How Adidas Sizing Works?

Adidas uses US shoe sizes. Adidas sizing can differ slightly depending on the shoe model, so measure your feet for an accurate fit. Adidas’ uniqueness lies in its consistency across shoe models. 

For regular Adidas customers, they’ll likely be the same size in another pair if you’re a size 9.

Another feature that makes Adidas stand out is that it offers shoes in half sizes and widths.

This offers more flexibility and options for those with feet in between sizes or those requiring narrow or wide sizes.

According to Adidas’ standard sizing chart, Adidas shoes fit true to size. Generally, if you’re a size 6 in most brands, you’ll likely be a size 7.

The Importance of Finding the Right Adidas Shoe Size

Finding the perfect fit for your Adidas shoes is crucial for comfort and performance. You need to understand some key points for finding the right shoes. 

  • Adidas shoes generally run true to size. A snug fit can be achieved by going half a size down, but if you prefer a looser fit, consider going half a size up.
  • It needs to be more to know that Adidas shoes run true to size. You need to understand some general aspects to pick the right pair. For instance, Adidas running shoes come in various widths, so choosing the right width for your foot is important.
  • When finding the right fit, aim for walking shoes with a thumb’s width between your longest toe and the front of the shoe.
  • Adidas provides a sizing chart that considers foot length and width to help customers find the right size.
  • It’s crucial to measure your feet when buying shoes. This will help you choose the right size and avoid problems.
  • Ill-fitting shoes can lead to painful medical conditions like arch pain, neuromas, and Achilles tendonitis. They can also affect other body parts, including your knees, back, and neck.
  • Remember, comfort is key when choosing footwear. If you’re experiencing persistent problems, it might be best to consult a footwear specialist or consider a different style or brand.

As I mentioned before, Adidas shoes are true to their shoes. You will likely get the best fit if you choose an Adidas shoe size based on your foot measurement.

Sizing shoes can be a challenge, especially online. Some brands run small or large, requiring you to adjust your usual size. However, Adidas simplifies this. 

Here are some examples of specific Adidas shoe models and their fit based on my personal experience and feedback from other customers:

Adidas Superstars: These iconic shoes tend to run true to size. Many customers have noted that they didn’t need to adjust their usual shoe size for a comfortable fit.

Specific sizes and feedback:

  • Size 9: For most, including myself, size 9 in Adidas Superstars fits true to size. However, some customers have found them to be slightly small.
  • Size 9.5: This size tends to run slightly small for some customers. You might consider sizing up if you’re between sizes or prefer a more relaxed fit.
  • Size 10: Many customers have found that size 10 fits true to size. It offers a comfortable fit without needing to adjust your usual shoe size.
  • Size 10.5: Some customers have reported that this size runs slightly small. If you’re considering size 10.5, you might want to try them on in-store if possible or consider sizing up for a sure fit.
  • Size 11: Size 11 generally fits true to size according to some customer feedback.

Adidas Stan Smiths: Stan Smiths are also known for their true-to-size fit. They’re designed with a slightly wider toe box, making them a great option for those with wide feet.

Specific sizes and feedback

  • Size 9: In my experience, a size 9 in Adidas Stan Smiths fits true to size. However, a few customers have reported them to be slightly small.
  • Size 9.5: For some individuals, size 9.5 tends to run a tad small. If you’re considering this size, it might be worth trying them in-store or considering half a size up.
  • Size 10: Many customers report that size 10 in Stan Smiths fits true to size, offering a comfortable fit without needing to adjust your usual shoe size.
  • Size 10.5: Some customers have found that size 10.5 runs slightly small. If you’re leaning towards this size, it may be beneficial to try them on beforehand or consider sizing up.

Adidas Ultraboost: Known for their comfort, Ultraboosts generally run true to size. However, some customers have suggested going half a size up if you prefer more room in your running shoes. Here’s a brief breakdown based on specific sizes:

  • Size 9: It fits true to size, but it can be small.
  • Size 9.5: Runs a bit small for some customers.
  • Size 10 & 11: Both these sizes typically fit true to size for most people.

Do all Adidas shoes fit true to size?

Adidas shoes fit true to size

Yes. It’s generally accurate to say that most Adidas shoe models adhere to standard sizing. However, it’s important to note that certain models may run slightly larger or smaller than the typical fit. The perfect fit can depend on several factors.

