The Nike Blazer Mid '77 fits true to size for most Nike wearers but runs about half a size smaller than Air Force 1. Based on 2,120 owner-reported pairs in the Feetlot database, the typical wearer takes the same number in Blazer Mid '77 as in Air Jordan 1, Air Max 90, or SB Dunk Low. If unsure: order true to size from your Nike size. Wide feet should size up half — the slim retro last is the narrowest in Nike's lifestyle lineup.
Blazer Mid '77 Sizing — What 2,120 Pairs in the Feetlot Database Tell Us
The Nike Blazer Mid '77 is one of the most-tracked retro Nike silhouettes in the Feetlot database. Across 2,120 owner-reported pairs, the residual variance is tight (standard deviation ≈ 0.23 size units), but the spread between narrow-footed and wide-footed wearers is wider than for the AM90 — the Blazer's vintage last is genuinely narrow, and that shifts the right answer for some buyers. Within Nike's lineup (AJ1, AM90, AM97, SB Dunk Low, Dunk Low and High), the Blazer fits at the same numerical size; against Air Force 1 it's half a size smaller.
The shape is the headline. The Blazer's last is built to a 1977 basketball pattern — long, low-volume, and slim through the forefoot. The leather upper has minimal stretch, the rubber midsole is flat and thin, and the swoosh and panels are stitched directly to the upper without padding. Wearers with average-width feet find the Blazer fits at TTS; wide-footed wearers find half up necessary regardless of comparison shoe.
Should You Size Up or Down in Blazer Mid '77?
Standard fit (most people)
True to size from your Nike size. According to Feetlot data, the typical Blazer Mid '77 wearer takes the same number they wear in Air Jordan 1, Air Max 90, SB Dunk Low, or Air Max 97. The slim last and stitched-on swoosh leave little length to spare, so going down half cramps the toe; going up adds length the leather won't tighten back.
Wide feet
Size up half. The Blazer's vintage last is the narrowest in Nike's lifestyle lineup — narrower than AM90 and significantly narrower than AF1. Half up gives the leather room to drape across the metatarsals without the swoosh stitching biting in. A full size up overcorrects and produces heel slip; half is the sweet spot for wide feet.
Narrow feet
True to size or half down. Narrow-footed wearers find the slim last actually flatters their foot at TTS — there's no extra width to fill in. Going down half a size is uncommon but workable if you prefer a snug, board-feel fit; the laces have enough range to lock in either way.
Blazer Low '77 and Blazer High variants
The Blazer Low '77 uses the same length last as the Mid '77 — same number, no adjustment needed. The Blazer High uses the same last but with an additional collar height; same length sizing applies. Vintage Suede, Vintage White, and Sketch variants all use the standard Blazer last. Premium models with thicker suede or padded collars don't change the sizing recommendation.
How Blazer Mid '77 Compares to Other Sneakers
The Blazer Mid '77 sits in the small end of the Nike lifestyle pack and matches most other Nike silhouettes. According to Feetlot data, the same number you wear in Blazer Mid '77 also fits Air Jordan 1, 3, and 4, Air Max 90, 1, 95, 97, and 270, SB Dunk Low, Nike Dunk Low and High, YEEZY Boost 350 V2, NB 574, Vans Authentic, Vans Old Skool, adidas Gazelle, and NMD R1 — all within a quarter size in raw terms.
The shoes that run noticeably larger than the Blazer Mid '77 are mostly the leather-and-canvas classics. Air Force 1, adidas Stan Smith and Superstar, Sperry Top-Sider, and Converse Chuck Taylor (Lo or Hi) all run about half a size larger than the Blazer — for those, take half a size DOWN from your usual number to land on the right Blazer Mid '77. Boots run roomier still: Clarks Desert Boot is half a size larger than the Blazer, and Red Wing Iron Ranger is a full size larger.

Common Sizing Mistakes
- Buying the same number as your Air Force 1. Blazer Mid '77 runs about half a size smaller than AF1 in Feetlot data, and the slim last makes the difference more noticeable than between AM90 and AF1. Go up half a size from your AF1 number.
- Sizing up a full size for wide feet. A full size up overcorrects — the heel slips and the laces strain. Half up is the right call for wide feet; if half up still pinches, the Blazer last just isn't suited to your foot shape.
- Confusing US Men's and Women's labels. The Blazer uses Nike's standard 1.5-size offset between men's and women's (US W = US M + 1.5). A US men's 9 is a US women's 10.5.
- Treating the Blazer Low and Mid as different sizes. Both use the identical length last; only the collar height differs. Take the same number in Low, Mid, and High.
- Buying small expecting the leather to widen. The Blazer's leather softens in width by 2–4 mm over 10 hours of wear, but doesn't change in length. If the toe pinches at TTS, the answer is half up — not break-in.
How Feetlot Computes These Numbers
Every Blazer Mid '77 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 much its sizing drifts from the reference shoe (the Air Force 1). When a Feetlot user provides their size in any tracked sneaker, the model recovers their true foot baseline and recommends the matching Blazer Mid '77 size.
This works better than the more common pairwise approach because Feetlot uses the entire wardrobe graph. A Vans Authentic owner contributes data about how Vans fits relative to Air Force 1 owners (who often own both), which links back to Blazer Mid '77 owners. 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.
