The UB13‑S GEL‑SD‑Lyte, designed in conjunction with the Kiko Kostadinov Studio, reinterprets the GEL‑SD silhouette through a stripped-back, laceless slip-on construction that wraps the foot in one seamless motion. Its shape takes inspiration from an egg—pairing a structured exterior with a softer interior.
Layered mesh and synthetic overlays reference the original SD‑Lyte shell, creating depth and sculptural tension, while the midsole features FLYTEFOAM PROPEL cushioning and GEL® technology in the heel for responsive impact absorption. The staggered, sculpted outsole provides stability and subtle visual drama, complementing the low-cut silhouette.
