A Brief History of US Shoe Sizes

Understanding the history of US shoe sizes can provide valuable insights into the evolution of footwear measurement systems. Let’s take a look at the key milestones that shaped the way we determine shoe sizes today.

Early history and inconsistencies

In the early days of shoemaking, there were no standardized sizing systems. Shoemakers used their own unique measurements, leading to significant inconsistencies. People would often struggle to find shoes that fit properly, resulting in discomfort and ill-fitting footwear.

One of the earliest attempts to standardize shoe sizes in the United States was the Brannock Device, patented by Charles Brannock in 1925. This device measured the length, width, and arch length of the foot, providing a more accurate sizing method.

However, it took some time for this system to gain widespread adoption.

The introduction of standardized sizing

The need for a more consistent sizing system became apparent as the footwear industry grew. In the 1940s, the United States Department of Commerce established a voluntary standard for shoe sizes, known as the “American Standard Lasting Dimensions.”

This standard aimed to create uniformity in shoe sizing across manufacturers.

Over the years, this voluntary standard evolved into the current ASTM International Standard F2412-05, which provides guidelines for shoe sizing and fit testing. Manufacturers now use this standard to ensure that their shoes meet the expectations of consumers.

Modern US sizing system

The modern US sizing system is based on a numerical scale, with each size representing a specific length of the foot. The most commonly used sizing scale for men’s shoes in the United States ranges from size 6 to size 16, with half sizes available for a more precise fit.

It’s important to note that shoe sizes can vary slightly between different brands and styles. It’s always recommended to try on shoes before making a purchase to ensure the best possible fit. Additionally, factors such as foot width and arch height can also affect the fit of a shoe, so it’s essential to consider these aspects when choosing the right size.

How to Measure Feet Correctly

Knowing how to measure your feet correctly is essential when it comes to finding the perfect pair of shoes. Whether you’re using a brannock device, measuring at home, or getting professionally fitted, accurate measurements are crucial for comfort and proper fit.

Using a brannock device

The brannock device is a widely used tool for measuring shoe sizes. Found in most shoe stores, this device provides precise measurements of both length and width. To use it, simply place your foot on the device and align your heel with the heel cup.

Slide the width bar gently against the sides of your foot to determine the width measurement. The length measurement is taken by aligning your longest toe with the corresponding size indicator. Remember to measure both feet, as they may differ slightly in size.

DIY measuring at home

If you don’t have access to a brannock device, you can still measure your feet accurately at home. Start by placing a piece of paper on the floor and standing on it with your heels against a wall. Use a pen or pencil to mark the tip of your longest toe.

Measure the distance from the wall to the mark and repeat the process for the other foot. Take note of the longer measurement and refer to a size chart to determine your shoe size. Keep in mind that this method may not be as precise as using a brannock device, but it can still give you a good estimate.

Getting professionally fitted

For those who want the utmost accuracy and personalized advice, getting professionally fitted is the way to go. Visit a shoe store with knowledgeable staff who can assess your foot size and shape. They will take various measurements, including length, width, and arch height, to determine the best shoe size for you.

Additionally, they can provide recommendations based on your foot type and any specific requirements you may have, such as extra support or orthotics. It’s worth noting that different brands and styles may vary in fit, so trying on multiple pairs is essential.

Factors that affect size measurements

Several factors can influence the measurements of your feet. These include time of day, as feet tend to swell throughout the day, so it’s best to measure them in the afternoon or evening. Additionally, factors like age, weight, and pregnancy can also affect foot size.

It’s important to consider these factors and reassess your shoe size periodically to ensure a comfortable fit.

Standard Men’s Shoe Size Ranges

When it comes to buying shoes, getting the right size is essential for comfort and proper fit. Men’s shoe sizes can vary depending on the brand and country of origin, making it important to understand the standard size ranges. Here is a complete guide to help you navigate the sizing options.

Average foot lengths by size

Men’s shoe sizes are typically measured in length, often represented by a number. The most common sizing system used in the United States is the Brannock Device, which measures both length and width. The average foot length for a specific shoe size can vary, but here are some general guidelines:

US Size Average Foot Length (inches)
6 9.25
7 9.625
8 9.875
9 10.25
10 10.5625
11 10.9375
12 11.25

It’s important to note that these measurements are just averages and can vary from person to person. It’s always best to try on shoes before making a purchase to ensure the perfect fit.

Common width designations

In addition to length, shoe widths also play a crucial role in finding the right fit. The width of a shoe is often indicated using letters, with “D” being the most common width for men’s shoes. Other common width designations include:

  • Narrow (B): Designed for people with narrow feet
  • Wide (E): Designed for people with wide or broad feet
  • Extra Wide (EEE): Designed for people with extra wide feet

It’s important to consider both length and width when choosing the right shoe size to ensure optimal comfort and fit.

