adidas Campus 2 Sizing: Run Big or Small?
Add the shoes you already own and Feetlot predicts your size in the adidas Originals Campus 2 and 2,000+ others, from 100,000+ verified owner pairs.
The adidas Originals Campus 2 fits very close to the Nike Air Force 1 and runs just slightly small for most people. Based on 95 verified pairs in the Feetlot database, the typical wearer stays true to size. If unsure: buy your normal size, but if you have wide feet or land between sizes, go half a size up, because the narrow suede upper and flat last leave little wiggle room.
adidas Campus 2 Sizing, What the Feetlot Database Tells Us
The adidas Campus 2 is a well-tracked suede court silhouette in the Feetlot database. Across the 95 verified pairs on record, the fit pattern is consistent: the Campus 2 sits right next to the Nike Air Force 1, Feetlot's reference shoe, and lands just a hair smaller. In plain terms, if a wearer is true to size in the Air Force 1, they are true to size (or a touch snug) in the Campus 2. The classic "Campus runs a little small, but most people stay true to size" advice you hear repeated everywhere lines up with what Feetlot data actually shows.
What makes the Campus 2 feel snug is build, not length. The flat skate-style last has a low-volume toe box, and the suede upper is narrower and less forgiving than the leather on an Air Force 1. That is why slim and standard-width feet are comfortable true to size, while wide or in-between feet feel the pinch and do better half a size up.
Should You Size Up or Down in adidas Campus 2?
Standard fit (most people)
Stay true to size. For the average foot the Campus 2 fits very close to a true-to-size Air Force 1, running only slightly small. Buy your normal adidas size and expect a clean, secure fit that the suede relaxes into over the first few wears.
Wide feet
Go half a size up. The Campus 2 is built on a flat, narrow last with a low toe box, and the suede upper does not splay outward the way softer leather does. A half size up buys width and depth across the forefoot without leaving the heel sloppy.
Narrow feet
True to size is the right call, and the slim suede upper actually works in your favor here, it wraps a narrow foot closely instead of leaving dead space. Only step up half a size if your toes feel cramped against the front.
In-between sizes
If you normally fall between two sizes, round up to the larger one in the Campus 2. Because the last is flat and the suede has limited give in length, sizing down to the smaller number tends to feel short rather than snug.
How adidas Campus 2 Compares to Other Shoes
According to Feetlot data, the Campus 2 fits almost identically to a few familiar sneakers. It sits within a hair of the Vans Authentic and the Nike Air Max 97, take the same size in all three. It also lines up with the Air Force 1 itself, running just slightly smaller, so wearers true to size in the AF1 stay true to size here.
Against more structured footwear, the Campus 2 runs smaller. Owners who have both in the Feetlot database tend to take a larger number in the Campus 2 than in the Converse Chuck Taylor, and a notably larger number than in the Clarks Desert Boot, so if your Chucks or Clarks fit well, do not assume the same number translates down to the Campus 2. The same holds for classic leather dress shoes such as Allen Edmonds and Johnston & Murphy oxfords, where wearers also size up to reach the Campus 2 fit.

Common Sizing Mistakes
- Sizing down expecting a roomy fit. The Campus 2 already runs slightly small on a flat, narrow last, going down makes it short, not snug.
- Copying your Converse or Clarks number. Feetlot data shows the Campus 2 runs smaller than both, so the same number will feel tight.
- Ignoring width. Wide and in-between feet should go half a size up; the suede upper does not stretch outward the way leather does.
- Buying snug expecting the suede to grow. The Campus 2 suede softens and molds, but it does not gain length, size for the fit you need on day one.
How Feetlot Computes These Numbers
Every adidas Campus 2 sizing recommendation on Feetlot is the output of a global offset model fit to over 100,000 verified shoe records. Each shoe gets a single number, its "size offset", that captures how much its sizing drifts from the 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 Campus 2 size. This works better than a simple pairwise lookup because Feetlot uses the entire wardrobe graph: even when two users share no shoes directly, the chain of users between them transmits a consistent recommendation. That is why a shoe with a modest number of direct owners still gets a stable size estimate.
