Converse Chuck Taylor All Stars run about half a size large for most. Based on 3,776 owner-reported pairs in the Feetlot database, the typical wearer takes half a size down from their usual sneaker size for a clean, lace-friendly fit. If unsure: size down half a size. Wide feet should stay true to size, since the canvas has minimal width give — Converse stocks dedicated wide-fit silhouettes if needed.
Chuck Taylor All Star Sizing — What 3,776 Pairs in the Feetlot Database Tell Us
The Converse Chuck Taylor All Star is one of the most-owned shoes in the Feetlot database. Across 3,776 owner-reported pairs, the residual variance is tight (standard deviation ≈ 0.23 size units), meaning fit is consistent across body types. The "size down half" advice that's been Converse folklore for decades lines up exactly with what Feetlot data shows: the typical Chuck Taylor wearer takes a number half a size below what they wear in most other lifestyle sneakers.
The pattern is structural. Chuck Taylors use a vintage canvas-and-rubber construction with a flat midsole and a long, slightly tapered last. There's no foam padding inside the heel cup, no engineered insole, and no shaped toe box, so the shoe has more interior length than its number suggests. Sizing down half a size compensates for that without compromising the silhouette.
Should You Size Up or Down in Chuck Taylor?
Standard fit (most people)
Size down half. According to Feetlot data, the typical Chuck Taylor wearer takes half a size below their everyday sneaker number — for a wearer who's a 10 in Air Max 90 or YEEZY 350 V2, the right Chuck Taylor size is 9.5. The flat insole and unpadded heel make a true-to-size purchase feel slightly long and loose at the back of the foot.
Wide feet
Stay true to size, or look at the Wide-fit silhouettes. The Chuck Taylor's canvas upper has almost no width give over time — unlike Vans Authentic canvas, which softens significantly. For wide-footed wearers, sizing down half cramps the forefoot. True to size relieves the width pressure but leaves a touch of length slack — many wide-footed Chuck wearers accept that trade-off, or buy the dedicated Wide-fit version Converse stocks.
Narrow feet
Half down works well. The shoe is already on the narrow side, and the lacing system has enough range to lock in narrow feet at half a size below normal. Going a full size down is also common among narrow-footed wearers — but only when paired with thicker socks or aftermarket insoles, since the canvas tongue won't compensate on its own.
Chuck Taylor Hi (high-top) and other variants
The Chuck Taylor Hi uses the same length sizing as the Lo / Core Ox — same number, same fit through the foot bed. According to Feetlot data, Hi owners take the same number as Lo wearers (within 0.05 size in raw terms). The collar adds ankle pressure, not length pressure. Chuck Taylor 70 (the premium reissue) and Chuck Taylor II also use the same length last as the standard Core Ox.
How Chuck Taylor Compares to Other Sneakers
The Chuck Taylor sits half a size larger than most lifestyle sneakers. According to Feetlot data, most wearers take their Chuck Taylor size as half a size below the number they wear in Air Jordan 1, 3 and 4, Vans Authentic and Old Skool, Air Max 90, 95, 97 and 270, Air Max 1, Blazer Mid '77, SB Dunk Low, Nike Dunk Low and High, YEEZY Boost 350 V2, adidas Gazelle, NMD R1, and New Balance 574. In practice, take your "everyday" sneaker number and drop half.
A handful of shoes sit at the same numerical size as Chuck Taylor. Air Force 1, adidas Stan Smith and Superstar, Sperry Top-Sider Authentic Original, Clarks Desert Boot, and the Chuck Taylor Hi all align within a quarter size of the Chuck Taylor Lo in raw terms. Boots that run roomier still — Red Wing Iron Ranger most notably — go the other way: take your Chuck Taylor size half above your Iron Ranger number.

Common Sizing Mistakes
- Buying the same number as your other sneakers. Chuck Taylor runs about half a size larger than nearly every other lifestyle sneaker in the Feetlot database. Taking your Air Jordan 1 or Vans Authentic size in Chuck gives a heel that slips and a length that pinches the laces shut.
- Expecting the canvas to stretch. Unlike Vans canvas, Chuck Taylor canvas barely gives over time. Don't buy half down hoping it'll widen — the tightness on day one is the tightness in year three.
- Confusing US Men's and US Women's labels. Chuck Taylor uses a 2-size offset between men's and women's (US W = US M + 2), not the standard 1.5 most sneaker brands use. A US men's 9 is a US women's 11, not 10.5.
- Treating Hi and Lo as different sizes. Chuck Taylor Hi and Lo / Core Ox use the same number — only the collar height differs. Don't assume the Hi runs tighter and size up; the foot bed is identical.
- Ignoring the Chuck 70 distinction. Chuck Taylor 70 is the premium reissue with a thicker sole and slightly more cushioning, but it uses the same length last as the standard Chuck Taylor. Same size in both.
How Feetlot Computes These Numbers
Every Chuck Taylor 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 Chuck Taylor size.
This works better than the more common pairwise approach because Feetlot uses the entire wardrobe graph. A YEEZY 350 owner contributes data about how YEEZY fits relative to Air Force 1 owners (who often own both), which links back to Chuck Taylor 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.
