It’s all about a comfortable ride with the Magnify NITRO, and this season we’ve retooled the model with an engineered knit upper and even more NITRO. Constructed with PUMA's thickest piece of nitrogen infused NITROFOAM in the midsole, this shoe is built for long runs where comfort is your top priority. PUMA has even tossed in an extra amount of rubber placements for added durability while you log miles.
