For an even more accurate fit, use the brand-specific sizing chart and follow the advice we outline below.

We’ll start with the similarities. Nike and Adidas both provide generic size charts for men, women, and juniors. The two offer conversions from inches and centimeters into US shoe sizes.


Now, let’s talk about the differences. The Adidas size chart shows the UK, EU, and JP (centimeter) sizes for adults, whereas Nike only lists US sizes.

Adidas runs bigger than Nike by up to 5 millimeters. For example, if you’re a women’s size 8 for Adidas, your foot is 9.7-inches long. The same size on Nike tallies up to 9.62 inches, about a millimeter smaller.

The disparity is more evident with half sizes. A women’s 6.5 translates to 9.12 inches on Nike and 9.2 inches on Adidas, which is a fairly big gap.

You can find the Adidas adult sizes here, and kids’ sizes here. For Nike, men can take a look at their sizes here, women here, and juniors here.

Our Tricks to Get the Perfect Fit

Adidas vs Nike Sizing | How Do They Compare in Size? (2)

Shoe sizing seems deceptively simple, but it can require more thought than you think. Try our techniques to lower the chances of getting a bad fit:


  • Never assume or guess what size you are. Measure your feet from the heel to your longest toe. You can do this by tracing your foot on a piece of paper. Make sure you place your heel against the wall and try to be precise if you’re by yourself. Watch this video for more measuring techniques.

  • Even if you’re buying the exact same brand and style of shoes you already own, size yourself. Your footwear can loosen with age, and your feet can change over time with age, illness, or after pregnancy.
  • Remember to consult the size chart of the brand you’re buying from. Don’t risk converting the sizes wrong and having to return your footwear.
  • If you wear insoles to support your feet at work or while you play your favorite sport, don’t forget to try them in your shoes. Your pair might fit perfectly but turn out to be too tight once you slip your inserts in.
  • Socks can be a game-changer for how your footwear fits. Athletes, in particular, should wear their socks of choice with their new shoes. Your everyday socks aren’t the same as lightweight runner’s socks.
  • If your shoes are uncomfortably tight or your feet are slipping out, that means you may need to go up or down a half size or more. Poorly-sized shoes heighten your chances of falls, foot deformities, and pain.
  • Take the time to read the reviews about your shoes before you buy them. Are customers complaining that they’re too narrow or loose? Do many people complain that they’re receiving a size too large or too small?

Pro Tips

  • Measure your feet after a typical day or training session. Your feet will swell throughout the day, particularly if your job or sport puts a lot of pressure on them.
  • For the same reason, try on your new shoes at a similar time. A looser fit first thing in the morning might not correspond to your true size, before your feet swell.
  • Don’t be afraid to test out your footwear thoroughly. Both Adidas and Nike have 30-day return policies. Walk, run, and jump in your new shoes to see if they’re comfortable. Do this indoors on clean or carpeted floors, as you don’t want to void the return policy with damage or dirt.

  • The inches version of the size chart may be too math-heavy for some. If you’re not willing to convert one-eighths and three-quarters into fractions, you might want to measure your feet in centimeters.
