Both are Adidas models, but lasts differ. Stan Smith is labeled True to Size (True to size; half up if wide). Superstar is Runs Big (Half down if narrow/average (shell-toe length); TTS if wide).
Adidas Stan Smith is one of the easier classics to size: most guides land on true to size for average feet. It sits narrower than Superstar, so wide feet may prefer half up rather than guessing from a Superstar size-down.
Superstar often feels long because of the rigid shell toe, so many narrow and average feet size down half to cut heel slip while the midfoot stays snug. Wide feet usually stay TTS for volume. Some brand-wide charts still label TTS — production and foot shape split the camps, so this stays Partial.
Use the table below as a starting point from fit offsets — then confirm with try-on or returns. Width can matter more than length between these two.
| Stan Smith | Superstar | |
|---|---|---|
| Verdict | True to Size | Runs Big |
| Advice | True to size; half up if wide | Half down if narrow/average (shell-toe length); TTS if wide |
| Width | Medium-narrow tennis last — snugger than Superstar forefoot | Shell toe adds dead length; forefoot can still feel snug |
| Break-in | Leather softens modestly | Shell toe does not stretch; leather upper softens |
| Fit offset | +0 | -0.5 |
| Confidence | high | medium |
