The latest update to our high-cushion trainer now delivers its softest, lightest, and most responsive ride ever. The refreshed and streamlined upper is designed with an engineered mesh made of 30% recycled materials, equivalent to three 16 oz. plastic water bottles in every pair. We upgraded the two-piece midsole with our new and improved ZipFoam&trade formula, featuring a softer step in feel right below the foot, with a firmer and more stable ride against the ground. Phantom 3 is perfect for go-long daily miles and comfortable enough for all-day wear.
