ASICS and Cecilie Bahnsen turn GEL-QUANTUM 360 I into floral slip-on sneaker

ASICS took one of its most technical runners and gave it Cecilie Bahnsen’s soft-focus touch. The GEL-QUANTUM 360 I was recast as a slip-on, lace-less sneaker with a flower cut-out where the tongue and laces would usually sit, turning a performance shoe into something cleaner, lighter and far more fashion-minded.

The design arrived in two colorways, baby pink and jet black, and that split tells you exactly who each pair is for. The pink version leans into Bahnsen’s prettiest instincts, the kind that reads as effortless with a satin skirt, wide-leg trousers or even gym gear that wants a softer finish. The black pair is the sharper buy: still floral, still sculptural, but restrained enough to sit comfortably with cargo pants, nylon track trousers or the kind of all-black wardrobe that powers modern streetwear. Both keep the monochrome floral detailing that gives the collaboration its edge.

The release landed on April 18 at ASICS and select retailers, and it feels like one of the week’s cleaner fashion-sneaker plays because the idea is so simple. Instead of piling on gimmicks, ASICS and Bahnsen removed the usual sneaker hardware and let the silhouette breathe. ASICS’ release materials frame the shoe as a blend of technical innovation and Bahnsen’s modern femininity, while Bahnsen’s own product page pushes the idea of movement between function and form, built for the rhythm of contemporary life.

That balance matters because the shoe is not just a pretty remaster. ASICS says the GEL-QUANTUM 360 I debuted in 2015 and was the first ASICS shoe to feature 360-degrees of GEL technology in the midsole. That archival detail gives the collaboration some weight: this is not a brand borrowing a runner’s shell for decoration, but a proper ASICS engine being dressed for the fashion floor.

It is also a continuation of a partnership that began in 2023 and has already moved well beyond one-off novelty. Bahnsen said a 2024 ASICS collaboration launched during the Paris 2024 Olympic Games and reworked the GEL-QUANTUM 360 VIII into a sandal, marking the first-ever women’s model of that silhouette. The new GEL-QUANTUM 360 I keeps that momentum going, but with a more wearable pitch and a more convincing day-to-day case.

At A$400.00 in Australia, the shoe sits squarely in premium territory, but the proposition is sharper than many fashion-sneaker collaborations at that level. The black pair will travel farther across wardrobes and trends. The pink pair is the one for people who want the collaboration to announce itself. Between them, ASICS and Cecilie Bahnsen have made a rare sneaker that can move from gorpcore to a dressed-up city uniform without losing its point.
