The Brooks Women's Dyad 10 is perfect for unique feet with a lighter roomier fit. This running shoe sports a generous fit for flat or voluminous feet. Brooks’ BioMoGo DNA, their proprietary cushioning, adapts to your stride, weight and speed. Why? So it can protect you by deflecting impact away from your body. Innovative arch support that we call Dual Arch Pods, together with a wide platform, provide stability without getting in the way of a neutral stride.
