Adidas Shoe Size Guide

Complete sizing charts and fit guide for all Adidas shoes including Ultra Boost, Stan Smith, Superstar, and NMD

Quick Answer: Adidas shoes generally run large and wide compared to other brands. Most people size down 0.5 sizes for Adidas athletic shoes. However, fit varies by model - some lifestyle shoes like Stan Smith fit true to size. Adidas also offers more wide-width options than most brands.

Adidas Sizing Overview: Does Adidas Run Large or Small?

Adidas is known for having more generous sizing compared to competitors like Nike. Understanding how Adidas sizing works across their different product lines will help you find the perfect fit and avoid common sizing mistakes.

General Rule: Adidas running and athletic shoes typically run 0.5 to 1 full size larger than standard US sizing, and they tend to run wider than average. This means if you normally wear a size 10 in Nike, you might need a 9.5 or even a 9 in Adidas. However, lifestyle and casual models like Stan Smith and Superstar often fit true to size.

Adidas has made efforts to standardize their sizing in recent years, but significant variation still exists between different shoe lines and models.

Adidas Sizing by Shoe Type

Running Shoes (Ultra Boost, Solar Boost, Adizero): Adidas running shoes generally run large and wide. The Ultra Boost in particular is known for running a half size to full size large. The Primeknit upper is very stretchy and accommodating. If you have narrow feet, definitely size down. For normal to wide feet, sizing down 0.5 is recommended.

Basketball Shoes (Harden, Dame, Trae Young): Adidas basketball shoes fit more true to size compared to their running line, but still tend to run slightly large. The Harden series runs true to size with good width. Dame and Trae Young models fit true to size but with a more performance-oriented snug fit.

Lifestyle/Casual (Stan Smith, Superstar, Samba): These classic Adidas models generally fit true to size. Stan Smiths have a narrow to medium width and fit true to size for most people. Superstars run slightly large and wide - many size down 0.5. Sambas fit true to size with a snug, performance fit.

NMD and Yeezy Line: NMD models run large - sizing down 0.5 to 1 full size is common. Yeezy sizing varies by model: Yeezy 350 V2 runs small (size up 0.5), Yeezy 700 runs true to size, and Yeezy slides run very small (size up 1-2 sizes).

Training and Soccer: Adidas training shoes fit true to size with good stability. Soccer cleats like Predator and Copa fit true to size but narrow, as they're designed for performance fit.

How to Find Your Perfect Adidas Fit

Measure Your Feet

For the most accurate Adidas size, measure your feet in centimeters. Stand on paper, trace your foot, and measure from heel to longest toe. Compare this measurement to the Adidas size charts above. Adidas tends to run generous, so if you're between sizes, go with the smaller size for most models.

Consider the Model

Adidas sizing varies significantly by model. Before purchasing:

Pro Tip: Adidas offers more wide-width options than most brands. Look for shoes marked with "Wide" or specific width designations if you have wider feet.

Adidas Width Options

One of Adidas's strengths is their commitment to offering wide-width options. Many Adidas shoes are available in:

If you have wide feet and find most athletic shoes too narrow, Adidas is an excellent brand choice. Their standard width already accommodates wider feet better than competitors.

Popular Adidas Models and Their Fit

Ultra Boost

The Ultra Boost is one of Adidas's most popular running shoes but runs notoriously large. The Primeknit upper is very stretchy and forgiving. Most people need to size down 0.5, and those with narrow feet often go down a full size. The 2024 Ultra Boost models have slightly improved sizing but still run large.

Stan Smith

The classic Stan Smith fits true to size with a narrow to medium width. These leather sneakers don't stretch much, so don't size down hoping they'll stretch out. If you're between sizes, go up for comfort. Stan Smiths run narrower than most Adidas shoes.

Superstar

Superstars run large and wide, similar to the Ultra Boost. Most wearers size down 0.5. The shell toe design creates a roomier fit in the toe box. These are great for wider feet at true size, but narrow feet should definitely size down.

NMD

NMD models run very large. Sizing down 0.5 is minimum, and many people go down a full size. The Primeknit upper is extremely stretchy. If you have narrow feet, you'll definitely need to size down significantly.

Yeezy Line

Yeezy sizing is complicated and varies by model. Yeezy 350 V2 actually runs small (opposite of most Adidas) - size up 0.5. Yeezy 700 fits true to size. Yeezy slides run 1-2 sizes small. Always check the specific Yeezy model sizing before purchasing.

Common Adidas Sizing Questions

Should I size up or down in Adidas?

For most Adidas athletic shoes (Ultra Boost, NMD, Superstar), size down 0.5 from your normal size. For lifestyle shoes like Stan Smith, stick with your true size. Yeezy 350 is the exception - size up 0.5.

Are Adidas and Nike sizes the same?

No, Adidas runs larger than Nike. If you wear a size 10 in Nike, you'll likely need a 9.5 or even 9 in Adidas athletic shoes. Adidas is more generous in both length and width.

Do Adidas shoes run wide?

Yes, Adidas shoes generally run wider than Nike and many other brands. This makes them an excellent choice for people with wider feet. Standard width Adidas often feels like wide width in other brands.

Do Adidas shoes stretch?

Adidas shoes with Primeknit uppers (Ultra Boost, NMD) stretch significantly with wear. Leather models like Stan Smith stretch slightly but minimal. Don't buy too-small shoes hoping they'll stretch - they're already generous in sizing.

What size should I get in Adidas if I'm between sizes?

Since Adidas runs large, go with the smaller size if you're between sizes in most athletic models. For Stan Smith or other leather lifestyle shoes that fit true to size, go with the larger size for comfort.

Adidas vs. Competitors: Compared to other brands, Adidas runs 0.5-1 size larger than Nike, about the same as Puma, and slightly larger than New Balance. Adidas consistently runs wider than all major competitors.
