The best choice for budget-conscious beginners who need stability. The Ultrafly 5 is the previous-generation stability shoe from Topo Athletic, featuring ZipFoam™ supercritical foam (30mm heel/25mm forefoot) with medial TPU support and a heel counter — providing ample stability guidance for mild overpronation. At 281g, weight is standard for the category. Topo's roomy toe box allows natural toe splay, and the 5mm drop encourages midfoot landing. At ~NT$4,000 — NT$800 less than the Ultrafly 6 — it's an unbeatable value for entering the stability shoe category. Start with easy 3-5km runs.
The Topo Athletic Ultrafly 5 is the brand's stability-support daily trainer, refining the midfoot support structure of its predecessor to give runners needing mild overpronation control a more reassuring option. It features a ZipFoam™ supercritical foam midsole for soft yet stable cushioning that resists fatigue over long training sessions. Support is built into the medial midfoot, providing the stability needed without sacrificing comfort. The upper uses breathable engineered mesh with a comfortable fit suited to prolonged wear. Topo Athletic's signature wide toe box lets toes splay naturally, reducing pressure. At around 281g it is a reasonable weight for a support trainer. It suits daily training, long-distance work and recovery runs, and is recommended for runners who prefer gentle support or who are on their feet for long periods — especially those who like a natural gait but occasionally need extra stability.
