Sneaker Widths Explained: How to Choose D, 2E, and 4E
Most people know their shoe length but not their width. However, width is the reason why a sneaker of the correct size can still pinch – or why it might squeeze the ball of your foot even if there's space at the front.
This guide explains what D, 2E, and 4E mean, how to determine your width, and which brands are suitable for wide or narrow feet.
What width actually means
Width describes the circumference of the shoe in the ball area – that is, at the widest part of the foot, just behind the metatarsophalangeal joints. Two shoes in EU 43 can have the same length but completely different widths.
The US system uses letters. You'll find these specifications mainly with New Balance, Brooks, and Asics, less often with Nike and adidas.
Widths at a glance
| Code | Description | For whom |
|---|---|---|
| B | Narrow (Men) / Standard (Women) | Narrow foot |
| D | Standard (Men) | Average foot |
| 2E | Wide | Wide ball of foot, ball pain in D |
| 4E | Extra wide | Very wide foot, high instep |
| 6E | Extremely wide | Special cases, medical need |
Important: For women's models, B is the standard width, not D. A women's shoe in D is therefore already considered "wide".
Determining your width
- Stand barefoot or in thin socks, with your weight evenly distributed.
- Measure the circumference of your foot at its widest point with a tape measure – all the way around, not too tightly.
- Relate the value to the length: As a rough rule of thumb, a ball circumference of about 24 to 25 cm for a foot length of 27 cm is considered standard width. Significantly more indicates 2E.
More accurate than any formula is your everyday feeling: If you regularly buy a half to full size larger so that it doesn't pinch at the ball of your foot, you don't need more length, but more width.
The classic mistake: larger instead of wider
Going up a size only provides minimal space in the ball area but makes the shoe significantly longer. The consequences:
- The foot slides forward when rolling off, the heel lifts.
- The shoe's flex point is no longer above the metatarsophalangeal joint – deep creases form in the upper material.
- Blisters on the heel and faster wear.
If your length is correct 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 4E |
| Asics | Rather wide | Common in running models |
| Nike | Rather narrow | Rare, mostly standard only |
| adidas | Narrow | Practically none |
| Converse | Narrow and flat | None |
Within a brand, there are differences: Nike Air Max models are wider than Dunks, adidas Samba and Gazelle are cut particularly narrow.
What helps if there are no width options
- Choose material. Mesh, knit, and soft nubuck stretch, stiff smooth leather hardly does.
- Adjust lacing. Skipping the crossover lacing in the ball area and lacing parallel noticeably relieves pressure.
- Thinner insole. Especially helpful for high insteps to gain some volume.
- Change model. More honest than any trick: For very wide feet, some silhouettes are simply not the right choice.
Frequently asked questions
Is 2E the same as a half size larger?
No. 2E provides more circumference for the same length. A half size larger lengthens the shoe without significantly widening the ball area.
Why do most brands not specify width?
Because they work with a standard last per model. Multiple widths mean more molds, more storage, and more costs – which is especially worthwhile for running shoes.
Does a too-tight shoe stretch over time?
Slightly in width, especially with leather and textile. Not in length. If it hurts when you first try it on, it won't get better.
Does width also apply to women's models?
Yes, but with a different scale: B is standard there, D is already wide.