Extended sizing options

While standard shoe sizes cover a wide range of foot lengths and widths, some individuals may require extended sizing options. This can include sizes beyond the standard range, such as smaller or larger sizes. Some brands offer extended sizes to cater to a more diverse range of customers.

If you fall outside the standard size range, be sure to explore these options to find the perfect fit for your feet.

Remember, properly fitting shoes can help prevent foot problems and ensure comfort throughout the day. If you’re unsure about your shoe size, it’s always a good idea to visit a professional shoe store and get measured by a fitting specialist.

Achieving the Ideal Fit

When it comes to buying shoes, achieving the ideal fit is crucial for comfort and overall foot health. Here are some factors to consider to ensure you find the perfect fit:

Foot shape and volume

Everyone’s feet are unique, and understanding your foot shape and volume is essential for finding the right shoe size. Some individuals have narrow feet, while others have wider feet. It’s important to measure both the length and width of your foot to determine the appropriate size.

Additionally, consider any specific foot conditions or irregularities you may have, such as high arches or bunions, as these can impact the fit of your shoes.

Sock thickness

Don’t forget to take into account the thickness of the socks you typically wear with your shoes. If you usually wear thicker socks, you might need to go up half a size to accommodate them. On the other hand, if you prefer thin socks or no socks at all, you may need to go down a size to ensure a snug fit.

Intended activity or use

The type of activity or use for your shoes can also affect the fit you should choose. For example, if you’re buying running shoes, you may want to consider a slightly larger size to allow for the natural swelling of your feet during exercise.

Conversely, if you’re purchasing dress shoes for a formal event, a tighter fit may be preferred for a more polished look.

Brand sizing variances

It’s important to note that shoe sizes can vary between brands. A size 9 in one brand may fit differently than a size 9 in another. To ensure the best fit, always refer to the specific brand’s size chart and, if possible, try on the shoes before making a purchase.

Additionally, reading reviews or seeking recommendations from trusted sources can provide insight into any brand-specific sizing quirks.

Trying on tips and break-in period

When trying on shoes, it’s recommended to do so towards the end of the day when your feet are slightly swollen, as this is when they are at their largest. Walk around in the shoes to ensure they provide enough room for your toes to wiggle and that they don’t rub or pinch anywhere.

Keep in mind that some shoes may require a break-in period, so be patient and allow them to mold to your feet over time.

Remember, achieving the ideal fit is key to both comfort and foot health. By considering factors such as foot shape, sock thickness, intended use, brand sizing variances, and trying on tips, you can ensure that your shoes fit you perfectly.

Comparing US Sizes to International Sizing

When it comes to buying shoes, understanding how US sizes compare to international sizing can save you a lot of time and frustration. Different countries and regions have their own unique sizing systems, which can make it difficult to find the right fit.

This guide will help you navigate the world of shoe sizes and ensure that you choose the perfect pair.

UK and European sizes

If you’re familiar with US shoe sizes, you may already know that UK and European sizes are often used interchangeably. However, it’s important to note that they are not exactly the same. UK sizes tend to be smaller than their US counterparts, while European sizes are generally larger.

For example, if you wear a US size 9, you would typically wear a UK size 8 or a European size 42. To convert between US, UK, and European sizes, you can refer to conversion charts available online or consult a shoe size conversion guide.

Asian sizing

Asian shoe sizes can differ significantly from US sizes, so it’s important to be aware of these variations when shopping for shoes from Asian brands or retailers. In general, Asian sizes tend to run smaller than US sizes.

For example, if you wear a US size 9, you may need to go up to a size 10 or even 11 in Asian sizing. It’s always a good idea to check the brand’s specific size chart or reach out to their customer service for guidance when purchasing shoes from Asian retailers.

Conversion charts

Conversion charts are an invaluable tool when it comes to comparing US shoe sizes to international sizing. These charts provide a clear breakdown of how different sizing systems relate to each other, making it easier to find the right fit.

There are many websites and resources available online that offer comprehensive conversion charts. One such website is, which provides conversion charts for US, UK, European, and Asian shoe sizes.

By referring to these charts, you can confidently shop for shoes across different brands and regions.

Remember, it’s always best to try on shoes before making a purchase, especially when shopping online or from international retailers. The conversion charts can serve as a helpful starting point, but individual shoe styles and brands may have slight variations in sizing.


We hope this guide has helped demystify men’s shoe sizing in the US and given you the tools to find your perfect fit. The most important takeaways are learning your exact measurements, accounting for fit factors, and not relying solely on the size marked inside a shoe.
