Short Answer
Complete Explanation
In the context of footwear, letters appearing alongside the numerical size generally indicate the width of the shoe. While the number represents the length of the foot, the letter specifies how much room is available across the ball of the foot and the heel.
- N: Narrow. Designed for feet that are slimmer than the average standard width.
- M: Medium. This is the standard width for most mass-market footwear; it is often the default if no letter is listed.
- W: Wide. Provides additional room for those with broader feet or those experiencing swelling.
- XW / XXW: Extra Wide or Double Extra Wide. These are specialized sizes for significantly broader feet.
In traditional men’s sizing, a different alphabetical system is often used. In this system, letters like D represent the standard medium width, while E, EE (or W), and EEE (or WW) represent progressively wider options. For women, B is typically the standard medium width, with A being narrow and D being wide.
History / Background
The standardization of shoe sizing emerged during the Industrial Revolution as footwear shifted from bespoke, hand-made cobbling to mass production. To ensure a basic level of fit without custom measurements, manufacturers developed grids based on the length of the foot. However, it soon became evident that length alone was insufficient for comfort, as human feet vary significantly in girth and volume. This led to the introduction of width designations, allowing factories to produce a range of lasts (the mechanical forms used to shape shoes) that catered to different anatomical needs.
Importance and Impact
Correct width selection is critical for both comfort and long-term podiatric health. Wearing shoes that are too narrow can lead to the development of bunions, hammertoes, and nerve compression (such as Morton’s neuroma). Conversely, shoes that are too wide can cause the foot to slide, leading to blisters and instability. By providing letter-based width options, the footwear industry enables a broader range of the population to access functional shoes that prevent injury and support natural gait.
Why It Matters
For the modern consumer, understanding these letters is essential for successful online shopping and fitting. Because different brands may have varying definitions of “Standard” or “Wide,” knowing the specific letter code (e.g., knowing that a woman’s ‘D’ is equivalent to a ‘Wide’) allows for more precise comparisons across brands. It also assists individuals with medical conditions, such as edema or diabetes, who require specific volumetric space to avoid pressure points.
Common Misconceptions
A “Wide” shoe is simply a larger size overall.
A wide shoe maintains the same length as the standard size but increases the circumference and volume of the upper and the width of the sole.
Letter codes are universal across all global brands.
While there are general industry standards, different manufacturers may use different letters or proprietary scaling systems to define their widths.
FAQ
What is the difference between 'W' and 'EE'?
Both generally refer to 'Wide,' but 'W' is a common consumer label, while 'EE' is a more technical industry measurement often used in men's footwear.
Do children's shoes have width letters?
Yes, though less common in basic styles, many children's shoes offer 'N' (Narrow) and 'W' (Wide) to accommodate varying growth patterns.
If my shoe has no letter, what width is it?
If no letter is present, the shoe is almost always a 'Medium' or 'Standard' width.
