The New Balance WRPD Runner 'Grey Day' dresses the retro-futurist silhouette in a neutral grey finish, crafted from open-cell mesh with suede overlays and an oversized 'N' logo on the quarter panel. Lightweight cushioning arrives via a bulky FuelCell foam midsole, fitted with a medial stability post for improved motion control. Underfoot, a rubber outsole features a wavy traction pattern for superior grip.
