It is all about a comfortable ride with the Magnify Nitro running shoes, and this season they have been retooled with an engineered mesh upper and combined it with a new cat s tongue material to keep your feet secure. Constructed with the thickest piece of Nitrogen-injected Nitro Foam in the midsole along with a layer of the sturdy ProfoamLite, this shoe is built for long runs where comfort is your top priority.
