Adidas Sizing Myth vs. Reality

Contrary to the myth that Adidas shoes run smaller than true sizes, my experience shows that Adidas generally adheres to industry standards in their sizing guides. However, sizes can vary across different models and collections.

Additionally, individual preferences and foot shapes play a significant role in choosing the right Adidas footwear. Therefore, it’s important for customers to consider factors like specific models and their own foot dimensions to find the best fit.

Does Adidas Run Big or Small?

Adidas shoes are generally true to size, meaning if you buy a pair according to your foot measurement, they should fit perfectly. Unlike some brands where you might need to size up or down, Adidas typically aligns with standard sizing, making it more convenient, especially for online shopping.

In my experience and based on customer feedback, Adidas shoes consistently fit true to size across various models, eliminating the need to guess about sizing adjustments. Here are examples of specific Adidas models and their fit:

1. Adidas Ultra Boost Sizing

I own several pairs of Ultra Boost shoes, and they fit me perfectly in my usual size. However, some customers have reported that they run slightly small, so it may be worth trying a half size up.

2. Adidas NMD Sizing

I own and have tried on NMD shoes in stores, and I found that they fit me true to size. However, some customers have reported that they run slightly small or narrow, so it may be worth trying a half size up or opting for a wider width.

Please note that, apparently, the NMD S1 may run half a size big! So try to choose a size or half size down and see how it fits your feet.

3. Adidas Stan Smith

I’ve also owned a pair of Stan Smith sneakers, and I found that they ran slightly big for me. I had to go down a half size to get a better fit. Other customers have reported similar experiences.

Again, it’s important to note that everyone’s feet are different, and what works for me may not work for someone else. It’s always a good idea to try on shoes or consult customer reviews before making a purchase, especially if you’re unsure about the sizing.

Are All Adidas Shoes True to Size?

do adidas run big

Adidas offers a wide range of styles for various purposes, from sports-specific to everyday wear, and their shoes are generally true to size. However, the fit can vary due to different materials used in uppers, soles, and midsoles.

For instance, the stretchy uppers of the Adidas Ultraboost might require going a size up for extra room during running, while the stiffer leather uppers of the Superstar model might need a half-size larger for those with wider feet.

It’s important to consider your specific needs and preferences, like extra space for athletic activities, when choosing your Adidas shoe size.

The Fit of Adidas: Model by Model Breakdown

I’ve explained the Adidas Ultraboost, Stan Smith, and the MND above. Here are other popular Adidas shoe models and their sizing information!

  • Superstar. I find that these shoes also tend to run slightly large. If you prefer a snug fit, you can try to go down a half size or choose. A lot of customers find this model to be true to size, though.
  • Yeezy. Sizing for Adidas Yeezy shoes can vary depending on the specific model. Some Yeezy models, like the Yeezy Boost 350 V2, are known to run small, so it’s recommended to go up a half size or more.
  • Gazelle. These shoes tend to run true to size, but some people with wider feet may need to go up a half size for a comfortable fit.
  • Adidas Continental 80. These shoes have a true fit, but you may need to go up a half size if you find the initial size too narrow.
  • Samba. These shoes have a slightly narrow fit and can run small, so some people go up a half size for a more comfortable fit. If it is still too small for you, try going up a full size.
  • Adidas Originals Campus. Some people find that it has a snug, true-to-size fit. If you don’t like it, you may need to go up a half size for a better fit or wear thinner socks.

How Adidas Men’s Sizes Compare to Women’s

In my experience with Adidas, men’s sizes are generally larger than women’s. Women’s sizes are designed to be slightly narrower with a more tapered heel to suit the female foot structure, while men’s sizes are roomier for broader feet.

For example, a woman’s size 8 in running shoes often corresponds to a men’s size 6.5 to 7. In measurements, a women’s size 8 is about 24.6 cm (9.7 inches), compared to men’s 6.5 to 7 at approximately 28.4 cm (11.2 inches).

It’s best to measure your foot length and refer to the Adidas-specific shoe size chart for accurate sizing.

Adidas Children’s Sizes: Do They Run True to Size?

Children’s Adidas shoes don’t follow adult sizing, as they’re designed for developing feet with room for growth. It’s important to consult specific sizing guidelines for each model, as they can vary. Generally, Adidas children’s sizes are true to their measurements.

To help you choose the right size, I’ve created a table to guide you in selecting Adidas kid shoes that fit just right.

Things Besides Size That Will Affect Your Adidas Shoe Fit

Size is crucial, but other factors also significantly influence the fit of your Adidas shoes:

  • Materials: Materials like Primeknit and Mesh adapt well to foot shapes and offer flexibility, while synthetic leather provides durability but less stretch.
  • Shoe Models: Different Adidas models have slightly varied sizing. Running shoes often offer a more precise fit for performance, while lifestyle models like the Grand Court prioritize style and may feel more relaxed.
  • Arch Support: The type of arch support affects shoe fit and shape. High arch shoes can feel tighter, especially in the midfoot, while neutral arch support follows standard sizing. Low arch designs offer more room for various foot shapes. High arches can make you appear taller, but it’s important to choose a size up for comfort.

