Meet Tempus—a revolutionary experience that’s the first of its kind. It’s got that incredible superfoam bounce you've been missing combined with the adaptive guidance system you need to perform at your best. Full-length core of ultralight PWRRUN PB cushioning gives you incredible spring and energy return. Contoured PWRRUN Frame starts above the midsole to support your foot upon landing, and its curved shape and forefoot ground contact give you a snappy transition as you take off. More underfoot midsole contouring lets you sit deeper into the footbed, and allows the shoe to hug your foot for an incredibly plush and supportive feel, top to bottom.
