Kiko Kostadinov x ASICS ILARGI FF is a collaborative sneaker that combines the Bulgarian designer’s experimental aesthetic with ASICS’ technical expertise, presenting a split-toe Tabi-style runner as part of their ongoing partnership. The ILARGI FF’s upper takes cues from traditional Japanese tabi work boots and ASICS’ marathon archives with a lightweight, technical build and a streamlined profile.
The silhouette’s most defining feature is its iconic split-toe construction, which creates a unique fit that separates the big toe from the rest of the foot. The refined lacing system integrates into a minimal tongue, and a blend of textures across the quarters and toe box adds dimension while maintaining a low-profile look. Underfoot, the sneaker uses ASICS’ FlyteFoam midsole technology for responsive cushioning and comfort across varied use cases.
