The fifth-generation Ultrafly blends Topo’s distinctive foot-shaped comfort with refined stability and enhanced cushioning, making it an ideal option for runners seeking moderate pronation support in a lightweight trainer. Designed with a purposeful 30 mm heel / 25 mm forefoot stack, the Ultrafly 5 gains 2 mm of additional foam underfoot for extra shock absorption and comfort without compromising ground feel or control.
The ZipFoam™ midsole provides a dual-density platform that’s softer against the foot for comfort and firmer at ground level for a responsive, energy-efficient ride. A subtle medial post and external TPU heel counter offer structured support for mild overpronators, guiding the foot naturally through the gait cycle without stiffness. The OrthoLite® Performance Insole contributes to step-in softness and long-lasting breathability, while the redesigned upper—made from recycled engineered mesh—delivers lightweight structure and zonal ventilation across key areas.
True to Topo’s design philosophy, the anatomical toe box encourages toe splay for balance and comfort during long miles. Whether you're logging daily runs, training for a half marathon, or looking for a walking shoe with thoughtful support, the Ultrafly 5 delivers dependable comfort with a performance edge.
