Why are Adidas Campus 00s so tight inside, and what size should you choose?
The Adidas Campus 00s model from Adidas is inspired by the skate culture of the 2000s. This means the shoe has an iconic wide shape, thick laces, and an extremely padded (puffy) tongue. It's precisely because of this massive internal padding that many people encounter a problem – when they order their usual size, the shoe feels incredibly tight and presses on the top of their foot. If you're unsure about choosing sizes for other models too, check out our general sneaker sizing guide.
📐 Sizing chart: How to order Campus 00s according to your foot
| Foot Type | Size Recommendation | How the shoe fits |
| Narrow foot | True to Size (TTS) - Your regular size. | The shoe will be tighter around the instep initially, but the tongue padding will loosen slightly after a few days. |
| Normal foot | Go half size up. | Ideal choice. You'll get enough room for your toes, but the shoe won't slip off your heel. |
| Wider foot / Higher instep | Go half size up / one full size up. | The thick tongue takes up a lot of space in the shoe. Going half to one size up will ensure maximum comfort. |
