From factory last-shape testing and OEM sampling:
Most NB everyday and running models match standard US sizing.

| Nike | Slightly small / narrow | Slim silhouettes, less width variety |
| Adidas | True to size | Softer toe box in lifestyle models |
Takeaway:
NB = best for stability + width options.
Nike = slim.
Adidas = more forgiving.
| Model | Fit | Notes |
|---|---|---|
| NB 990 / 993 / 2002R | True to size | Comfortable, classic fit |
| Fresh Foam Series | True to size | Soft cushioning, everyday running |
| FuelCell Series | Slightly small | Performance-focused, snug toe |
| Minimus / Training | Slightly small | Designed for gym stability |
OEM Insight:
Performance midsoles often shape the interior differently, causing a snugger feel.
