Shoe Sizing Basics

Shoe Length

Your numerical shoe size, whether you are buying Italian shoes or American shoes, is based on the length of your foot. This is the distance from your heel to your longest toe. It does not account for shape variations or width. Learn how to measure your foot below

Shoe Width

Although most shoes only come in standard widths, there’s an increasing number of brand which are available in wider or narrower styles. Knowing the width of your foot and how it compares to a pair of shoes is essential for a comfortable fit.
Shoe width is usually described with a letter or group of letters, such as “D” or “EEEE.” Sometimes, the letters are replaced by a combination of letters and numbers, such as “4E.” It’s important to note that the width sizing is also dependent on your foot’s length. For instance, if your foot is 3 9/16 inches wide and you wear a size 8, this is considered regular width. However, if you have a foot that is 3 9/16 inches wide and you wear a size 5, you’ll need a wide shoe. Learn all about the importance of width in shoe sizing here

Children’s shoes usually do not come in varying widths.

International Shoe Size Conversion

In the United States, women’s shoes come in whole and half sizes that range from 4 through 12. Men’s shoes have whole and half sizes from 6 through 16.

However, numerical sizes are different in other countries. For instance, a woman who wears a size 6 in the United States will wear a size 4 in the United Kingdom, a size 36/37 in Europe, and a size 23 in Japan.

Finding Your Shoe Size

From infant’s crib shoes to men’s work boots, shoes are sized according to length and width. Understanding how your foot compares to the standard sizes will ensure your shoes fit perfectly, whether you buy them in a real store or order them online.

For sneaker and sports brands like Nike, Puma, Skechers, or Adidas Many people ask “What size would a man be in women’s shoes?” or “how do men’s and women’s shoe sizes actually compare?“.  There’s a 1.5-size difference between the two.  So if a woman wears a women’s size 12.5, that corresponds to a  men’s size 11.
