Originally released in 2014, the GEL-CUMULUS 16 was known for its soft cushioning on longer runs. The upper combines glossy synthetic leather overlays, no-sew panels, and open mesh for a layered, technical look inspired by performance running shoes from the 2010s. Underfoot, it keeps the comfort of the original design with dual GEL inserts, FLUIDRIDE, and FLYTEFOAM cushioning for a soft and supportive feel.
