KEEN and Space Available Debut Earth Day UNEEK 360 in Azure Blue

KEEN’s UNEEK 360 has always looked like a shoe built for people who want utility to read as style, and Space Available pushed that idea further in Azure Blue and Star White. The first-ever product partnership between the two labels landed on Earth Day with red and yellow interlocking cords, a hand-sewn co-branded tongue label, and recycled-material charms that make the silhouette feel less like trail gear and more like an object you would actually build a fit around.

That matters because the UNEEK 360 is not just another sustainability story wrapped in cleaner branding. KEEN says it is the brand’s first solvent-free shoe, built from four main parts: a removable knit upper, an external cord cage, a drop-in footbed, and a hybrid rubber-foam outsole. The upper uses recycled plastic bottles, while the cord system allows the shoe to be mechanically assembled rather than bonded with adhesives. In practice, that gives the sneaker a harder edge and a more interesting lifecycle story, since KEEN says the design was made with end-of-life disassembly in mind.

The numbers back up the pitch. The shoe launched globally on April 22, 2026 for ¥25,300, about $160, a price that sits squarely in the premium sneaker lane without crossing into luxury absurdity. KEEN Japan listed the weight at 308 grams per shoe in a size 27cm, which helps explain why the UNEEK has remained one of the brand’s most recognizable hybrid shapes: it feels engineered, but not bulky. The shoe is being sold through KEEN Japan, Space Available retail locations, and select direct and online channels, and a launch pop-up and installation was scheduled for the evening of April 22 at Space Available’s store.

For KEEN, the collaboration extends a much larger clean-materials push. The company says its Detox the Planet effort began in 2014 and has involved more than 11,000 hours of work and over $1.2 million in investment to eliminate PFAS and other harmful chemical classes from its footwear. The UNEEK line itself dates back to 2014, which makes this new version feel less like a one-off remix and more like a sharpened second life for a signature shape.

Space Available, founded in 2020 in Bali by Daniel Mitchell, the English designer and co-founder of LN-CC, brings the right kind of tension to the project. Its reputation was built on upcycling, recycling, and closed-loop design, and the Tokyo record-shop campaign film gives the release cultural texture instead of the usual eco platitudes. This is the rare sustainability collab that still feels fresh because the product is genuinely distinctive.
