First introduced in 2014, the GEL-CUMULUS 16 was originally known for its soft, smooth cushioning designed for long-distance running. The upper features a mix of glossy synthetic leather, seamless panel construction, and open mesh underlays. This combination creates a technical aesthetic that reflects the modern running shoe design language of the 2010s. Its signature plush ride remains intact, supported by dual GEL cushioning units, FLUIDRIDE technology, and FLYTEFOAM cushioning to deliver lasting comfort with every step.
