Converse Shoe Size Guide

Converse All Stars typically run large — most people size down half a size. Use the chart below.

Why Converse Sizing Trips People Up

The Converse Chuck Taylor All Star has barely changed in construction since 1917, and that's exactly why it's one of the more inconsistently-fitting sneakers people buy online. It's a canvas shoe built on a simple, relatively flat last with no width options, so the fit depends heavily on the specific style and how much wear it's had.

Why the classic Chuck Taylor runs big

The original Chuck Taylor All Star uses a roomier, older-pattern last than most modern sneakers, which is why it's consistently rated as running a full size to a size and a half large. Canvas also stretches as it's worn in, so a shoe that feels snug on day one will loosen further over the following weeks — which is why most seasoned buyers deliberately size down rather than buying true to size.

The Chuck 70 fits differently

Converse's Chuck 70 reissue line is built on a different, more structured last than the everyday Chuck Taylor All Star, with a thicker outsole and more supportive footbed. It runs noticeably closer to true size than the classic version, so if you're used to sizing down on regular Chucks, don't apply the same adjustment to the Chuck 70 without checking first.

No width options, narrow heel

Converse doesn't offer wide or narrow width variants on its core lines. The heel cup in particular is cut narrow, so people with wider feet often find the toe box fine but the heel loose or slipping — a thicker sock or heel-lock lacing pattern usually solves it better than sizing up.

Platform and leather styles

Platform Chuck Taylors and leather versions fit slightly differently again — the added sole height on platforms doesn't change length sizing, but leather uppers don't stretch the way canvas does, so they hold closer to their as-bought size through the shoe's life.

Sneaker Brand Size Guide

Not all sneakers fit the same. Here's how the major brands run relative to your true size — so you know before you buy. We've noted which specific models are affected and how much to adjust.

Brand Fit Adjustment Notes
Nike True to Size None needed Generally TTS across most styles. Air Force 1 fits slightly roomy. React and Pegasus running shoes can run narrow — wide-footer types should consider half a size up.
Adidas Runs Small Go ½ size up Ultraboost and NMD run about half a size small. Stan Smith and Gazelle are TTS but fit narrow — if you have wider feet, go half a size up. Yeezy sizing varies by model.
New Balance True to Size None needed TTS with excellent width options (B through 4E). Known for a comfortable, slightly roomier toe box than Nike. 990, 574 and 550 are all reliably TTS.
Jordan True to Size None needed Most Jordan models are TTS. Air Jordan 1 fits wide and roomy — narrow-foot types can size down half. Jordan 11 runs a touch large; some people prefer half a size down.
Vans Runs Large Go ½ size down Old Skool and Sk8-Hi run slightly long — go half a size down if between sizes. Canvas styles stretch a little with wear. Slip-ons tend to feel roomy, so size down more confidently.
Converse Runs Very Large Go 1–1.5 sizes down Chuck Taylors are famous for running big. Men should go 1 to 1.5 sizes down. Women should go down 2 full sizes (they use unisex sizing). The roomy toe box gets roomier as the canvas breaks in.
Puma True to Size None needed Suede Classic and RS models are reliably TTS. Puma fits slightly narrow across most styles — wider feet may prefer to go half a size up for comfort on longer wear days.
Reebok True to Size None needed Classic Leather and Club C are TTS. Reebok generally fits well across widths. Instapump Fury runs slightly narrow. Classics tend to have a slightly roomier toe box than running styles.

Fit notes reflect general fit across popular models and community feedback. Individual styles may vary. Always check the specific product page for fit recommendations before purchasing.

Sneaker Sizing — Frequently Asked Questions

How do I convert US shoe sizes to EU? +
To convert US men's sizes to EU, add roughly 33 to your US size — so a US 10 is approximately EU 44. For women, add about 31 to your US size, so a US 8 is around EU 38.5. The easiest approach is to use the converter above, which gives you the exact EU equivalent for your size instantly.
What is my shoe size in CM? +
Your shoe size in CM refers to the length of your foot in centimetres. You can measure it by standing on a piece of paper, tracing around your foot and measuring from heel to the tip of your longest toe. A US men's 10 is approximately 28cm, and a US women's 8 is approximately 25cm. Use the foot length helper in the converter above for an instant size recommendation.
Do Nike shoes run true to size? +
Nike shoes generally run true to size, but fit can vary by model. Running shoes like the Pegasus and React Infinity tend to be accurate to your normal size, while lifestyle styles like the Air Force 1 can feel slightly roomy. If you're between sizes in Nike, most people are comfortable going half a size down.
What is the difference between men's and women's shoe sizing? +
Men's and women's shoe sizes use different numbering systems even though they can refer to the same foot lengths. A women's US 8 is roughly equivalent to a men's US 6.5 — women's sizes run about 1.5 sizes larger than men's for the same foot. Women's shoes are also typically made on a narrower last, which matters when buying unisex or crossover styles.
How do I convert kids' shoe sizes to adult sizes? +
Big kids' sizes (Y) run up to a US 7Y, which is close to a US 7 in women's or a US 5.5 in men's. Kids' sizes and adult women's sizes overlap closely — a kids' 5Y is roughly a women's US 6.5. If you have wide feet, adult sizing is usually a better option since it comes in more width choices than kids' shoes.
What shoe size is EU 42 in US? +
EU 42 is a US men's 8.5 or a US women's 11, depending on the gender sizing chart you're using. EU sizes use the same number across men's and women's but the equivalent US size differs between the two. Use the converter above to check both conversions instantly.
Do Converse run big or small? +
Converse sneakers are well known for running big — most people go 1 to 1.5 sizes down from their usual size. The classic Chuck Taylor has a roomy toe box and uses unisex sizing, so women typically need to go down 2 full sizes compared to their normal women's size. If you're a US men's 10 in most brands, start with a Converse 9.

Frequently Asked Questions

Do Converse shoes run big?

Yes — the classic Chuck Taylor All Star is well known for running a full size to a size and a half large. Most buyers size down rather than buying their usual size.

What is Converse US 8 in EU?

Converse US Men's 8 converts to EU 41. Because Converse uses unisex sizing on most Chuck Taylor styles, that same EU 41 corresponds to a US Women's 10.

Are Converse men's and women's sizes different?

Converse uses one unisex size scale for its classic Chuck Taylor line, with women's sizes running about 1.5 to 2 full sizes larger in number than the equivalent men's size. Check the specific listing, since some newer Converse styles do use separate gendered sizing.

Do Converse fit wide feet?

Classic Converse have a standard width with a notably narrow heel cup, so wide feet often find the toe box fine but the heel loose. Sizing up doesn't usually fix a narrow heel — a thicker sock or different lacing pattern tends to work better.

Does the Chuck 70 fit the same as the classic Chuck Taylor?

No — the Chuck 70 reissue is built on a more structured, true-to-size last with a thicker sole, unlike the classic All Star's roomier fit. Don't apply the usual size-down rule from the classic Chuck Taylor to the Chuck 70 without checking first.

Do Converse stretch with wear?

Canvas Chuck Taylors do stretch and loosen noticeably over the first few weeks, which is part of why they're recommended to buy on the snugger side. Leather Converse styles hold their shape much more and don't loosen the same way.
