The Topo Athletic Phantom 2 is built to take on your long runs, daily training, and recovery runs, delivering the comfort of its predecessor, now with even more cushioning and response. The overlay-free engineered mesh upper made of 30% recycled materials keeps the foot cool and comfortable, with reinforced security through the midfoot. With a 3 mm higher stack height, the updated midsole features a ZipFoam™ core for a snappy, yet soft feel underfoot. The external TPU heel counter integrates with the midsole to keep the foot seated over the platform for a secure and stable ride.
