrow for some people, especially in performance models like the Nike Air Zoom, Nike Free, and Pegasus series. However, many lifestyle sneakers such as Air Force 1s tend to run roomier.
Quick Tip:
If you have wide feet, you may want to size up by 0.5 or look for models available in wide (W) versions.
Step-by-Step: How to Measure Your Feet at Home
What You’ll Need:
- A piece of paper
- A pencil or pen
- A ruler or tape measure
Steps:
- Place the paper on a flat, hard surface (not carpet).
- Stand on it with your heel against a wall.
- Trace around your foot (you can wear socks if that’s how you plan to wear the shoes).
- Measure from the heel to the longest toe (your foot length).
- Measure the widest part of your foot for width reference.
- Repeat the process for your other foot—always use the larger measurement for sizing.

Note: Charts vary by gender, region (US/EU/UK), and even shoe model. Always double-check on Nike’s official size guide.
Tips for Trying on Nike Shoes
- Try them on at the end of the day: Feet swell slightly throughout the day.
- Wear the right socks: Use the type of sock you’ll typically wear with the shoe.
- Walk around: Don’t just stand—walk and pivot to test comfort and movement.
- Check the toe box: You should have about a thumb’s width of space between your longest toe and the front of the shoe.
Sizing Advice by Popular Nike Models
Nike Air Force 1
- Runs large. Many recommend going half a size down for a snug fit.
Nike Air Max
- True to size for most, but consider sizing up if you have wide feet.
Nike React / Infinity Run
- True to size with a sock-like fit. Great for running.
Nike Dunk
- Generally true to size, but can feel narrow in the toe box.
Nike ZoomX Vaporfly
- Race-ready fit—designed to be snug. Some runners prefer half size up.
What About Kids’ and Women’s Nike Sizes?
- Women’s Nike shoes typically run slightly smaller than men’s—about 1.5 sizes apart (e.g., a men’s 7 is a women’s 8.5).
- Kids’ sizes often overlap with adult sizing (a kids’ size 7Y is equivalent to a men’s 7).
When to Consider Wide Sizing
Nike offers wide options (not on all models). If you:
- Have flat feet or naturally wide feet,
- Find regular Nike shoes tight around the midfoot/toe box,
then look for models labeled with “Wide” or “Extra Wide.”
Final Thoughts
Finding the perfect fit in a Nike shoe requires more than just knowing your size—it’s about understanding how different models are designed and how your unique foot shape interacts with them. Always try on when possible, refer to Nike’s official size charts, and don’t hesitate to experiment with half-sizes or width options.
The right fit not only feels better—it performs better.
