About this product
The 2024 Flow FUTR X 3 ‘Black Sonic Yellow’ brings a fresh colour statement to the Flow FUTR X silhouette. Its IntelliKnit upper uses a knitted construction that generally creates a textured, flexible-looking surface. Black, Sonic Yellow and Castlerock form the colour combination, giving the men’s Under Armour shoe a mix of dark, vivid and muted tones without relying on extra detailing.
