Nike Air Max Plus (TN) fits true to size for most people — the same number as Air Jordan 1, Air Max 90, Air Max 97, and YEEZY Boost 350 V2, and about half a size larger in number than Air Force 1 or Vans Authentic. The mesh-and-leather upper with external heel straps holds the foot closely. Based on 338 owner-reported pairs in the Feetlot database, the typical wearer takes the same number in AM Plus as in AJ1 or AM97. If unsure: order true to size. Wide feet should size up half — the structured toe cap doesn't widen with wear.
Air Max Plus Sizing — What 338 Pairs in the Feetlot Database Tell Us
The Nike Air Max Plus is the most-tracked TN Air sneaker in the Feetlot database. Across 338 owner-reported pairs, the residual variance is tight (standard deviation ≈ 0.25 size units), consistent across the various AM Plus colorways (Black, Hyper Blue, University Red) and the various "TN" retro releases. Feetlot data shows AM Plus fits in the same bucket as Air Jordan 1, Air Max 90, Air Max 97, and YEEZY 350 V2 — true to size — and about half a size larger in number than Air Force 1 or Vans Authentic.
The reason Air Max Plus runs at true Nike size — and half a size above AF1 — is the structured upper with external heel straps. The mesh-and-leather construction wraps the foot more closely than AF1's padded leather, and the straps anchor the heel at length. The tuned Air unit sits in the heel without adding length slack. Going below true size presses the toes against the toe cap.
Should You Size Up or Down in Air Max Plus?
Standard fit (most people)
Order true to size — your usual sneaker number, same as AJ1, AM90, AM97, or YEEZY 350 V2. If you normally size AF1 half down from your Nike baseline, take AM Plus at your Nike baseline. If you own AJ1 in size 10, take AM Plus in size 10.
Wide feet
Size up half. The structured toe cap and external heel straps hold the shape rigidly. Width isn't offered separately on most AM Plus colorways. Half a size up is the standard wide-foot adjustment.
Narrow feet
True to size works for most narrow feet — the straps and lacing system hold the foot without requiring extra width. Going half down risks the toe cap pressing the metatarsals.
Air Max Plus vs Air Max Plus III
The original Air Max Plus (TN, 1998) and the Air Max Plus III use the same last and the same length advice — true to size. The Plus III adds a full-foot Tuned Air unit compared to the heel-only unit in the original, but the upper last is unchanged. Same size across all AM Plus generations.
How Air Max Plus Compares to Other Sneakers
The Nike Air Max Plus fits at the same numerical size as Air Jordan 1, Air Jordan 3, Air Jordan 4, Air Jordan 5, Air Jordan 6, Air Jordan 11, Nike Air Max 90, Nike Air Max 1, Air Max 95, Air Max 97, Air Max 270, Nike Dunk Low, Nike Dunk High, SB Dunk Low, Nike Blazer Mid '77, adidas NMD R1, adidas YEEZY Boost 350 V2, adidas Ultraboost 4.0, and New Balance 574. According to Feetlot data, all of these round to the same size in 0.5 increments.
The shoes that run larger in number than Air Max Plus: Nike Air Force 1, Vans Authentic, Converse Chuck Taylor Ox, adidas Superstar, and Sperry Authentic Original all run about half a size smaller in number — if you wear AM Plus in 10, take 9.5 in those. Clarks Desert Boot runs about a full size smaller in number.

Common Sizing Mistakes
- Buying AM Plus in your AF1 size. AF1 runs about half a size smaller in number than AM Plus. If you wear AF1 in 10, take AM Plus in 10.5.
- Assuming Vans and AM Plus are the same size. Vans Authentic runs about half a size smaller in number than AM Plus. If you wear Vans in 10, take AM Plus in 10.5.
- Sizing up for the "strap fit." The heel straps anchor the foot at true length. Sizing up half makes the straps feel loose without improving forefoot room.
- Expecting the toe cap to break in. The structured toe overlay holds its shape. Don't size small expecting the toe cap to open — go up half for wide feet.
- Carrying your Converse or Superstar size over. Both run about half a size smaller in number than AM Plus. If you wear Chuck or Superstar in 10, take AM Plus in 10.5.
How Feetlot Computes These Numbers
Every Air Max Plus 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 AM Plus size.
This works better than the pairwise approach you'll see on most sneaker blogs because Feetlot uses the entire wardrobe graph. 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.
