On Running Cloudswift 4 AD, Black

Swiss-engineered finesse. On Running’s Cloudswift 4 AD is the natural evolvement of the Cloudswift 3 AD. The upper features an updated cage construction that offers up better midfoot lockdown, while a perforated toe box and rocker geometry add utilitarian qualities. Underfoot, a dual-density Helion superfoam midsole and nylon-blend Speedboard provide soft landings as well as impeccable responsivity. | 3MF10571043
