The new Phantom 4, our neutral shoe with maximum cushioning, offers an even smoother, more responsive, and comfortable run. The new design of the upper, midsole, and outsole gives the shoe a flowing and dynamic appearance. We have increased the sole height by 2 mm, now achieving a platform of 35 to 30 mm for even more generous cushioning. Our ZipFoam™ foam is lighter, softer, and more responsive than ever before. The Topo Athletic Phantom 4 is perfect for your daily outings, whether running, walking, or for all-day wear. You and the Phantom 4 are a perfect team. Together, nothing can stop you.
