No, most Adidas run true to size in length, but several popular models are narrow and a few run small or long. We checked sizing data on 23 Adidas models to give you a clear answer.
Finding the right fit depends heavily on the specific silhouette you want to buy. Terrace classics feel tight because of their width, while certain running shoes actually run short. We break down exactly what to expect from every major model below.
Adidas size chart (US, UK, EU and cm)
| US Men | US Women | UK | EU | Foot length (cm) |
|---|---|---|---|---|
| 6 | 7 | 5.5 | 38 2/3 | 23.8 |
| 6.5 | 7.5 | 6 | 39 1/3 | 24.2 |
| 7 | 8 | 6.5 | 40 | 24.6 |
| 7.5 | 8.5 | 7 | 40 2/3 | 25.0 |
| 8 | 9 | 7.5 | 41 1/3 | 25.5 |
| 8.5 | 9.5 | 8 | 42 | 25.9 |

| 13 | 14 | 12.5 | 48 | 29.7 |
Understanding this chart helps you avoid ordering the wrong pair. Keep these three rules in mind when converting your size.
- On the Adidas chart, US women’s is one size above US men’s, meaning a men’s 8 equals a women’s 9.
- Adidas EU sizes use thirds, like 40, 40 2/3 and 41 1/3, so EU is the most precise way to order.
- Foot length is heel to longest toe and you should measure at the end of the day when your feet are slightly swollen.
Do Adidas run small? Model by model
We analyzed buyer reports and manufacturer specs to sort the most popular silhouettes into three distinct fit categories. Use these tables to find your exact match.
Adidas models that fit true to size
| Model | Fit | What to buy | Width |
|---|---|---|---|
| Ultraboost 5X | True to size | Your usual size | Stretchy knit, roomy toe box |
| Supernova Rise 2 | True to size | Usual size, or the Wide version | Regular and Wide |
| Runfalcon 5 | True to size | Usual size, or the Wide version | Wide version available |
| Duramo 10 | True to size | Your usual size | Average, wide available |
| Cloudfoam Pure 2.0 | True to size | Your usual size | Fixed tongue, snug entry |
| Taekwondo | True to size | Your usual size | Slim, low volume |
| Handball Spezial | True to size | Usual size, half up for wide feet | Narrow, suede stretches |
| Campus 00s | True to size | Usual size, half up for wide feet or high insteps | Standard D, thick padding |
| Gazelle | True to size | Usual size, half up for wide feet | Medium to narrow |
| Samba OG | True to size in length | Usual size, half up for wide feet | Very narrow toe box |
| SL 72 OG | True to size for most | Usual size, half up for wide feet | Narrow, low toe box |
| Ultraboost 1.0 | True to size | Usual size, half up for wide feet | Narrow to medium |
| Adistar 3 | True to size | Usual size, half up for wide feet | Slightly narrow forefoot |
| Solarglide 5 | True to size | Usual size, half up for wide feet | Medium |
| Terrex Free Hiker 2.0 | True to size | Usual size, half up for wide feet | Snug midfoot, roomy toe |
The Handball Spezial features unlined suede that stretches and molds to the foot over time. This natural give makes the initial snug fit much more comfortable after a few wears. The Samba OG toe box is about 66 mm wide near the big toe, making it one of the narrowest in our data. This tight squeeze can be a problem with bunions.
Adidas models that run small
| Model | Fit | What to buy | Width |
|---|---|---|---|
| Adizero SL2 | Snug and slightly short | Half up if between sizes or wide | Narrow, tapered toe |
| Galaxy 6 | Runs small | Half size up | Roomy forefoot |
| Pureboost 23 | Leans small | Half up if between sizes | Roomy toe box |
| Solarboost 5 | Leans small | Half up for wide feet or thick socks | Medium to slightly narrow |
The Adizero SL2 uses a race-inspired last with a pointed, tapered toe box that restricts toe splay. In our data, its internal length runs about 1.4 mm shorter than average. The Galaxy 6 runs small for many of its 1,100 buyer reports, so order half a size up. The forefoot is unusually wide at 107.2 mm, so the issue here is strictly length and not width.
Adidas models that run long or roomy
| Model | Fit | What to buy | Width |
|---|---|---|---|
| Stan Smith | True to size to slightly long | Usual size, half down for narrow feet | Medium, fairly wide toe box |
| Superstar | Slightly long | Usual size, half down for narrow feet | Medium to narrow, rounded toe |
| Gazelle Bold | Mixed, often roomy | Usual size or half down | Wider than the Samba |
| Racer TR23 | True to size, loose | Your usual size | Wide toe box and platform |
Adidas says the Stan Smith is true to size, but many buyers report it runs about half a size large. You might want to size down if you have narrow feet. Standard feet often find the Superstar slightly long, which can cause heel slip during longer walks. The toe on the Superstar is rounded and does not taper, giving you plenty of space in the front.
Why Adidas classics feel small: width, not length
The bigger issue with Adidas is width, not length. The terrace classics like the Samba OG, Gazelle, SL 72 OG, Handball Spezial and Taekwondo are built narrow. People with wide feet often go up half a size in these, even though the length is true to size.
Going up half a size for width adds length too, so the heel can slip. This creates a frustrating fit where your toes have room but your foot slides around. We suggest looking at a wide-friendly model instead when width matters, such as the best Adidas walking shoes for all-day comfort.

Adidas vs Nike sizing
If you already own a pair of Nikes, they make a good starting point. Most running models align perfectly across both brands. Lifestyle shoes need more attention because their shapes differ more.
- Against the Nike Pegasus, most Adidas running shoes like the Ultraboost 5X, Supernova Rise 2, Solarglide 5, Solarboost 5 and Adistar 3 take the exact same US size.
- The Nike Air Force 1 runs large, so many buyers who wear an Air Force 1 in a 10 take a 10.5 in Adidas running and lifestyle models.
- Against the Nike Dunk Low, the Samba OG, Taekwondo and Ultraboost 1.0 are often bought half a size up because they are narrower, while the Gazelle and Superstar are often bought half a size down because they are longer. Read our full Samba OG vs Dunk Low comparison for more details.

$60 retail · Amazon $45–$65
4.3/5 (1,100 user reports)
- Cloudfoam cushioning

How to choose your Adidas size
- Measure: trace your foot on a piece of paper and measure from the heel to the longest toe to find your exact centimeter length.
- Check the model table: always look up the specific silhouette you want to buy because fit varies wildly between running and lifestyle shoes.
- Wide feet: size up half a size in narrow terrace classics if you have a wide forefoot, but expect a bit of extra length in the toe.
- Between sizes: always round up to the next half size if your foot measurement falls exactly between two numbers on the official chart.
- Returns: buy from a seller with easy returns just in case the fit is wrong, and visit our Adidas Black Friday deals page for discounts.
Final verdict
Most Adidas shoes will fit your usual size right out of the box. You only need to adjust your size if you are buying a narrow terrace classic or one of the few running models that run short. Always rely on the specific model data rather than assuming the entire brand fits the same way.
