Adidas Sizing Characteristics
Fractional EU Sizing:
Adidas uses unique fractional EU sizes like 42 2/3 and 43 1/3, which differ from the standard half-size increments used by most other brands. This provides more precise sizing options.
Popular Models:
Ultraboost: Generally true to size with a snug, sock-like fit. Some users with wider feet may need to size up.
Stan Smith: True to size with a classic, comfortable fit.
Superstar: True to size, but some users find them slightly narrow.
Width Considerations:
Adidas shoes generally fit true to size, but some models may feel slightly narrow for wider feet. If you have wider feet, consider sizing up 0.5 sizes or looking for models with a roomier toe box.
Adidas is one of the most popular athletic brands, but their sizing can sometimes differ from other brands like Nike. This guide provides official charts and a conversion tool to help you choose the right size with confidence.

Frequently Asked Questions
How does Adidas sizing compare to Nike?
Generally, Adidas and Nike sizing are very similar. If you are a US size 10 in Nike, you will most likely be a US size 10 in Adidas. The main difference often comes down to the fit and shape of the shoe (the 'last'). Some users find certain Nike models to be slightly narrower than comparable Adidas models.
Are Adidas Ultraboost true to size?
Yes, for the most part, Adidas Ultraboost models fit true to size. They are designed to have a snug, sock-like fit. If you prefer a looser fit or have wider feet, you might consider going up half a size.
What's unique about Adidas EU sizing?
A distinctive feature of Adidas's European (EU) sizing is the use of fractional steps, such as 42, 42 2/3, 43 1/3, and 44. This is different from most other brands that use half or full size steps in their EU charts.
