About the release
adidas x size? is continuing the ongoing size? Archive series with a proper pair of grail-tier ZX drops. The size? Exclusive adidas Originals Archive adidas ZX8000 Pack revives two prototype-referenced ZX 8000 colourways — the 'Proto Aqua', restoring one of the heavily speculated unofficial Aqua samples from the coveted OG 1989 line-up, and the 'Proto Germany', a reworked take on the 1998 Germany national team-inspired colour way. Style codes KZ8256 (Aqua) and LA0975 (Germany).
The pack follows on from the Archive series' recent Oregon Ultra Tech in faux ostrich leather revival, and continues the 2026 theme of paying tribute to evasive grails from adidas's past. The ZX 8000 has been a size? staple since the retailer's doors first opened in 2000, and both pairs stay true to the OG construction — sheeny mesh foundations, intersecting suede overlays, TPU heel cages, Torsion bar units underfoot and lugged rubber outsoles. Retail is £110 per pair.
UK release is Friday 7 August 2026 for £110 each via size? in-store and online, as a size? Exclusive. Unisex sizing.

adidas ZX 8000 Archive 'Proto Aqua' — Design and details
The 'Proto Aqua' restores one of the unofficial Aqua samples from the coveted OG ZX 8000 line-up that debuted back in 1989. It's an ode to a prototypal colourway that never made it into a full production release — a chase-tier reference for ZX archivists. size? has stayed close to the original speculated sample execution, with some altered colour blocking.
Aqua mesh base and TPU heel cage
The upper leads with a bright aqua blue mesh foundation, letting the base colour do most of the visual work. Intersecting suede overlays shape the panel structure, and a TPU heel cage provides the shoe's signature rear support. The mesh construction gives the shoe its lightweight, breathable feel — a proper late 80s running silhouette translated cleanly into a lifestyle context.
Purple and yellow accents
Purple and yellow accents punch through the aqua base across the branding, overlays and detailing. size? has switched the placement of the purple and yellow hits from what appeared on the original speculated sample, giving this reissue a slightly refreshed colour balance while keeping the palette faithful.
Torsion tech underfoot
The Torsion bar unit sits underfoot, one of adidas's flagship late-80s technologies. It's a supportive TPU plate through the midfoot that allows the heel and forefoot to move more independently — increasing rotary resistance between the two zones. It's what made the ZX 8000 a proper technical running shoe at debut, and it remains a defining underfoot detail. A lugged rubber outsole completes the shoe.
adidas ZX 8000 Archive 'Proto Germany' — Design and details
The 'Proto Germany' colourway hails from 1998, originally mirroring the Deutschland national football team's classic jersey hues. There have been a couple of retro re-releases since, most recently in 2022. This 2026 version reimagines the archival sample colour blocking to give the ZX community something nostalgic and collectable — same national colour theme, rearranged panel placement.
Red, black and yellow colour blocking
The base runs a black mesh foundation with black side panels and toebox — a darker overall base than earlier Germany executions. A red suede toe, red lace, and red heel panel match the red Three Stripes, giving the shoe its strongest visual accents. Yellow hits pop throughout the detailing, completing the German national colour theme. The reworked balance leans darker than the OG 1998 build, making it more everyday-wearable than a straight retro.
Mesh and suede construction
Consistent with the Aqua pair, uppers are constructed from mesh with layered suede tooling. Small design details — including Trefoil-branded tongue tabs — stay true to the OG specifications. It's a faithful ZX 8000 build with just enough contemporary colour balance to sit in a modern rotation.
Tonal black outsole
Underneath, a tonal black rubber outsole provides trail-rooted grip. Combined with the Torsion bar unit, the shoe is built for all-day comfort and dependability — same core tech as the Aqua, different colour direction.

The ZX 8000's cultural weight and size?'s Archive programme
The adidas ZX 8000 first released in 1989 and became one of the defining models from the brand's wider ZX running series. Its arrival helped bring Torsion technology to a wider audience — the TPU midfoot plate letting the heel and forefoot move independently in a way that felt radical for running shoe engineering at the time. That technical genuineness is what gave the model its longevity beyond the sport it was designed for.
The ZX 8000's cultural weight in Europe runs deeper than most similar-era running silhouettes. Bright ZX colourways became closely tied to Germany's underground club scene in the years following the fall of the Berlin Wall — the ZX 8000 in particular became one of the shoes most associated with that late 80s / early 90s European club culture. That's the specific cultural memory the size? Archive pack is tapping into. It's more than just a retro — it's a chase of a specific era's aesthetic.
The 2026 size? Archive series has been pointed and specific across the year, with the ZX 8000 pack sitting alongside earlier releases like the Oregon Ultra Tech faux ostrich leather revival. size? has been an adidas retail partner since it opened in 2000, and its exclusives are widely considered some of the sharpest adidas archive work coming out of the UK. These two ZX 8000 pairs fit that legacy properly.
