Why are Adidas Campus 00s so tight inside, and what size should you choose?
The Adidas Campus 00s by Adidas are inspired by the skate culture of the 2000s. That means the shoe has an iconic wide shape, thick laces, and an extremely padded (puffy) tongue. This bulky interior padding is exactly why many people run into a problem—their usual size feels incredibly tight and presses on the instep when they order it. If you’re unsure about sizing in other models too, check out our general sneaker size guide.
📐 Sizing chart: How to order Campus 00s for your feet
| Foot type | Size recommendation | How the shoe fits |
| Narrow feet | True to Size (TTS) - Your usual size. | The shoe will initially feel tighter around the instep, but the tongue padding will loosen slightly after a few days. |
| Regular-width feet | Go half size up (Half a size larger). | The ideal choice. You’ll have enough room for your toes, but the shoe won’t slip off your heel. |
| Wider feet / Higher instep | Go half size up / a full size up. | The thick tongue takes up a lot of space inside the shoe. Going up half to a full size will ensure maximum comfort. |