Consider these factors alongside size for the best fit in Adidas footwear.

Expert Tips on Selecting The Right Size in Adidas

Adidas provides a comprehensive sizing chart with measurements in inches and centimeters, covering men’s, women’s, and kids’ sizes in UK, US, JP, and EU formats. To ensure the correct fit, measure both the length and width of your feet using the methods I recommend.

Method 1

The first method involves measuring your foot length, which determines a shoe size. Complete these steps to discover your size:

  1. Take a blank piece of paper and lay it on the floor against the wall.
  2. Stand on the paper with one foot so that your heel touches the wall lightly.
  3. Mark the spot on the paper where your longest toe ends.
  4. Measure the distance between the marked spot and the wall to determine your foot length.
  5. Repeat the process with your other foot.
  6. Take both measurements and compare them with the Adidas sizing chart to determine the correct shoe size for you.

Method 2

Shoe size typically reflects length, but width is crucial for a comfortable fit. Ill-fitting widths can cause foot pain, so accurate foot measurements are essential.

Here’s a concise method to measure both length and width:

  1. Tape a blank piece of paper to the floor.
  2. Trace your foot on the paper, possibly with someone’s help for precision.
  3. Repeat with the other foot.
  4. Measure the length from your longest toe to heel and the width at the foot’s widest part.
  5. Compare these measurements with the Adidas sizing chart for the correct size.

If your foot width is disproportionate to its length, don’t automatically opt for a larger size. Instead, choose shoes designed for extra space, like some Adidas Cloudfoam models, which might require a half or full size smaller due to their stretchable cushioning.

Common Problems with Adidas Shoe Sizing and Solutions

do adidas run big
  • Shoes Too Tight: Loosen laces or straps, wear them briefly to break in, or consider going up a half size if they remain tight.
  • Shoes Too Loose: Tighten laces or straps, or go down a half size if they still feel loose.
  • Rubbing/Blisters: Wear thicker socks, apply moleskin or padding to problem areas, or adjust laces or straps for a better fit.
  • Shoes Too Narrow/Wide: Try a different width, or adjust laces or straps for a more comfortable fit.
  • General Discomfort: If discomfort is due to poor arch support or cushioning, opt for shoes with more support, add insoles, or choose models with better cushioning.

Questions and Answers

1. Do different Adidas styles fit differently?

Yes, different Adidas styles can fit differently due to variations in their design and materials used. For example, some styles may have a wider or narrower toe box or a more cushioned or minimalist sole. These differences can impact how the shoes fit and feel on the feet.

2. How do I choose the right size when shopping online?

You can follow my guide above, especially the part about how to determine your Adidas shoe size and how to convert your feet measurements. Check the chart as well and find out if the model fits true to size, runs big, or runs small.

Also, do not forget to look for free returns in case they do not fit. If they are indeed free, order multiple sizes, especially if you are still unsure, and return the ones that don’t fit.

3. Do Adidas run big compared to Nike?

Generally speaking, Adidas shoes run bigger than Nike. I believe that Nike shoes are 5 millimeters smaller than Adidas’ counterparts.

If your usual shoe size for Nike is 30, then you may want to check out one half-size smaller for the Adidas brand. But to be sure, you need to double-check by trying them both in your favorite shoe stores.

4. What are the best Adidas running shoes?

Adidas Ultraboost 22

Provide dreamy cushioning and a nice grip. It is also super lightweight! But this model does get a bit tight on the toe-box, so not suitable for wide feet.

Adidas Solarglide 5

These are my favorite running shoes for when I want to traverse uneven terrain. It is comfy and grippy. But some reviewers say that this mode is a tad heavier and can be a bit pricey.

Adidas Adizero Adios Pro 3

The right shoe fit enhances comfort, performance, and protection from health issues. Adidas generally offers true-to-size shoes, making it easier to find a fitting pair, even online, with correct measurements.

The Adizero Adios Pro 3 is ideal for marathons, offering excellent ventilation, cushioning, and energy retention, along with a good grip. However, they can be pricey, and the heel fit might be tricky. Despite Adidas’ true-to-size reputation, this model’s cushioning may affect sizing, so trying them on before purchasing is advisable.


Getting the right shoe fit ensures you remain comfortable in whatever you do, boosts your performance in sports, and protects you from health issues stemming from poor balance and inadequate support.

Fortunately, Adidas makes it easy to find the right shoe by making their shoes true to size. As long as you take your measurements correctly and keep the various tips in mind, you’ll be able to get a fitting pair even when you buy online.
