The Topo Athletic Women’s Ultrafly 6 Running Shoes in Grey/Sky deliver the perfect blend of plush cushioning, lightweight stability, and natural comfort for runners and walkers seeking reliable support without sacrificing responsiveness. Completely refreshed from top to bottom, the Ultrafly 6 builds on the trusted foundation of previous versions with more cushioning, smoother stability, and an even more energetic ride.
The versatile Grey/Sky colorway combines soft neutral tones with cool blue accents for a clean, modern running shoe style that transitions effortlessly from workouts to everyday wear.
At the core of the Ultrafly 6 is Topo Athletic’s upgraded ZipFoam™ midsole, engineered to provide a lighter, softer, and more responsive underfoot experience. This proprietary cushioning system delivers long-lasting rebound and plush comfort while maintaining the balanced feel runners love for daily miles and walking.
Designed for runners who want support without bulk, the Ultrafly 6 features a redesigned medial support post that now wraps around the heel to create smoother, more natural stability throughout the gait cycle. The result is a stable yet unobtrusive ride ideal for daily training and long hours on your feet.
The shoe’s multi-density midsole construction combines softer cushioning closer to the foot with a firmer, more responsive layer near the ground for an ideal balance of comfort and support.
With a 32mm heel / 27mm forefoot stack height and a smooth 5mm heel-to-toe drop, the Ultrafly 6 promotes natural movement while still delivering generous cushioning for road running and walking.
Topo’s signature anatomical roomy toe box allows toes to spread naturally, enhancing comfort, stability, and foot function during longer efforts and all-day wear.
The lightweight breathable upper creates a “second skin” fit and feel, helping keep feet cool and comfortable while maintaining secure lockdown through every stride.
Underfoot, additional rubber coverage on the outsole improves durability, traction, and overall stability across road surfaces.
Recognized with the APMA Seal of Acceptance, the Ultrafly 6 is designed to support healthy foot function and long-term comfort.
Whether you're logging daily training miles, walking for fitness, or looking for supportive everyday comfort, the Topo Athletic Ultrafly 6 delivers the ideal combination of lightweight stability, plush cushioning, and natural movement.
