Reebok Harmony Road 2 uses mono-air mesh for breathability. A seamless SmoothFuse upper provides an irritation-free fit, and reflective details improve low-light visibility. Kooshride TPU foam and a lite stride sockliner cushion each step, while a trizone midsole absorbs shock. A pwrzone forefoot design promotes efficiency, and the 10 mm drop gives a full-height feel.
