New Balance 574 fits true to size for most people — your usual Nike sneaker size, which is about half a size larger in number than your Air Force 1. Based on 819 owner-reported pairs in the Feetlot database, the typical wearer takes the same number in NB 574 as in Air Max 1, Air Max 90, or Air Jordan 4. If unsure: go true to size. Wide feet should consider 2E or 4E width before sizing up — New Balance is one of the few brands that offers them in nearly every length.
NB 574 Sizing — What 819 Pairs in the Feetlot Database Tell Us
The New Balance 574 is the most-tracked New Balance silhouette in the Feetlot database. Across 819 owner-reported pairs, the residual variance is tight (standard deviation ≈ 0.24 size units), meaning sizing is consistent across the standard 574, the 574 Core, the various premium "Made in USA / UK" 574s, and the women's 574. The "574 fits true to size" advice you'll find on the New Balance product page lines up with what Feetlot data actually shows: the typical wearer takes their usual Nike sneaker size — which is about half a size higher in number than where they wear AF1.
The reason NB 574 fits true to size — rather than half down like AF1 — is the SL-1 last and the ENCAP midsole. The last has moderate forefoot volume and the suede-plus-mesh upper sits close to the foot without holding it tight. There's less slack to take up by sizing down compared to AF1's roomy leather upper. The standard D width is closer to a Nike "regular" than to a traditionally narrow last, so sizing comparisons map cleanly to true Nike size.
Should You Size Up or Down in New Balance 574?
Standard fit (most people)
Order true to size — your usual Nike sneaker size. The suede-and-mesh upper holds the foot at true length, the ENCAP midsole compresses minimally, and the standard D width fits like a typical Nike. True-to-size is what most Feetlot owners report as the correct fit, regardless of which 574 sub-variant they bought.
Wide feet
Order the 2E (wide) or 4E (extra wide) instead of sizing up. New Balance is one of the few sneaker brands that stocks both 2E and 4E in nearly every length of the 574, and width is the right lever for wide feet — going up in length to compensate for width gives a sloppy heel. Stay true to size and step up the width letter.
Narrow feet
Order the B width if you can find it (it's mostly stocked on women's-labeled colorways). For men's-labeled D width pairs, true to size still works for most narrow feet thanks to the structured heel cup. Going half down is rarely necessary — the ENCAP midsole gives the foot some grip on the insole.
NB 574 Classic vs Made in USA / UK 990, 991, 992
The standard retro 574, the 574 Core, and the various "Wild Pack" / "Iridescent" / collab 574s all use the same SL-1 last and the same length advice. The Made-in-USA 990v series uses a different last and runs slightly snugger — same length numerically but a touch tighter at the midfoot. Sizing advice on this page applies to the 574 only.
How NB 574 Compares to Other Sneakers
The New Balance 574 fits at the same numerical size as most modern Nike and adidas lifestyle silhouettes — Air Max 1, Air Max 90, Air Max 95, Air Max 97, Air Max 270, Air Jordan 1, Air Jordan 3, Air Jordan 4, Blazer Mid '77, SB Dunk Low, Nike Dunk Low, Nike Dunk High, and YEEZY Boost 350 V2. According to Feetlot data, all of these round to the same size in 0.5 increments — same number you wear in NB 574.
The shoes that run larger in number than NB 574: Nike Air Force 1, Vans Authentic, Vans Old Skool, Converse Chuck Taylor (Low and Hi), adidas Stan Smith, adidas Superstar, adidas Gazelle, adidas NMD R1, and Sperry Authentic Original all run about half a size larger than NB 574 — so if you wear NB 574 in 10, you'd take 9.5 in those. Boot-style models (Red Wing Iron Ranger) run a full size smaller than NB 574 in number — size down a full size from NB 574 there.

Common Sizing Mistakes
- Buying 574 in your AF1 size. AF1 runs about half a size larger in number than NB 574. If your AF1 fits half down from true Nike, then your 574 should be true to your Nike size — not also half down.
- Sizing up for forefoot width. New Balance offers 2E and 4E in nearly every length of the 574 — order the width instead. Sizing up in standard D gives a too-long shoe that still pinches.
- Treating Made-in-USA 990/992 like the 574. They use a different last and run slightly snugger at the midfoot. Same numerical size, different fit feel — don't assume 574 sizing transfers without trying on.
- Sizing for thick athletic socks at try-on. The 574 is designed for medium athletic socks. Try them on with the socks you actually plan to wear, not bulky boot socks.
- Confusing GS sizing. NB 574 in big-kids' sizing (PS, GS) tops out at 7 — adult Men's also starts at 7. A "7" can mean either — check the construction.
How Feetlot Computes These Numbers
Every New Balance 574 sizing recommendation on Feetlot is the output of a global offset model fit to over 100,000 owner-reported shoe records. Each shoe gets a single number — its "size offset" — that captures how its sizing drifts relative to a 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 NB 574 size.
This works better than the pairwise approach you'll see on most sizing blogs because Feetlot uses the entire wardrobe graph. A YEEZY 350 owner contributes data about how YEEZY fits relative to AF1 owners (who often own both), which links back to NB 574 owners through any shared model. Even when two users share zero shoes directly, the chain of users in between transmits a consistent recommendation. The result: sizing advice that holds up no matter how unusual a wardrobe is.
