With an external TPU heel counter and EVA medial post, Ultrafly 3 offers rear-foot stability and light pronation resistance. The cushioned 2-density ZipFoam™ midsole delivers more long-term resilience and a higher rebound compared to traditional EVA. The engineered mesh upper provides a seamless and breathable fit, while a molded foam collar and Ortholite® footbed offer additional comfort. Ultrafly 3 is a perfect daily trainer for those seeking a moderately cushioned ride with light guidance. Like all Topo Athletic shoes, these men's athletic running shoes with wide toe box feature our signature snug heel and roomy toe box fit.
