You’ve found the perfect pair of boots online, but when you go to select your size, you’re hit with a confusing alphabet soup of options: D, E, EE, G, H. What do they mean? Is an “EE” the same as an “H”? Choosing the wrong one can lead to a painful fit, but the labels themselves are rarely explained.
Consider this your official decoder ring. In this guide, we’ll break down the difference between the two most common “extra wide” fittings—EE and H—and explain why they are not interchangeable. Understanding this simple difference is the key to unlocking a perfect, comfortable fit for your wide feet.
Decoding the US System: What Does EE Mean in Boots?

difference between ee and h
The “E” system is the standard for North American (US) brands. It’s a progressive scale where more letters generally mean a wider shoe. For most boots you buy in the United States, this is the system you’ll encounter.
- D is the Standard: For men’s footwear, a ‘D’ width is considered medium or standard. For women, it’s ‘B’.
- E is Wide: One step up from the standard.
- EE (or 2E) is Extra Wide: This is the most common “extra wide” designation. It offers a significant increase in width across the ball of the foot compared to a D width.
- EEE (3E), 4E, etc.: These indicate even wider fits, often used for therapeutic footwear or for those with specific foot conditions.
Quick Guide to US Widths
| Width Name | Men’s Letter | Women’s Letter |
|---|---|---|
| Medium / Standard | D | B |
| Wide | E | D |
| Extra Wide | EE (2E) | EE (2E) |
| Triple Wide | EEE (3E) | 4E |
Decoding the UK/EU System: What is an H Width Shoe?
The “H” width is part of a different sizing system, most commonly used by brands from the United Kingdom and Europe (like Germany and Austria). It also represents a wide fit, but its scale is different.
- F is the Standard: ‘F’ is considered the standard or medium fit.
- G is Wide: A step wider than the standard F.
- H is Extra Wide: This fitting provides extra width, but it also often incorporates more overall volume and depth in the shoe. This makes it an excellent choice for people with not just wide forefeet, but also high insteps.
- J and K: These letters represent even wider and more voluminous fits.
The Crucial Point: Are EE and H the Same?

No, they are not directly interchangeable. While both EE and H generally mean “extra wide,” they belong to different measurement systems and can have different implications for fit. An American size 10 EE boot will not fit exactly the same as a European size 44 H boot.
EE vs. H: The Key Differences
| Feature | EE (US System) | H (UK/EU System) |
|---|---|---|
| Region | North America | United Kingdom & Europe |
| Meaning | Extra Wide | Extra Wide |
| Key Characteristic | Primarily adds width across the forefoot. | Adds width and often extra depth/volume for the entire foot. |
| Best For | People with a wide, flat forefoot. | People with a wide forefoot and a high instep. |
The bottom line is that the “last”—the foot-shaped model a boot is built on—has more impact on the final fit than the letter on the box. A sleek, narrow last will feel tight even in an EE, while a boot on a naturally voluminous last might feel roomy even in a D.
The 3-Step Rule for Choosing the Right Width
- Measure Your Foot: Don’t guess your width. Use a Brannock device at a shoe store or measure your foot at home to get an accurate measurement in inches or centimeters.
- Know the Brand’s Origin: Are you buying from an American brand like Red Wing or Thorogood? You’ll be using the EE system. Looking at a German brand like Haix or Lowa? You’ll likely see the H system.
- Always, Always Check the Brand’s Chart: This is the most important step. Visit the manufacturer’s official website and find their specific sizing and width chart. This is the only way to accurately convert your foot measurement to their specific sizing scale.
Final Verdict: Think of Them as Cousins, Not Twins
Think of EE and H as serving the same purpose—providing a comfortable fit for wider feet—but speaking slightly different languages. They are analogous, but not equal. By understanding which system you’re dealing with and always referring back to the brand’s official size chart, you can finally put an end to the sizing guesswork and find a boot that fits perfectly.
