New Balance 880 Sizing: Run Big or Small?

New Balance 880 Sizing, What the Feetlot Database Tells Us

The New Balance 880 is a neutral cushioned daily running shoe, and across the Feetlot database its fit pattern is steady and predictable, no wild-card behavior. Based on 89 verified pairs, Feetlot data shows the 880 running a hair small compared with the reference Nike Air Force 1, which lands it right around true to size for most feet. The widely repeated "New Balance runs true to size" advice matches what Feetlot data actually shows, with the standard running-shoe caveat that long-distance runners often want a touch more room up front.

Should You Size Up or Down in New Balance 880?

Standard fit (most people)

Order true to size. Feetlot data places the 880 a fraction smaller than the Air Force 1, so a true-to-size purchase gives a snug, locked-in midfoot with the engineered mesh upper hugging the foot. For walking, gym use, and shorter runs, that is the fit most wearers settle on.

Long-run and distance fit

Consider a half size up. Feet swell over the miles, and many runners take a half size up in the 880 specifically for toe-box room on long efforts, the same advice that applies to most daily trainers. If the shoe is mainly for distance, the half-up keeps toes from hitting the front on downhills.

Wide feet

Change the width, not the length. New Balance is one of the few brands that offers the 880 in multiple widths, D (standard), 2E (wide), and 4E (extra wide). Going up a width opens the forefoot and midfoot without stretching the length, so the shoe still locks the heel. This is a cleaner fix than sizing up, which only adds length and leaves the foot sliding.

Narrow feet

Again, change the width. The 880 comes in B (narrow) and 2A (extra narrow) for many sizes. A narrower width snugs the midfoot and heel so true-to-size length holds the foot in place, instead of dropping to a smaller number and cramping the toes.

How New Balance 880 Compares to Other Shoes

According to Feetlot data, the 880 fits almost identically to the Brooks Ghost, take the same size in both, as you would expect from two neutral daily trainers built on similar lasts. It runs a little smaller than casual lifestyle shoes such as the Vans Authentic and the Converse Jack Purcell, so wearers tend to take a slightly larger number in the 880 than in those flat sneakers.

The gap is widest against the Clarks Desert Boot: the 880 runs noticeably smaller, so owners who have both in the Feetlot database tend to take close to a full size larger in the 880 than in the Clarks. In the other direction, the 880 runs a bit larger than the PUMA Roma Basic, so a smaller number works there. Use these directionally, the cleanest path is still to match the width to your foot rather than chase length.

Common Sizing Mistakes

• Sizing up to fix a wide foot. The 880 comes in 2E and 4E widths, widen the shoe instead of lengthening it, or the heel will slip.
• Sizing down to fix a narrow foot. Drop to a B or 2A width rather than a smaller length, which cramps the toes.
• Assuming all running shoes match. The 880 fits like the Brooks Ghost but runs smaller than casual shoes like Vans, don't copy a flat-sneaker size straight across.
• Forgetting long-run swell. True to size is right for daily wear; distance runners often want a half size up for toe room.

How Feetlot Computes These Numbers

Every New Balance 880 sizing recommendation on Feetlot is the output of a global offset model fit to over 100,000 verified shoe records. Each shoe gets a single number, its "size offset", that captures how much its sizing drifts from the reference shoe (the Nike Air Force 1). When a Feetlot user provides their size in any tracked shoe, the model recovers their true foot baseline and recommends the matching New Balance 880 size. This works better than a simple pairwise lookup because Feetlot uses the entire wardrobe graph: even when two users share no shoes directly, the chain of users between them transmits a consistent recommendation. That is why a shoe with a modest number of direct owners still gets a stable size estimate.
