New Balance running shoes fit roomier and truer to size with multiple width choices, while Nike running shoes feel narrower and often run small. For length both brands start from foot measurement, but for width New Balance offers an explicit range and Nike mostly sells standard width. Width letters mark forefoot room from narrow to extra-wide. That difference decides toe comfort, arch pressure, and whether orthotics fit without sizing up in length.

How is length measured?
Nike explains in its unisex footwear size-fit charts that men's and women's US sizes map to measured foot length in centimeters. The same charts warn that the CM number printed on shoe boxes and labels is different from foot length.
Measure heel to longest toe and match that number to the chart to find US size. Check each product chart because lasts and models can shift the feel of the same nominal size.
How do width choices compare?
New Balance Australia directs shoppers in its women's printable size chart to measure both foot length and horizontal ball width of each foot. Shoppers then compare those two numbers with the size-and-width chart on each product page. New Balance uses D as men's standard width and B as women's standard width.
Men's 2E and women's D mean wide, while men's 4E and women's 2E mean extra-wide, according to Best Walking Feet. The range spans narrow 2A through standard, wide, extra-wide 4E and rare 6E on many models, which aids wide-foot and orthotic users. Nike sells most running shoes in standard width only. It offers Wide and Extra Wide versions selectively on franchises such as the Pegasus 41 and Pegasus 42, according to Nike.
What does the fit feel like?
Testing summarized by Ready Sleek in its New Balance versus Nike comparison finds New Balance fits roomier and truer to size with multiple widths. The same comparison finds Nike lasts feel narrower and often run small.
Wide-foot runners feel this gap most at the ball and toes. Narrow-foot runners may prefer Nike's closer wrap, while high-volume feet often need New Balance width rather than added length.
How do you pick the right pair?
Fit varies by individual model and last rather than brand alone, according to Ready Sleek. Brand-level length and width rules do not guarantee the same fit across all Nike or New Balance runners.
Measure both feet late in the day and fit the larger foot. Leave thumb-width room ahead of the longest toe without heel slip.
- Choose New Balance by both length and letter width on the product chart.
- Choose Nike Wide or Extra Wide when pressure hits the outer forefoot.
- Consider half a size up in Nike when between sizes or using orthotics, as Best Walking Feet advises.
