adidas NMD R1 Primeknit fits in the same number as Air Force 1, adidas Superstar, adidas Stan Smith, and Converse Chuck Taylor — and about half a size smaller in number than Air Jordan 1, Air Max 90, Nike Dunk Low, and adidas YEEZY Boost 350 V2. Based on 207 owner-reported pairs in the Feetlot database, the NMD R1 Primeknit (offset −0.081) fits slightly larger than the solid-mesh NMD R1, placing it in the AF1 cluster rather than the AJ1 cluster. If unsure: order true to size (same as AF1/Superstar). Coming from AJ1 or AM90: size down half.
NMD R1 Primeknit Sizing — What 207 Pairs in the Feetlot Database Tell Us
The adidas NMD R1 Primeknit is among the most-tracked NMD variants in the Feetlot database. Across 207 owner-reported pairs, the residual variance is tight (standard deviation ≈ 0.25 size units), consistent across all NMD R1 Primeknit colorways. At offset −0.081, NMD R1 Primeknit sits in the AF1/Superstar/Chuck cluster — about half a size below the AJ1/AM90/Dunk cluster. The key finding: the Primeknit upper construction runs slightly larger (more accommodating) than the solid-mesh NMD R1, which sits closer to the AJ1 cluster. Wearers transitioning between the two versions may notice a half-size difference.
The reason NMD R1 Primeknit fits slightly larger than mesh NMD R1 is the stretch properties of the Primeknit upper. Primeknit adapts to foot shape rather than holding a fixed volume, reducing the perception of length restriction — particularly in the toe box — and shifting the effective offset toward the AF1 zone.
Should You Size Up or Down in NMD R1 Primeknit?
Standard fit — coming from AF1, Superstar, or Chuck Taylor
Order true to size. AF1, Superstar, Stan Smith, Chuck Ox, and Chuck Hi all round to the same size as NMD R1 Primeknit in 0.5 increments. Same number in all of them.
Standard fit — coming from AJ1, AM90, Nike Dunk, or YEEZY 350 V2
Size down half. AJ1, AM90, Dunk Low, and YEEZY 350 V2 all run about half a size larger in number than NMD R1 Primeknit. If you wear AJ1 in 10, take NMD R1 Primeknit in 9.5.
Coming from solid-mesh NMD R1 (non-Primeknit)
Consider sizing down half. The mesh NMD R1 sits closer to the AJ1 cluster; the Primeknit version sits in the AF1 cluster — about half a size difference between the two constructions.
Wide feet
True to size. The Primeknit upper stretches to accommodate wider feet at the correct length.
Narrow feet
True to size. The stretch upper may feel slightly loose for very narrow feet — lacing snugly compensates.

Common Sizing Mistakes
- Using AJ1 or AM90 as the reference without adjusting. AJ1 and AM90 run about half a size larger in number than NMD R1 Primeknit. If you wear AJ1 in 10, take NMD R1 Primeknit in 9.5.
- Assuming NMD R1 Primeknit fits the same as mesh NMD R1. The Primeknit version sits in the AF1 cluster; the mesh version is closer to the AJ1 cluster. There may be a half-size difference between the two.
- Sizing up for the sock-like upper. The Primeknit upper stretches to fit, so true-to-size length is correct — sizing up leaves excess length.
How Feetlot Computes These Numbers
Every NMD R1 Primeknit 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). The result: sizing advice that holds up no matter how unusual a wardrobe is.
