The New Balance X90 "Mustard Yellow" gets an overhaul with an all-new colorway. Introduced in 2018, New Balance presented a streamlined design that incorporates classic looks into a modern construction. The silhouette is crafted with a slip-on design in mesh and leather materials with reflective branding, and a REVlite sole unit provides lightweight cushioning underneath. Mustard yellow and grey come together to coat the sneaker's upper, while the shoe is finished off with a white midsole and black outsole.
