Crush your daily miles in the Topo Atmos 2—the plush, high-cushion running shoe that keeps comfort front and center without sacrificing speed. The upgraded 40 x 35 mm platform packs springy ZipFoam™ technology for a soft yet energetic feel, while the redesigned outsole grips harder and weighs less. Wrapped in recycled engineered mesh, your foot gets a secure, breathable hug that handles long runs and longer days with ease. It's everything you loved about the original, now lighter, grippier, and dialed in for peak performance.
