The ASICS Gel Quantum Lylia is a collaboration between Bulgarian-born designer Kiko Kostadinov and the Japanese fashion label Hysteric Glamour. The black mesh upper features tonal synthetic leather overlays and a lacing system borrowed from the Skysensor Slash JJ for a secure fit. An oversized spiral logo in blue and metallic silver adorns the tongue, complemented by a heel emblem showcasing dual Hysteric and Kiko Kostadinov branding. The foam midsole is finished in electric blue and includes visible Gel cushioning for ultimate comfort.
