It’s all about a comfortable ride with the Magnify NITRO, and this season we’ve retooled this model with a breathable knit upper and combined it with a new ‘cat’s tongue’ material to keep your feet secure. Constructed with our thicket piece of nitrogen-injected NITRO foam in the midsole along with a layer of our sturdy PROFOAMLITE, this shoe is built long runs where comfort is your top priority.