Different Adidas shoes feature diverse materials in their uppers, soles, and midsoles, each serving unique purposes. 

For Example, the Adidas Ultraboost, a runner’s favorite, boasts lightweight and stretchy uppers for flexibility during runs. 

The iconic Superstar model features stiffer leather uppers for a more structured fit.

While Ultraboost and Superstar models are usually true to size, some factors can enhance comfort. Choosing a size larger for running shoes like the Ultraboost may enhance foot movement during runs.

A half-size larger could be more comfortable for those with wider feet, especially with stiffer shoes like the Superstar. I also prefer a roomier fit for my running shoes, which allows for greater comfort during jogging or other athletic activities.

Adidas Shoes Sizing Guide

Adidas models fit differently due to variations in design and materials. If the shoes don’t fit well, don’t hesitate to return them and try another size or model. Comfort should always be your top priority when choosing footwear.

  1. Never Assume: Even if you’ve been a loyal customer of Adidas shoes for years, don’t assume that a particular size will always fit you. Our feet can change over time due to various factors, including medical conditions like diabetes or life events like pregnancy. Therefore, it’s important to re-measure your feet when buying new shoes.
  2. Precision is Crucial: Small differences in measurement can significantly affect how a shoe fits and feels. Hence, measuring your foot’s important to be as accurate as possible.
  3. Factor in Orthotics: If you wear orthotics for a specific foot condition, remember they take up more space inside your shoe than regular insoles. You might need to consider a larger size to accommodate them comfortably.

Identify a Bad Fit: Be aware of signs that indicate your shoes don’t fit properly. If your shoes slip off while walking, they could be too big. Alternatively, the shoes may be too small if you feel your toes are compressed or squeezed. Persisting with ill-fitting shoes can lead to discomfort and even serious foot issues.

What is the best way to determine your Adidas shoe size?

You should always try on your shoes in shoe stores to find your ideal fit. However, it is not always possible to do so, and some people prefer to purchase shoes online because of their comfort. To determine the right size for your feet, measure your foot at home and refer to the Adidas shoe size charts. Check below how you can determine your shoe size.

  1. Measure Your Feet: Use a ruler or tape measure to determine the length of your feet from heel to toe. Always measure both feet and use the larger measurement as your guide.
  2. Refer to the Adidas Size Chart: Each brand has its unique sizing chart, so always consult the Adidas size chart to find your corresponding shoe size. Remember that sizing standards may vary depending on the country where the shoe is manufactured.
  3. Consider the Intended Use of the Shoe: The shoe’s purpose can affect how it should fit. Some Adidas shoes are designed to fit snugly for better performance, while others are more loosely fitted for comfort.
  4. Read Customer Reviews: Look for reviews from other customers who have purchased the same shoe model. They often provide valuable feedback about the sizing, such as whether the shoe runs true to size or if they had to size up or down.

Try on the Shoes: If possible, try the shoes in person before purchasing. Walk around in them to gauge how they feel. Ensure enough room for your toes to wiggle without the shoe slipping off.

How to Measure Your Shoe Size When Buying Adidas

Adidas shoes measure

Determining your Adidas shoe size requires a simple process you can do at home. Here’s how you can achieve it:

  1. Prepare a flat surface and a blank piece of paper: Position the paper near a wall on the flat surface.
  2. Stand on the paper: Ensure your heel is against the wall for accurate measurement.
  3. Mark your foot length: Use a pencil to mark where your toes end on the paper.
  4. Measure your foot: Measure from the end of the paper to the mark you created with your pencil. This measurement is your foot length.
  5. Refer to the Adidas size chart: Match your foot length to the corresponding shoe size on the Adidas size chart. You can find this chart on the product page of the shoe you’re interested in or on the Adidas official website.

Here are some extra tips to ensure a more accurate and simpler measuring process:

  • Ask for Help: Having someone else trace the outline of your foot can lead to more precise measurements.
  • Consider Your Socks: Remember to factor in the extra room you’ll need for your socks. Wearing your usual socks while measuring can enhance accuracy when referencing the Adidas shoe size charts.
  • Time Your Measurements: Measuring your feet at the end of the day is recommended, as feet tend to swell after prolonged use. This will provide a more accurate size for all-day comfort.

