What Does The ‘C’ in Shoe Size Mean?

When shopping for shoes, you might notice a letter “C” next to the size — but what does C mean in shoe size? or how wide is C in shoes? The answer depends on whether the shoe is for an adult or a child. In adult footwear, “C” usually refers to width, while in children’s shoes, it stands for child size. Understanding this difference ensures you pick shoes that fit comfortably and support your feet properly.

As an expert guide on shoe sizing and fit, this article explains how “C” varies across age groups, brands, and materials, helping you make a confident and well-informed purchase — whether for yourself or your child.

What Does C Mean in Shoe Size

When it comes to understanding what does C mean in shoe size, the letter “C” simply refers to children’s sizing. It’s used to label shoes designed for babies, toddlers, and young kids before they move into youth or adult sizes. This sizing helps parents easily identify the right fit for growing feet, as children’s shoes have smaller measurements and different proportions compared to adult footwear. Knowing this distinction ensures comfort, proper support, and a better fit for every stage of your child’s development.

How Wide is C in Shoes Sizes In Adult and Children

C Width Shoes Sizes in Adults

In adult shoe sizing, ‘C’ generally refers to the shoe’s width. Shoe widths range from 4A (extra narrow) to 4E (extra wide). To make this clearer, here’s a detailed width guide:

Width Indicator	Women’s Shoe Width Guide	Men’s Shoe Width Guide
4A (AAAA)	Extra Narrow	–
3A (AAA)	Very Narrow	–
2A (AA)	Narrow	–
A	Slightly Narrower than Standard	–
B	Standard Width (Women’s Medium)	Extra Narrow
C	Slightly Wider than Standard	Narrow
D	Very Wide	Standard Width (Men’s Medium)
E	Extra Wide	Slightly Wider than Standard
2E (EE)	Extra Extra Wide	Wide
3E (EEE)	Super Wide	Very Wide
4E (EEEE)	Ultra Wide	Extra Wide

From this chart, we can see that in women’s shoes, a C width is slightly wider than the standard B width. If the B width feels tight, opting for a C width could provide more comfort. Conversely, in men’s shoes, C is narrower than the standard D width. If you find the D width too loose, trying a C width might be the perfect fit.

In contrast, ‘C’ in children’s shoe sizes stands for ‘Child,’ representing sizes for kids aged 2 to 7 years. Children’s feet grow quickly, and the size range from 4C to 13C accommodates different stages of growth.

Choosing Children’s Shoes for Different Stages

4C – 6C: Toddlers (2-3 Years Old)

At this age, children are just beginning to walk, so their shoes need to support their fragile feet. Shoes made of soft materials, such as leather or fabric, with good heel support, are ideal for helping toddlers walk more comfortably.

7C – 10C: Preschoolers (3-5 Years Old)

Preschoolers are full of energy, and their shoes need to be durable and comfortable. Opt for shoes with thicker soles and breathable materials like mesh to keep their feet cool and dry during all their active play.

11C – 13C: School-Age (5-7 Years Old)

By this stage, children participate in a wide variety of activities, from sports to casual play. You’ll find a broader selection of styles, including sneakers, boots, sandals, and casual shoes. Choose the shoe type based on the activity and season.
