Women's Structure 20

The Structure has found a home in the “run fast” silo—maybe not a place you’d expect to find a stability shoe. When you need support, it uses a slanted block of foam that angles higher toward the medial (inner) edge of the shoe and is fused in the molding process to a softer foam that makes up the rest of the shoe. That compression-molding eliminates glues and other joining materials that can make a shoe stiff. A Zoom Air unit in the forefoot provides a firm platform during toe-off.
