Men's Ultrafly 6

The Topo Men’s Ultrafly 6 is built for runners who want high cushioning with smooth, unobtrusive stability for daily miles. Updated from top to bottom, this version features increased cushioning and a redesigned medial post that now wraps the heel, creating a more seamless stability experience through the gait cycle. The result is guided support that feels natural, not rigid. The evolved ZipFoam™ midsole delivers a lively, resilient ride that maintains rebound longer than traditional EVA. With a 32mm heel / 27mm forefoot stack height and a 5mm heel-to-toe drop, the Ultrafly 6 promotes a balanced, efficient transition from heel strike to toe-off. Weighing 9.6 oz (Men’s size 9), it offers high cushioning without sacrificing responsiveness. Additional rubber coverage on the outsole enhances durability and traction while reinforcing the shoe’s inherent stability platform. A lightweight, breathable upper provides a secure “second skin” fit, and Topo’s anatomical toe box allows natural toe splay for improved alignment and comfort over long training runs.
