Brand sizing differences
Nike uses its own fit models and lasts; sizes often differ from generic conversion charts. Shoes may run small or large depending on the line.
EU vs US discrepancies
EU and US sizing don't align 1:1. Nike products sold in Europe may be labeled in EU sizes; when buying from the US site you'll see US sizes. Use our converters below to translate between regions.
Fit type (narrow / wide)
Nike shoes often run narrow and slightly short; many buyers go half a size up. Width options exist for some running models.
Fit Characteristics
Some users report that this brand may feel narrower in the forefoot compared to standard sizing. If you experience tightness on the sides despite correct length, consider checking if wide versions are available. Fit can vary by model.
Real-world fit tips
Measure yourself and compare to Nike's official size chart for the specific item. When between sizes, many buyers size up for comfort. Read recent customer reviews for fit notes.
