Sneaker Sizing Guide: Nike vs Adidas vs Jordan
Ordering sneakers online only works if the size is right. Every brand fits a little different — here's how the big ones actually run, so you get it right the first time.
The quick answer
| Brand | How they run | Our advice |
|---|---|---|
| Nike (Air Force 1, Dunk) | True to size, slightly narrow | Order your normal size; go up half if wide feet |
| Nike running (Pegasus, etc.) | True to size | Order your normal size |
| Jordan 1 / Retro models | True to size, roomy toe box | Order your normal size |
| Adidas (Samba, Superstar) | Runs long and narrow | Consider half size down |
| Adidas Ultraboost | True to size, snug knit | Order your normal size; knit stretches |
| Converse Chuck 70 | Runs large | Go half size down |
| Vans Old Skool | True to size | Order your normal size |
| UGG boots | Sheepskin packs down | Order your normal size; snug at first is fine |
Measure your feet (takes 2 minutes)
- Stand on a piece of paper, trace both feet in the evening (feet swell during the day).
- Measure the longer foot heel to toe in inches or cm.
- Compare against the brand's size chart — not another brand's.
- Leave about a thumb's width (half inch) between your longest toe and the shoe's end.
Between sizes?
Go up, not down — especially in leather shoes that don't stretch much. For knit and mesh uppers you have more flexibility since the material gives. If one foot is bigger (very common), fit the bigger foot.
Kids' sizing note
Kids' feet grow fast — leave a full thumb's width of room, and check the fit every couple of months. For youth basketball shoes like Jordans, a snug heel with room in the toes is the sweet spot for support.
