It is all about a comfortable ride with the Magnify Nitro running shoes, and this season Puma retooled this model with an engineered mesh upper and combined it with a new cat's tongue material to keep your feet secure. Constructed with the thicket piece of nitrogen-injected Nitro foam in the midsole along with a layer of the sturdy ProFoam Lite, these shoes are built for long runs where comfort is your top priority.
