The lightest Alphafly we've made so far features a ZoomX midsole for shock absorption upon foot contact with the ground, as well as Air Zoom units for energy return. The wider Flyplate surface made of carbon fiber ensures stable footing with a sense of propulsion, while the midsole and outsole are now fully connected for better transition from heel to toe.
"You wear it and feel like it gives you speed. It's light and comfortable, offering a high responsiveness I've never felt before."
