Best for beginners who need an all-weather running shoe. The Phantom 4 WP retains the fantastic ZipFoam™ supercritical foam midsole (35mm heel/30mm forefoot) for exceptional impact absorption and joint protection. The standout addition is the eVent® waterproof membrane — perfect for rainy climates where beginners might otherwise skip runs. At ~292g, it's slightly heavier than the standard Phantom 4, but the all-weather capability is the trade-off. Topo's signature roomy toe box promotes natural toe splay for proper running form. At ~NT$5,200, it's a worthwhile investment for those who need to run in wet conditions. Start with easy 3-5km runs.
