Comparison
Adidas vs Puma Fit
Adidas and Puma share a European sportswear pedigree and a narrow-last philosophy, but they part ways at the sizing label — Adidas runs half a size long across the board, Puma sits true.
Adidas: 0.5 long on Ultraboost, Samba, Gazelle, Stan Smith. Terrex trail and Adizero racing are exceptions — true to size.
Puma: true to size on Suede, Palermo, Speedcat, RS-X. Racing (Deviate NITRO, Fast-R) is true but snug through the forefoot.
Both narrow through the midfoot. Wide-footed runners should move to New Balance, ASICS or Brooks.
| Silhouette equivalent | Adidas | Puma | Fit |
|---|---|---|---|
| Retro low | Samba | Palermo | Adidas 0.5 long; Puma TTS |
| Retro mid | Gazelle | Suede | Adidas 0.5 long; Puma TTS |
| Cushion runner | Ultraboost | Deviate NITRO | Adidas 0.5 long; Puma TTS |
| Race | Adizero Pro | Fast-R | Both TTS, both snug |
Key takeaways
- Adidas: size down 0.5. Puma: true to size.
- Both narrow midfoot — not ideal for wide feet.
- Same US 9 in Adidas and Puma = different fit; the label lies half a size.
