OPEN YY and KEEN debut rocky-canyon ZERRAPORT II hybrid sandals

OPEN YY took KEEN’s ZERRAPORT II and sharpened its utilitarian bones into something with actual street pull: a rocky-canyon hybrid sandal that still looks built for mileage. The collaboration is KEEN and OPEN YY’s first together, and that debut matters because the two brands come at footwear from opposite angles, KEEN with function-first technicality and OPEN YY with a sharper eye for shape, styling and reinterpretation.

The ZERRAPORT II is already one of KEEN’s most practical silhouettes, an original open-air hybrid sandal from the brand’s Tokyo Design Center. Here, the familiar KEEN formula stays intact: a wide forefoot and open construction, recycled P.E.T. webbing straps, a foam insole with arch support, a light foam midsole, a multidirectional lug outsole for traction and the brand’s standard toe bumper. OPEN YY’s twist is less about changing the anatomy than changing the mood. The collection is framed around rocky canyon textures and tones, with a palette inspired by natural rock above and below water, and the result feels more like terrain translated into wardrobe language than a simple logo swap.

That distinction shows up in the two colorways on OPEN YY’s site, Burnt Henna and Seneca Rock. Burnt Henna is the stronger, red-leaning choice, the pair that gives a technical sandal enough heat to stand out against washed denim, black nylon pants or a slouchy white tee. Seneca Rock reads cooler and more khaki, which makes it the easier daily driver for olive cargos, stone drawstring trousers or light workwear shorts. Both are grounded enough to wear beyond the trail, and both keep the sandal’s useful, roomy fit intact.

Fit is the part to pay attention to. OPEN YY’s listing recommends going a half-size up, a practical note for a sandal that already leans generous in the forefoot. At 189,000 KRW, about $130, the price sits in the range where the design needs to justify itself through construction, and KEEN’s support-minded platform does most of that work. This is not a delicate fashion sandal pretending to be rugged; it is a real walking shoe with a fashion edit.

The collaboration is on sale now through OPEN YY’s official online store, flagship locations and The Hyundai Seoul, while KEEN’s wider rollout begins May 15 across its official online and offline channels. In a market crowded with hybrid sandals that often sacrifice comfort for image, OPEN YY and KEEN found the cleaner equation: keep the traction, keep the fit, then give the shoe a canyon-worn surface that feels ready for Seoul sidewalks as much as summer escape.
