About the release
Experimental footwear label Empty Behavior has linked with ASICS for the first official collab on the Hypersync — a slim, low-profile silhouette inspired by old-school wrestling and track and field shoes. The collab does something unusual with one of ASICS' most recognisable design signatures, reimagining the iconic tiger stripes as ruffled fabric frills. It's a small detail with a big impact: balletcore meets industrial precision in a properly considered package. Style code 1203B146-001.
The 'Black Breeze' colourway runs in a moody black base with unexpected pops of soft pink. The upper mixes synthetic leather overlays with open-weave air mesh for a layered, breathable build, finished with a heavily padded tongue and an ultra-thin barefoot-style rubber sole that keeps the silhouette close to the ground. Dual co-branding sits across the toe box, with the Empty Behavior logo stamped on the heel. The release also drops in a clean White/Silver variant (1203B146-100) as the second pack colourway.
UK release is Thursday 2 July 2026 for £100 via ASICS and select retailers. China and Hong Kong get early access on 27 June.

Design and details
The Hypersync's foundation is athletic and slightly aggressive — built on the design language of combat sports footwear, with a low-profile sole and a stripped-back silhouette. Empty Behavior's job here was to flip that reading without losing the bones of what makes the shoe work. The result is one of the more genuinely interesting collab decisions of the year.
Ruffled fabric frills
The headline detail. Where the standard Hypersync (and most ASICS silhouettes) carries a clean tiger stripe as the lateral branding element, this collab replaces it with a ruffled fabric frill. The frill runs down the side panel in the exact placement and orientation the tiger stripe would normally hold, turning a sport-derived design cue into something that reads closer to ballet or lingerie design. The juxtaposition is the point — feminine, romantic detail on an athletic combat-sport silhouette.
Upper construction
The upper layers synthetic leather overlays over an open-weave air mesh base. The leather sits at the structural points — toe, mudguard, heel — while the mesh handles the panels that need ventilation. The combination keeps the build technical and breathable while reading as more crafted than a standard performance silhouette. Soft pink accents thread through the black base as the colourway's primary contrast moment.
Padded tongue and branding
A heavily padded tongue sits across the lacing zone — a deliberate contrast to the otherwise minimal silhouette. Dual Empty Behavior x ASICS branding appears on the toe box, with the Empty Behavior logo stamped on the heel in a quieter execution. The branding stays restrained, letting the frill carry the visual identity.
Barefoot-style sole unit
Underfoot, the Hypersync runs an ultra-thin, barefoot-style rubber sole unit. There's no chunky cushioning, no visible Gel, no oversized midsole structure — just a stripped-back, close-to-the-ground build that honours the silhouette's wrestling and track shoe DNA. The minimal sole is what gives the Hypersync its slim, almost loafer-like profile, and Empty Behavior hasn't tried to alter it.

The Black Breeze and White/Silver pack
The 'Black Breeze' is the headline of a two-pair release. The companion White / Silver colourway (1203B146-100) takes the same silhouette and ruffled frill construction and reframes it in a lighter, cleaner palette — closer to a wedding-shoe or ballet-flat reading. Same upper construction, same barefoot-style sole, same Empty Behavior x ASICS co-branding placement.
Both pairs drop on 2 July 2026 globally. The Black Breeze leans into the contrast between dark, tactical streetwear and soft balletcore detailing. The White/Silver leans into pure romance. The two pairs work as a pack but neither needs the other to make sense.
Empty Behavior and the ASICS Hypersync
Empty Behavior is an experimental footwear and design label that has built a reputation for taking athletic silhouettes and re-coding them through architectural design language. The brand's approach treats every collab as a deconstruction project — pulling silhouettes apart, identifying what makes them work, then rebuilding the design language with feminine, romantic, or architecturally driven elements layered in. The ASICS Hypersync collab is one of the clearest expressions of that approach to date.
The Hypersync itself only launched earlier in 2026. ASICS designed it around the structural DNA of wrestling and track and field footwear — low-profile, lightweight, close to the ground. It's a relatively new silhouette in the ASICS lineup, so this collab is its first proper external rework. The choice of Empty Behavior as the first collaborator says a lot about where ASICS sees the silhouette sitting — closer to fashion than to performance, with room for serious design intervention.
