Nike Roshe Run fits true to size for most people — meaning your "true Nike size," not your AF1 size. Based on 410 owner-reported pairs in the Feetlot database, the typical wearer takes about half a size larger in number for Roshe Run than they do for Air Force 1. The engineered mesh upper and lightweight Phylon midsole follow the foot closely. If unsure: go true to size, or half a size up from your AF1 number. Wide feet should size up half.
Roshe Run Sizing — What 410 Pairs in the Feetlot Database Tell Us
The Nike Roshe Run is one of the most-tracked lifestyle silhouettes in the Feetlot database. Across 410 owner-reported pairs — spanning the original Roshe Run, the renamed Roshe One, and the chunkier Roshe Two — the residual variance is tight (standard deviation ≈ 0.22 size units), meaning sizing is consistent across the line. The typical wearer sits about half a size higher in number than they would in AF1, which puts Roshe Run right at the wearer's true Nike sneaker size.
The reason Roshe Run runs at true Nike size — rather than half down like AF1 — is the engineered mesh upper and the simple Phylon midsole. Dylan Raasch designed the shoe in 2012 as "a moment of Zen" — a stripped-down silhouette with no Air bag, no overlays, and a single-piece knit-like upper that wraps the foot directly. There's almost no internal space to take up by sizing down, and going below true Nike pinches the toes.
Should You Size Up or Down in Roshe Run?
Standard fit (most people)
Order true to size — your true Nike sneaker size. Don't carry your "half down from AF1" adjustment into Roshe Run; the close-fitting mesh upper takes up the slack that AF1 leaves loose around the midfoot. True-to-size is what most Feetlot owners report as the correct fit.
Wide feet
Size up half. The engineered mesh stretches a little around the foot over the first few wears, but it doesn't add meaningful width — the toe box stays moderate and the midfoot is intentionally snug. Half a size up adds forefoot room without making the heel slip, since the padded heel collar and pull-tab still lock the foot in place.
Narrow feet
True to size works for most narrow feet — the mesh upper conforms inward and the lace closure pulls the panels tight. Going half down occasionally fits very narrow feet, but the mesh presses against the toes when sized below true Nike. Try true to size first.
Roshe Run vs Roshe One vs Roshe Two vs Tanjun
The original Roshe Run, the rebranded Roshe One, the chunkier Roshe Two, and the budget Roshe LD all use the same last and the same length advice — true to size from your Nike sneaker baseline. The Tanjun, Nike's lifestyle successor to the Roshe Run, was built on essentially the same last and sizes the same; if you wear Roshe Run in 10, take Tanjun in 10. The Roshe Two has a chunkier triple-density midsole but the upper opening and length match the original.
How Roshe Run Compares to Other Sneakers
The Roshe Run sits within a quarter size of most modern Nike silhouettes — Air Max 1, Air Max 90, Air Max 95, Air Max 97, Air Jordan 1, Air Jordan 4, Blazer Mid '77, SB Dunk Low, Nike Dunk Low, Vans Authentic, adidas Superstar, and YEEZY Boost 350 V2 all round to the same size in 0.5 increments. So if you wear Roshe Run in 10, take 10 in any of those.
The shoes that run larger in number than Roshe Run: Nike Air Force 1, Converse Chuck Taylor (Low and Hi), Sperry Authentic Original, and Clarks Desert Boot. According to Feetlot data, these all run about half a size larger than Roshe Run — wear Roshe Run in 10, take 9.5 in those. Boot-style models like Red Wing Iron Ranger run a full size smaller in number — size down a full size.

Common Sizing Mistakes
- Buying Roshe Run in your AF1 size. AF1 runs about half a size larger than Roshe Run in number. If your AF1 fits half down from true Nike, then your Roshe Run should be true to your Nike size — not also half down.
- Sizing down because "Nike runs large". True for AF1 and a few other lifestyle silhouettes, not true for Roshe Run. The close-fitting mesh upper and Phylon midsole hold the foot tightly — going below true Nike pinches the toes.
- Treating Roshe Run like a sock-fit running shoe. The upper is engineered mesh, not the bootie construction of the Huarache or Free RN. It's less restrictive than a true sock-fit, so the "size down for sock fit" advice doesn't apply.
- Confusing GS with Men's. Roshe Run GS tops out at 7Y. Men's starts at 7. A "size 7" can mean either — check the box, the GS price tag is typically lower for a reason.
- Expecting the mesh to stretch a lot. The engineered mesh upper relaxes a little around the foot — enough to soften pressure points but not enough to fix a half-size-too-small purchase. Don't size small expecting break-in to rescue the fit.
How Feetlot Computes These Numbers
Every Roshe Run 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 Roshe Run 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 Roshe Run 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.
