Air Jordan 11 fits true to size for most people — about half a size larger in number than your Air Force 1. The patent leather mudguard wraps the foot tightly out of the box and softens over the first 10–15 hours of wear. Based on 603 owner-reported pairs in the Feetlot database, the typical wearer takes the same number in AJ11 as in AJ1 or AJ3. If unsure: order true to size. Wide feet should size up half — the patent leather doesn't widen meaningfully.
Air Jordan 11 Sizing — What 603 Pairs in the Feetlot Database Tell Us
The Air Jordan 11 is among the most-tracked retro Jordans in the Feetlot database. Across 603 owner-reported pairs, the residual variance is tight (standard deviation ≈ 0.23 size units), meaning sizing is consistent across the AJ11 Low, Mid, and the classic 1995-era high-top — and across the various retro releases (Concord, Bred, Space Jam, Cool Grey, Legend Blue, 72-10). The "AJ11 fits true to size, runs slightly snug from the patent" pattern lines up with what Feetlot data actually shows: the typical wearer sits at their true Nike size — same number as where they wear AJ1 and AJ3.
The reason AJ11 runs at true Nike size — rather than half down like AF1 — is the patent leather mudguard combined with the ballistic mesh upper. The patent leather wraps the foot from the midfoot down to the toe and doesn't stretch like the softer leathers used on AF1 or AJ4. The ballistic mesh on the upper holds its shape and the carbon fiber spring plate keeps the midsole rigid. Going below true Nike size pinches the metatarsals against the unyielding patent.
Should You Size Up or Down in Air Jordan 11?
Standard fit (most people)
Order true to size — your usual Nike sneaker size, which is the same number you'd buy in AJ1 or AJ3. The patent leather feels snug on day one and softens over the first 10–15 hours of wear, but the length is set the moment you buy. True-to-size is what most Feetlot owners report as the correct fit.
Wide feet
Size up half. The patent leather mudguard resists stretching, and the wraparound construction means wide-footed wearers feel forefoot pressure at true size. Width isn't offered separately on most AJ11 colorways. Half a size up is the standard wide-foot adjustment in the Feetlot database.
Narrow feet
True to size still works for most narrow feet thanks to the snug patent wrap and ballistic mesh, which both pull the upper close to the foot. Going half down occasionally fits very narrow feet, but the carbon fiber spring plate in the midsole limits how much the foot can shift forward in a too-small pair.
AJ11 Low vs Mid vs (High) Retro
The AJ11 Low and AJ11 Mid use the same last and the same length as the classic high-top. Differences are at the collar — the Low cuts well below the ankle, the Mid sits at the ankle, and the High wraps above it. All three follow the same true-to-size advice in the Feetlot database. The patent leather mudguard is identical across Low/Mid/High, so the forefoot fit is the same.
How AJ11 Compares to Other Sneakers
The Air Jordan 11 fits at the same numerical size as Air Jordan 1, Air Jordan 3, Air Jordan 4, Nike Air Max 1, Air Max 90, Air Max 95, Air Max 97, Air Max 270, Nike Dunk Low, Nike Dunk High, SB Dunk Low, Nike Blazer Mid '77, Vans Authentic, Vans Old Skool, adidas Stan Smith, adidas Gazelle, adidas NMD R1, New Balance 574, 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 AJ11.
The shoes that run larger in number than AJ11: Nike Air Force 1, Converse Chuck Taylor (Low and Hi), and Sperry Authentic Original all run about half a size larger than AJ11 — so if you wear AJ11 in 10, you'd take 9.5 in those. Boot-style models (Red Wing Iron Ranger) run a full size smaller than AJ11 in number — size down a full size from AJ11 there.

Common Sizing Mistakes
- Buying AJ11 in your AF1 size. AF1 runs about half a size larger in number than AJ11. If your AF1 fits half down from true Nike, then your AJ11 should be true to your Nike size — not also half down.
- Sizing down half because "Jordans run big". True for some Jordans (AJ12 silhouettes) but not AJ11. The patent leather mudguard doesn't compress, and a half-down pair pinches the forefoot.
- Expecting the patent leather to stretch. The patent finish bonds to the leather and resists stretching. Don't size small expecting the mudguard to widen with wear — it won't.
- Treating AJ11 Low like a different last than AJ11 High. They use the same last and the same length advice. The only differences are the collar height and the laceup count — neither changes the size you'd buy.
- Confusing GS sizing. AJ11 GS (Grade School) tops out at 7Y. Men's starts at 7. A "size 7" can mean either — check the box. The GS versions have a less rigid midsole and feel marginally softer.
How Feetlot Computes These Numbers
Every Air Jordan 11 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 AJ11 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 AJ11 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.
