The adidas Originals Campus 2 runs slightly small but very close to true to size for most people. Based on 95 verified pairs in the Feetlot database, it sits almost exactly where the Nike Air Force 1 does — just a touch snugger. If unsure: stay true to size in your normal adidas size, but go half a size up if you have wide feet or fall between sizes, because the suede upper and flat last run narrow and snug.
adidas Campus 2 Sizing — What the Feetlot Database Tells Us
The Campus 2 is one of the most-tracked suede court sneakers in the Feetlot database. Across 95 verified pairs, the fit pattern is steady and predictable: it runs just slightly small, with a measured offset of +0.12 against the Nike Air Force 1, Feetlot's reference shoe. In plain terms, that means the Campus fits almost identically to the AF1 — only a hair snugger. The widely repeated "true to size" advice holds up in Feetlot data, with one caveat that comes up again and again: the suede upper and flat last make the shoe feel narrow, so people between sizes or with wide feet feel the squeeze before they feel any length problem.
Should You Size Up or Down in adidas Campus 2?
Standard fit (most people)
Stay true to size. With a small +0.12 offset from the Air Force 1, most wearers buy their normal adidas size and get a clean, secure fit. The Campus 2 is built on a flat, low-volume last, so a true-to-size pair locks the heel and midfoot without feeling loose. The suede gives very little over time, so do not expect length to change with wear.
Wide feet
Go half a size up. This is the single most common Campus adjustment in Feetlot data. The flat last and snug suede toe box leave wide-footed wearers short on width, and since adidas does not offer a wide variant of the Campus, a half size up is the practical way to buy back room across the forefoot.
Narrow feet
Stay true to size. The low-volume last already hugs a narrow foot well, so there is no need to size down. Sizing down on a flat last like the Campus usually costs toe room before it improves the lockdown.
Between sizes or the Campus 00s
If you fall between sizes, round up. The narrow suede build means the smaller half size will feel tight first. The Campus 00s shares the same last and sizing as the Campus 2, so the same guidance applies — true to size for most, half a size up for wide feet or for in-between sizes.
How adidas Campus 2 Compares to Other Shoes
According to Feetlot data, the Campus 2 fits within a hair of the Vans Authentic — owners who have both in the Feetlot database tend to take essentially the same size, with the Campus running a touch smaller. It runs about half a size smaller than the Converse Chuck Taylor (Core Ox), which is known to run long, so you would take a slightly bigger number in the Campus than in your Chucks. The gap to the Clarks Desert Boot is larger still: the Campus runs meaningfully smaller, so the Desert Boot's roomy, longer last means you take a smaller number there than in the Campus. In short, treat the Campus like a Vans Authentic for sizing, expect to go up slightly from your Converse, and do not carry a Desert Boot size straight over.

Common Sizing Mistakes
- Sizing up by default. The Campus runs only slightly small — most people stay true to size. A full size up leaves the heel sloppy on the flat last.
- Ignoring width. The complaint with the Campus is almost always width, not length. If your foot is wide, fix it with a half size up, not a full size.
- Buying small expecting the suede to stretch. The suede upper softens but barely lengthens — a too-short pair stays too short.
- Carrying a boot size straight over. A Clarks Desert Boot runs longer and roomier; using that number in the Campus will overshoot.
How Feetlot Computes These Numbers
Every 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.
