About the New Balance Fresh Foam X 860v15 'Grey Matter'

The New Balance Fresh Foam X 860v15 'Grey Matter' presents a performance running shoe designed for prolonged comfort. A subdued light grey finish is applied to the engineered mesh upper, accented with a tonal 'N' logo on the quarter panel. Atop the tongue, 'NB 860' branding in bright orange disrupts the neutral color scheme. The lightweight build is mounted on a high-stack Fresh Foam X midsole, featuring New Balance's Stability Plane for added support and stability.
