What Does CD Mean in Shoe Sizes? Here is the Answer!

Are you 100 percent confident to buy the right pair of shoes which fit your foot size? You may know your shoe size is number 7, but just the foot length is not enough. Sometimes it is more complicated than you think. If you ever look at the footwear indicators, there must be some letters such as AAA, B, or even C/D. So what does C/D in shoe size mean? Does it really have a size C/D in shoes? Actually, C/D size is a measurement of your foot. You can have a rational explanation here and how to find a perfect shoe size based on this.

C/d Shoe Size Meaning

A pair of shoes will be measured in two parts: the letter part and the number part. For example: A7, D8, EE9, etc.

We usually pay more attention to the number part, so you know your shoe size is a 6, or a 7, but few people are aware of the letter part. In fact, the number shows your foot length, and the letter illustrates how wide your foot is. If this section is missing, your shoe measurements aren’t quite right.

In short, C/D is one of the indicators to measure the width of your feet. They use a letter system from A to E to describe the shoe width. There are different levels for each letter to illustrate the specific figure. For example, A is the smallest size. Still, some people who have narrower feet than others need another parameter to measure their shoes.

Therefore, they have AAA, or even AAAA for narrower feet than size A. Similarly, the EE or EEE indicator is used for people who have wider feet than E. This method is the same as the size measurement in clothes with XS, XXS and XL, XXL.

C/D is used to measure the feet, which have a combination of two different sizes. There are many people who have unbalanced foot parts, such as the heel being larger than the instep.

Shoe size C/D means the heel is C, while the ball of foot is D. People wearing shoe sizes C/D are frequently misidentified as size C or size D. This parameter assists people with unusual foot sizes in finding the right shoes that fit properly and prevent injury while moving.

The Difference in Size C/D Meaning in Men’s and Women’s Width

It’s important to note that the parameter of width has different meanings in men’s and women’s shoes. In men’s shoes, a size D is average, but it is considered a wide size in women’s shoes.

Men’s feet are wider than women’s. As a result, the parameters AA or AAA are unlikely to be found in men’s footwear, but EE or EEE is commonly found. The average shoe width for men is D. C/D denotes a person with narrower feet than the rest of the group.

Women with a C/D size, on the other hand, will be considered having wide feet because the average female size is B. Women’s shoe sizes typically range from AAA to D, though some people with extra wide feet may require a size E. Some shoe brands alter their measurements to make it easier for women with wide feet to find the right shoes.

How to Measure Shoe Width

If you only know your shoe size by length and don’t know your foot width, you’ll need to learn how to measure your foot width at home. The method is simple; all you need is a pen, a piece of paper, and a measuring tape to determine the width of your feet.

  • Step 1: Take off your shoes and socks (be sure you measure the bare foot)
  • Step 2: Draw an outline of your foot on the paper. Try to draw as close as you can.
  • Step 3: Measure the widest part of your foot with the tape.

With the final number, you can compare it to the shoe width measurement chart to determine which size best fits you. And from now on, wherever you go shopping for new shoes, remember to look at the letter part in front of the number to make sure you get the right one. 

Sometimes, the shoe brand will not show the product’s width size, but you can always find it online just by checking its description.

Does Shoe Width Change Over Time

The interesting news is that your shoe width will not last indefinitely. It changes depending on your age or health condition. When you are older, all your measurements will be different, including your feet. 

Some diseases, such as obesity or diabetes, also affect the width of your feet because you gain weight. In these situations, you can decrease your feet size by losing weight or controlling the insulin resistance in your body. As a result, maintaining good health is the best way to keep your foot width in check.


Finding the right shoes, especially running or training shoes, that fit you in both length and width is critical to your health and performance. Hopefully, this article on what C/D means will answer questions you have about the width of your shoe.

You now understand that C/D is a parameter in the foot width measurement system that determines the combination of a heel in size C and a ball of foot in size D. From this acknowledgement, you can determine the width of your feet and choose a perfect pair of shoes.
