To encourage greater responsiveness, the Vapor X Knit has a tighter fit than the Vapor 9.5. If you prefer a little extra room in the toe box, our playtesters recommend going up a half-size.

The Nike Women`s Air Zoom Vapor X Knit Tennis Shoes take breathable performance to the next level. These dynamic shoes feature many of the same great technologies you know and love from traditional Vapor Xs, but introduce an innovative, redesigned upper for greater support and response during your most explosive movements. 

Upper: Circular-knit material is breathable and lightweight, but offers high-tensile strength for support. The Dynamic Fit system is integrated into the upper for a more adaptive fit. A stretchy internal sleeve further enhances support and response. Small polymer triangles increase durability around the toe and medial forefoot.

Midsole: The Vapor X Knit utilizes a soft foam midsole with a Zoom Air unit in the heel for low-profile, responsive cushioning.

Outsole: Nike XDR is arranged in a pattern ideal for hard-court surfaces. The full-length foot frame helps stabilize your foot during quick cuts, while flex grooves let your foot move naturally.

Color: Light Smoke Grey with Pink Blast, Grey Fog and White
