What Does B in Shoe Size Mean? Complete Guide for the Perfect Fit
When I first began shopping for shoes online, all those letters after shoe sizes boggled me. What does B refer to in shoe size? Does it apply to men and women alike? After years of assisting customers on how to find their ideal fit at Ardur, here is everything you need to know about shoe width sizing.
Understanding Shoe Width: What Does B Mean
The letter B in shoe size is for width measurement, not length. In women's shoes, B is medium or regular width - it's the comfort sweet spot that's neither too tight nor too loose. Consider it the "regular" width that the majority of women's feet comfortably fit.
For men's shoes, B refers to narrow width, whereas D is their regular medium width. This distinction comes as a surprise to new shoe buyers, but only when you realize that men's feet are usually broader than women's feet, does it seem logical.
What Does B Mean in Men's Shoe Sizes
If you're a male shopper buying shoes from our men's collection, a B width is narrow-fitting shoes. D is the men's medium width, as men's feet tend to be proportionally wider. Not every man will require the B width unless he has very narrow feet. If you have narrow feet and you're a man, B width shoes may fit far better than regular D width shoes.
Here's what men's width letters are:
- B: Men's narrow width
- D: Men's medium/standard width
- E: Men's wide width
- EE: Men's extra wide width
What Does B Represent in Women's Shoe Sizes?
For women browsing our women's shoe collection, the B width is your standard option. B refers to women's standard width shoes, meaning if you have standard-width feet, this is probably your ideal fit.
If you don't notice any width letters on a woman's shoe, you're typically viewing medium B-width shoes. Most shoe manufacturers do not always label the standard width, thinking it is the default.
Women's width breakdown:
- AA: Extra narrow width
- A: Narrow width
- B: Medium/standard width
- D: Wide width
- E: Extra wide width
What Does B Mean in Boot Size?
Boot sizing follows the same width rules as regular shoes. For women's boots, B means medium width, while for men's boots, B indicates narrow width.
However, boots can feel different than regular shoes even in the same width. This happens because boots cover more of your foot and ankle. When shopping for B width boots, consider:
- The boot height affects fit around your calf
- Thick socks might make B width feel tighter
- Boot leathers tend to stretch less than shoe leathers
- Ankle boots vs. knee-high boots fit differently
If you typically wear B width shoes, begin with B width boots but be prepared to go up a size if necessary.
Is B Standard Size for Women?
Yes, B width is definitely the standard size for women's footwear. The women's standard medium width is B, and shoe boxes and tags typically only name widths other than standard.
This implies whenever you look at women's shoes with no width designation, they're probably B width. A total of around 80% of women are well-fitted in B width shoes, so it's the most prevalent width produced.
If you've been purchasing shoes without considering width and they fit well overall, chances are you have B width feet.
How to Measure Your Foot Width at Home
Measuring your foot width ensures that you check whether B width is appropriate for you. Below is my easy technique that I suggest to all Ardur Shoes clients:
What you'll need:
- A piece of paper bigger than your foot
- A pencil or pen
- A ruler or measuring tape
Step-by-step process:
- Put the paper on a hard floor
- Position your foot on the paper with your heel leaning against a wall
- Trace around your whole foot with the pencil held upright straight
- Mark the widest areas on each side of your foot
- Measure between these widest areas
- Compare your measurement with a width chart
Take the measurement in the evening when your feet feel slightly swollen from daily wear. This provides you with the most accurate size for all-day comfort.
Width measurements for B width:
- Size 6: 3.3 inches
- Size 7: 3.4 inches
- Size 8: 3.5 inches
- Size 9: 3.6 inches
- Size 10: 3.7 inches
Gender Distinctions in B Width Sizing
The largest misunderstanding regarding B width is due to gender distinctions. D or DM typically refers to medium width for men, whereas B or BM refers to medium width for females.
Why there is a difference
The feet of females are usually smaller and narrower compared to men's feet. Shoe manufacturers developed various width standards to suit these natural differences. A woman's B width is approximately the same as a man's narrow width.
