It’s all about a comfortable ride with the Magnify NITRO from Puma, and this season they have 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 a thick piece of nitrogen-injected foam NITRO in the midsole along with a layer of the sturdy PROFOAMLITE, this shoe is built long runs where comfort is your top priority.