Using the Adifit Insole for Kids

The Adifit Insole by Adidas is a handy tool designed to help parents accurately determine their child’s shoe size. By placing the insole in the shoe and having your child step on it, you can easily see if the shoe fits correctly based on the marked lines.

This reusable and portable tool simplifies shoe shopping and helps ensure your child’s feet have the space they need to grow healthily.

Adidas Shoe Size Chart

You can check the Adidas official website for the short-size chart. And find the perfect size shoes for you. 

Adidas offers comprehensive shoe size charts for both men and women. These charts are essential to help you find the perfect fit when shopping for Adidas shoes.

Here are some details from the Adidas shoe size chart:

Men’s Adidas Shoe Size Chart:


The chart continues in this pattern, adding 0.5 to the US size, 0.5 to the UK size, about 0.6 to the EU size, and 0.5 to the CM measurement with each step.

Women’s Adidas Shoe Size Chart:


Like the men’s chart, the women’s chart also progresses by adding 0.5 to the US and UK sizes, about 0.6 to the EU size, and 0.5 to the CM measurement with each step.

It’s important to note that there’s typically a 1.5-size difference in length between women’s and men’s shoes. For Example, a women’s size 8.5 would be equivalent to a men’s size 7. However, the width size usually remains the same.

Using these charts and considering these conversion tips can help ensure you select the right size when buying Adidas shoes.

Tips for Finding the Right Adidas Fit

Finding the Right Adidas Fit

You might face some problems when measuring your shoes at home. That’s why I have shared some tips below to find the right Adidas fit.

  • Regular Measurements: Even as an adult, your foot size can change due to weight fluctuation, aging, and fluid retention. Measuring your feet before buying each new pair of shoes is recommended.
  • Measure in the Evening: Your feet expand throughout the day due to activity. Therefore, measurements taken in the evening tend to be more accurate.
  • Consider Both Feet: Both feet can have different lengths. Always go with the measurement of your larger foot for the best fit.
  • Wear Appropriate Socks: The socks you plan to wear with the shoes can affect their fit. Make sure to wear them when trying on shoes or taking measurements.
  • Test for Toe Room: Ensure enough room in the shoes for your toes to move around comfortably. A pair of shoes that is too tight or too loose can cause discomfort and blisters.
  • Walk Around: Test the fit of the shoes by walking around in them. Check for any slipping or rubbing, and make sure your heel stays in place.

Check the Width: Adidas shoes come in different widths. Your feet should be the right width for comfort and to avoid injury.

Things Besides Size That’ll Affect Your Adidas Shoe Fit

Besides sizing, other factors can also influence the fit. I have gathered important information on these factors just for you.

  1. Materials: A shoe’s construction materials significantly impact how it fits. I’ve found that shoes made from elastic or flexible substances often provide a different fit than those crafted from more rigid materials. This is because stretchy materials can mold to the shape of your foot, which might give the impression of a larger shoe.
  2. Design: Adidas shoe models have unique designs that influence their sizing. Some models are deliberately designed to run larger or smaller than the standard shoe size. Trying on different styles to find the best fit is a practice that has served me well.
  3. Product Type: Sneakers or running shoes can vary in fit depending on the product type. Each shoe type caters to specific needs and thus offers unique dimensions. I always refer to the specific size chart provided for each shoe type for an accurate fit.
  4. Brand Differences: From my experience, shoe sizes are not uniform across all brands. If you’re used to a particular size in a different brand, it may not translate directly to the same size in Adidas. I recommend measuring your foot and following the Adidas size guide when switching brands.
  5. Foot Conditions: Any foot conditions or deformities you might have, like bunions or hammer toes, can affect how a shoe fits. Likewise, underlying health issues such as arthritis or diabetes can alter the size and shape of your foot, thereby impacting the shoe fit. I’ve learned to take these into account when choosing shoes.
  6. Time of Day: Interestingly, the day can influence your shoe size. Our feet swell slightly as the day progresses, resulting in a larger foot size by evening. So, I usually measure my feet later in the day for the most accurate measurements.
  7. Shoe Shape: The shoe’s shape, whether it’s wide, narrow, or neutral, can also impact the fit. I’ve found that some people might prefer a wider shoe for comfort, while others might lean towards a narrower fit for support.
  8. Arch Type: Your arch (high, low, or neutral) can also influence the fit. I’ve found certain Adidas models more comfortable than others due to their compatibility with my arch type.
  9. Purpose: Your intended use for the shoe – whether it’s for running, walking, casual wear, or sports – can influence the fit. Each activity requires different levels of comfort, support, and flexibility, which I’ve always taken into consideration during my purchases.
  10. Shoe Depth: The depth of the shoe can make a significant difference, especially if you need to accommodate orthotics or require extra room for any reason. I’ve noted that some Adidas shoes come with removable insoles, providing additional depth if needed.

