The Adimule is adidas's cork-footbed mule — and because it's an open-back slip-on, sizing works a little differently than a laced sneaker. Here's how it fits, plus a straight answer on the half-size question.
Does the Adimule run true to size?
Yes — adidas lists it as true to size, and that matches what wearers report. Because it's an open-back mule with no heel counter and no laces, the fit is driven entirely by how the forefoot strap-over sits and where your foot lands on the footbed. Your foot rests in the contoured cork bed and the back stays open, so there's no heel lockdown to adjust. Order your usual size.
Does the Adimule come in half sizes?
This is worth being precise about, because the answer is "sort of." The Adimule is sold on a slide-style size run that is not a clean, every-half-size grade — it's graded on a slide/unisex last, so several sizes are offered only as whole sizes, with just a few half sizes scattered through the run. In other words, don't assume your exact half size exists. If your size isn't available as a half, or you're genuinely between sizes, size up, not down — on an open-back mule there's no heel to hold a too-small shoe on, and you don't want your foot overhanging the footbed.
How it fits and what it is
The Adimule is a slip-on, open-back mule in the Birkenstock mold: a suede forefoot cover over a cork midsole with a suede footbed, on a rubber Adilette-style diamond-tread outsole. It's sold as a women's adidas Originals style. The contoured cork bed means it gets more comfortable as it molds to your foot, like a classic cork footbed does.
Quick guidance
Order your normal size. If only whole sizes are offered near yours, or you're between, size up so the footbed fully supports your foot. Don't size down chasing a snugger fit — there's no heel to keep it on.

Final verdict
The Adimule fits true to size — order your usual size. The size run isn't a full every-half-size grade, so if your half isn't offered or you're between, size up rather than down.