Cross-gender shopping
Occasionally women with broader feet shop in men's shoes for more width choices. If you are a woman considering men's shoes from our men's collection, you'd usually search for B width in men's sizes, which would be comparable to a D width in women's shoes.

Tips on Choosing the Right B Width Shoes
Having assisted thousands of shoppers to find their ideal fit, here are my best tips for selecting B width shoes:
Before you purchase:
- Measure both feet (one is likely to be slightly larger)
- Shop in the afternoon when feet tend to be swollen naturally
- Think about the socks you will wear with the shoes
- Check the reviews from others with similar foot shapes
Don't:
- Assuming all brands of shoes fit the same
- Buying tight-fitting shoes in hopes that they stretch
- Not considering your foot shape (high arches, flat feet, etc.)
- Styling over the proper fit
Indications B width is for you:
- No pinching of sides of feet
- Your foot doesn't overflow the shoe edges
- No space between your foot and shoe sides
- 30 minutes of comfortable wear
When B width may not fit:
- Your feet feel pinched on the sides
- You get calluses on the sides of your feet
- Shoes leave red blisters after being worn
- You find yourself needing to size up in length for width
Understanding Width Variations Between Brands
Not every B width shoe fits precisely alike. Various shoe companies have varying opinions regarding what B width is. This is referred to as "last variation" in the world of shoes.
Some companies run narrow on their B width, and others run wide. Therefore, it is critical to read customer reviews and learn about return policies when purchasing width-specific footwear.
At Ardur, we try on shoes of every brand we carry and give straightforward feedback regarding how each model fits relative to standard B width measurements.
Popular Misconceptions Regarding B Width Shoes
Let me dispel some popular myths I hear from consumers:
Myth 1: "B width shoes are more difficult to locate"
Reality: B width is actually the most prevalent width produced for women's footwear.
Myth 2: "All shoes stretch to fit your width"
Truth: Leather will stretch a bit, but you should never purchase shoes that are too narrow with the expectation they'll stretch enough.
Myth 3: "Width doesn't matter if the length fits"
Truth: Incorrect width will lead to blisters, calluses, foot pain, and other issues.
Myth 4: "Athletic shoes don't require specific widths"
Reality: Athletic shoes require appropriate width fit just like dress shoes, particularly for running or walking.
Signs You Need a Different Width
Sometimes B width isn't the ideal one, even if it's the norm. Here are signs you may need a different width:
You may need narrow (A width):
- B width shoes feel loose on the sides
- Your foot slides around inside the shoe
- You have to tie laces extremely tight for safety
- You develop blisters due to foot motion within the shoe
You may require wide (D width):
- B width shoes are too tight around your feet
- You sense pressure on the outside of your feet
- Your feet extend beyond the sides of the shoe sole
- You consistently have to size up in length for comfort
The Health Impact of Proper Width Fitting
Wearing the incorrect width shoe impacts more than comfort. Inadequate width fit can result in:
- Narrow shoe bunions
- Hammertoes due to tight toe boxes
- Plantar fasciitis from inadequate foot support
- Back pain due to changed walking habits
- Calluses and corns due to pressure points
Correct B width fitting accommodates your foot's natural form and enhances good foot mechanics.
How Materials Influence B Width Fit
Various materials react in different ways in B width shoes:
Leather shoes:
- Stretch slightly with wear
- Conform to your foot shape over time
- May feel snug initially but loosen up
Synthetic materials:
- Usually don't stretch much
- Maintain their shape longer
- Need to fit properly from day one
Canvas and fabric:
- Can stretch significantly
- May become loose over time
- Good for slightly wider B width feet
Athletic mesh:
- Stretches in specific directions

Seasonal Considerations for B Width Shoes
Your feet vary throughout the year, which influences how B width shoes fit:
Summer considerations:
- Feet swell more in warm weather
- B width may feel tighter
- Opt for breathable materials
