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 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.
The Black/Gum Adimule (JQ4367) is a good illustration of exactly that: its run is graded in whole sizes from 4 through 14, with no halves at all. If you normally wear a half size, that's the run where you'd round up.
The colorways
Two makeups worth knowing. The Golden Beige is the tonal, natural-material version — cream leather over the cork and gum, the quieter of the two, and it's listed in unisex US sizing. The Black/Gum pairs a black leather upper with the same cork sole and gum outsole, and is listed in US men's sizing. Same shoe underneath — leather upper, textile lining, cork sole with a suede footbed, rubber outsole — so the choice is really tonal-and-warm versus dark-and-clean.
How it fits and what it is
The Adimule is a slip-on, open-back mule in the Birkenstock mold: a covered forefoot over a real cork sole with a suede footbed, on a rubber outsole. The combination of cork, suede and gum rubber gives it a slightly broken-in feel out of the box — the contoured cork bed then keeps molding to your foot the way a classic cork footbed does. Check which size run a given colorway uses before you order, since some are listed as unisex and some in men's sizing.
One thing worth clearing up: it's open at the back, not the toe. The Adimule has a closed toe, which is why it works well past summer and sits closer to a casual clog than a pool slide.
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.
How to style it
The tonal, natural-material look is the appeal on the Golden Beige — cork, suede and gum rubber in one neutral palette, easy with washed denim, fatigue pants, or loose sweats. The Black/Gum plays it straighter: it works with black shorts and a white tee, or with relaxed trousers when a standard athletic slide feels too casual. Either way the closed toe means it doesn't read as strictly warm-weather footwear.

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.
