TOPO ATHLETIC's Ultrafly 3 delivers a smooth and comfortable ride with light guidance for daily training. The moderately cushioned platform features a 2-density midsole with ZipFoam™ for more long-term resilience and a higher rebound than traditional EVA. The external TPU heel counter and EVA medial post offer rear-foot stability and light pronation resistance. The engineered mesh upper provides a seamless and breathable fit, while the molded foam collar and Ortholite® footbed offer additional comfort.
