Finding the right shoe size can be tricky, especially when buying from iconic brands like Nike and Converse. These brands offer a wide range of styles, yet their sizing can vary.
For example, Nike’s Air Force 1s typically have a roomier fit, while their running shoes tend to feel more snug. Similarly, Converse shoes can differ based on the model you choose—just a minefield when buying trainers online.
To help you find the best fit every time, we’ve put together a comprehensive guide on Nike vs Converse shoe sizing, width options, and more.
How Should Your Nike and Converse Shoes Fit?
Before diving into the size charts, it’s important to know how your shoes should fit to ensure comfort (according to Clarks):
- Length: A general rule is to leave one finger's width of space between your longest toe and the end of the shoe. This gives your feet room to move comfortably without being too tight.
- Width: The widest part of your foot, which includes the ball of your foot, should align with the widest part of the shoe to avoid discomfort. Shoes that are too wide can cause your feet to slide, while shoes that are too narrow may compress your feet.
Nike vs Converse: Shoe Size Comparison
When it comes to sizing, Nike and Converse shoes are quite similar in length.
For instance, a Men’s US 9 from Nike is only slightly smaller than a Men’s US 9 from Converse. This is likely because Nike owns Converse, which may explain the similarity.
However, keep in mind that shoe sizes can still differ depending on the model. Even within the same brand, the fit may vary, particularly between high-performance sports footwear and more casual everyday sneakers such as Nike Dunks.

Width Comparison
Nike offers a width chart to help you find the right fit for your foot’s width. For example, a Men's US size 10 is suitable for feet measuring about 4.2 inches in width.
In contrast, Converse doesn’t provide a width chart, but they do offer a variety of options to accommodate different foot shapes. Converse shoes are generally more straightforward in terms of sizing, but still feature some variations in width.

Fortunately, more general information can be found online regarding shoe width. Here is a breakdown of width codes for a Men's US 8 shoe:
- B - Approx. 8.73cm
- D - Approx. 9.68cm
- 2E - Approx. 10.64cm
- 4E - Approx. 11.59cm
Note that width varies depending on the shoe length. For example, a US size 6 will have a different width than a US size 12.
Best Nike and Converse Shoes for Wide Feet
If you have wider feet, both Nike and Converse offer wide-fit shoes designed for comfort:
- Nike provides wide versions of popular models like the Pegasus 41, and they recommend wide fits for feet measuring 3.9 inches or more in width.
- Converse offers wide-fit options such as the Chuck Taylor All Stars with added volume (about 15mm more at the ball and 6mm at the bottom) for extra comfort.
Both brands offer a great selection of wide shoes to ensure your feet feel supported without any discomfort.
Which Nike and Converse Shoes Run Narrow?
If you’re looking for shoes with a narrower fit, consider these options:
- Nike’s Free range typically features a snug fit with an internal webbing system that provides a locked-in feel, perfect for athletic activities.
- Nike Flyknit models are known for their close fit, thanks to their breathable knitted mesh that conforms to the natural shape of your foot.
- Converse Chuck Taylor All Stars also tend to run narrower due to their sleek canvas design, although wide options are available.
If you have narrow feet, these models may offer the best fit for you.
Frequently Asked Questions (FAQs)
Got questions about Nike and Converse sizing or fit? Here are some quick answers to the most frequently asked questions to help you shop with confidence.
Do you need to break in Nike and Converse shoes?
Yes, both Nike and Converse shoes usually need a short break-in period, though it depends on the model and materials.
Nike athletic shoes are often designed for comfort right out of the box, but leather styles like Air Force 1s may feel stiff and take a few days to soften. Converse Chuck Taylor All Stars, with their canvas uppers and rubber soles, can feel rigid at first, too, especially around the toe and heel, but typically loosen up after a few wears.
To make the process easier, wear them indoors for short periods and use cushioned socks to minimize friction.
Is it better to try Nike and Converse shoes on in-store or order online?
Trying on in-store is best if you’re unsure about sizing, but online ordering is convenient thanks to solid size guides and return policies.
In-store fitting lets you check for comfort, width, and arch support, which is especially helpful if you have wide or narrow feet. Online shopping is still a safe bet, though, as both Nike and Converse offer detailed sizing charts and easy returns.
If you’ve worn one brand before, you can likely order online with confidence, but first-time buyers or those between sizes may benefit from testing them in person.
Final Thoughts
Getting the right fit is essential for comfort and performance. So, be sure to check the width and length measurements, and consider trying on different styles to find what works best for your foot shape.