How to solve common Adidas shoe sizing problems

Even if you know the answer about do Adidas shoes run big or small. You will face common problems sometimes. You may want to consider a different brand or style if you’re experiencing continuous problems. Here are some common issues with Adidas shoe sizing and potential solutions:

  • Shoes Feel Too Tight: If your Adidas shoes feel too tight, try loosening the laces or adjusting the straps, if they have any. You could also consider wearing them briefly to break them in gradually. However, if the shoes persistently feel too tight, you might need to size up by half a size.
  • Shoes Feel Too Loose: If your shoes feel too loose, attempt tightening the laces or adjusting the straps. If this doesn’t improve the fit, it may be necessary to size down by half a size.
  • Shoes Causing Rubbing or Blisters: If your Adidas shoes are causing discomfort or blisters, consider wearing thicker socks or applying moleskin or other padding to the problem areas. Adjusting the laces or straps for a more secure fit might also help.
  • Shoes Feel Too Narrow or Wide: If your Adidas shoes feel too narrow or wide, it might be worth trying a different width size. Alternatively, adjusting the laces or straps might provide a better fit.

Shoes Feel Uncomfortable: If your shoes are uncomfortable, it could be due to insufficient arch support or cushioning. In this case, you might try shoes with more support or cushioning or add insoles for extra comfort.

Do Adidas Basketball Shoes Run Big Or Small

The Importance of Finding the Right Adidas Shoe Size

Adidas basketball shoes usually align with standard shoe sizes, providing a true-to-size fit. However, the precise fit can vary depending on the specific model and your personal comfort preferences. It’s always best to try on shoes before purchasing or consult the brand’s unique sizing chart to ensure proper fit.

Key points from my research include:

  • Adidas shoes typically follow the Brannock Standard, a universally recognized measure in the footwear industry for determining shoe size.
  • While Adidas shoes generally offer a true-to-size fit, some individuals may find it more comfortable to opt for a half-size larger, especially when it comes to basketball shoes.
  • Adidas shoes are usually slightly larger than Nike shoes. While Adidas adheres to true-to-size measurements, Nike shoes often run half a size smaller than their listed sizes.

It’s essential to remember that the ultimate goal is to find shoes that provide both comfort and necessary support. If you find yourself between sizes, it may be beneficial to try both and choose the best fit.

Do Adidas Shoes Run Big Or Small Compared To Nike

Adidas shoes generally run true to size compared to Nike shoes. There are a few factors to consider when comparing Adidas shoes to Nike shoes in terms of fit:

  1. General Fit: Adidas shoes are generally perceived to have a slightly narrower fit than Nike shoes. They typically offer a snug feel around the midfoot and heel, benefiting some users, particularly during sports activities. Nike shoes often provide a more spacious toe box, allowing more room for toe movement.
  2. Sizing Consistency: The consistency of sizing can vary between brands and even within different models of the same brand. This means that a Nike shoe might fit differently than an Adidas shoe, even if labeled as the same size. Fitting a shoe to your foot shape and size requires trying each individually.
  3. Arch Support and Pronation Control: Adidas and Nike have shoes with varying degrees of arch support and pronation control features. Depending on your specific foot needs, you may find one brand’s shoes more comfortable and supportive than the other. Remember your foot type (neutral, overpronation, or underpronation) and look for shoes that address your needs within each brand’s lineup.
  4. Ankle and Heel Support: Some users may find that Adidas shoes offer superior ankle support, while others might prefer Nike’s cushioning and stability in the heel area. This can be subjective and may depend on personal preferences and foot conditions.

Try Before You Buy: Given the differences in fit and sizing between Adidas and Nike shoes, it is highly recommended to try on both brands in-person before purchasing. Visiting a store and trying on various models will allow you to assess the fit, comfort, and support each brand provides based on your specific foot shape and size.
