Featuring a Cushlon foam for increased comfort during high-intensity cardio, the Nike Metcon 9 women's training shoes are ideal for indoor training. The outer rubber wraps up your arch for optimal grip and the tread adds traction from the gym floor to the pavement. The wide, flat and flexible heel provides stability to your intervals thanks to the inner plate that distributes weight from edge to edge while the handstand clip minimizes drag during wall exercises. This version of Metcon comes with a lightweight mesh and textured overlays to help keep your foot cool without sacrificing durability.
