Sneaker Widths Explained: Choosing D, 2E and 4E
Most people know their length, but not their width. Yet width is the reason a sneaker in the right size still pinches – or why it squeezes at the ball of the foot even though there's still room up front.
This guide explains what D, 2E, and 4E mean, how to determine your width, and which brands work for wide or narrow feet.
What width actually means
Width describes the shoe's circumference at the ball of the foot – the widest point, just behind the toe joints. Two shoes in EU 43 can have the same length and completely different widths.
The US system uses letters. You'll find these mostly on New Balance, Brooks, and Asics, less often on Nike and adidas.
Widths at a glance
| Code | Label | For whom |
|---|---|---|
| B | Narrow (men) / Standard (women) | Narrow foot |
| D | Standard (men) | Average foot |
| 2E | Wide | Wide ball of foot, discomfort in D |
| 4E | Extra wide | Very wide foot, high instep |
| 6E | Extremely wide | Special cases, medical needs |
Important: on women's models, B is the standard width, not D. A women's shoe in D there already counts as "wide".
Determining your width
- Stand barefoot or in thin socks, weight distributed evenly.
- Measure the circumference of your foot at its widest point with a tape measure – all the way around, not too tight.
- Set the value in relation to your length: as a rough rule of thumb, a ball circumference of about 24 to 25 cm at a foot length of 27 cm counts as standard width. Noticeably more suggests 2E.
More telling than any formula is everyday experience: if you regularly buy half to a full size up so it doesn't pinch at the ball of your foot, you don't need more length, you need more width.
The classic mistake: bigger instead of wider
A size up only gives minimal room at the ball of the foot, but makes the shoe noticeably longer. The consequences:
- Your foot slides forward while walking, and your heel lifts.
- The shoe's flex point no longer sits over your toe joints – deep creases form in the upper.
- Heel blisters and faster wear.
If your length is right and it's still tight, width is the problem.
Brands and lasts
| Brand | Last | Width options |
|---|---|---|
| New Balance | Wide, high toe box | Many models in D, 2E, some in 4E |
| Asics | Tends to be wide | Common on running models |
| Nike | Tends to be narrow | Rare, usually only standard |
| adidas | Narrow | Practically none |
| Converse | Narrow and flat | None |
There are differences within a brand too: Nike's Air Max models run wider than Dunks, and adidas Samba and Gazelle are cut especially narrow.
What helps when there's no width option
- Choose your material. Mesh, knit, and soft nubuck give a little, stiff smooth leather barely does.
- Adjust your lacing. Skipping the crossover at the ball of the foot and lacing parallel there noticeably relieves pressure.
- Thinner insole. Brings back some volume, especially with a high instep.
- Switch models. More honest than any trick: for a very wide foot, some silhouettes simply aren't the right choice.
Frequently asked questions
Is 2E the same as going half a size up?
No. 2E gives more circumference at the same length. Half a size up lengthens the shoe without meaningfully widening the ball area.
Why don't most brands specify width?
Because they work with one standard last per model. Multiple widths mean more molds, more inventory, and more cost – which pays off mainly for running shoes.
Does a shoe that's too tight stretch over time?
A bit in width, especially with leather and textile. Not in length. If it hurts on first try-on, it won't get better.
Does width apply to women's models too?
Yes, just on a different scale: B is standard there, D already counts as wide.
