New Balance vs ASICS vs Nike: 7 Key Differences

4. Fit and sizing philosophy

Fit differences are among the easiest to notice when you try shoes on. ASICS’ testing notes for the Novablast 5 showed slightly wider forefoot and heel dimensions in lab measurements, and reviewers often praise ASICS for accommodating wider feet in certain lines. RunRepeat’s measurements indicated extra forefoot/heel width on that model, which translates to a more secure and less pinching fit for many runners. Nike historically designs with neutral to narrower lasts in several of its performance models, though that varies by line and year. Nike does offer some wide-flag models, and many runners know to size up or try different widths. New Balance maintains a strong reputation for offering multiple width options across many models, including popular wide and extra-wide fittings, making it a reliable option for shoppers who need more room. Because fit varies by last and model, the safest route is to try the exact model and size or buy from retailers with easy returns. Pay attention to toe-box volume, heel lock, and how the shoe feels after a short jog; these factors are stronger predictors of comfort than brand alone.
