The asics UB13-S GEL-SD-LYTE is a collaborative design project between asics SportStyle and the Kiko Kostadinov Studio, focusing heavily on conceptual design rather than classic sneaker aesthetics. The color gradients are inspired by industrial sculptures and are intended to reflect natural phenomena such as sunsets, moonlight, and the depths of the ocean. The upper also incorporates a “shell” concept—inspired by the structure of a seashell with an inner membrane—which gives the shoe a layered, organic look. Technically, the model is based on FLYTEFOAM PROPEL cushioning, which ensures a lightweight, responsive running experience and enhances everyday comfort.
