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. DETAILS Roomy toe box helps toes align in their natural position for better balance, stability, and comfort. Secure midfoot and heel so you feel nimble, agile and secure no matter the terrain. Low heel to toe drop encourages a midfoot strike when running so you move naturally through the gait cycle.
