Ultrafly 4 Running Shoe – Women's

Built for road runners who want a little guidance without the stiffness of a traditional stability shoe, the Ultrafly 4 is our top pick for daily training miles. A dual-density ZipFoam midsole delivers more spring and energy return than standard EVA, while a wide anatomical toe box lets your foot move the way it's built to.

• Dual-density ZipFoam midsole returns more energy than standard EVA foam — responsive underfoot without feeling stiff or dead after long miles
• Medial post and external TPU heel counter offer light pronation control and heel guidance without the bulk or rigidity of a full motion-control shoe
• Wide anatomical toe box gives your toes room to spread and splay naturally — especially welcome on longer runs when feet tend to swell
• 28mm heel / 23mm forefoot stack with a 5mm drop keeps you close to the ground while providing enough cushion for road and light mixed-surface training
• Recycled engineered mesh upper wraps the foot securely while staying breathable — a real advantage during long runs in Southern heat and humidity
