About this product
Mesh forms the upper of the Under Armour Surge 4 AC TD, giving the shoe a lightweight, open-textured feel and allowing the material to flex naturally. Castlerock/Anthracite combines two muted shades for a restrained look that pairs well with neutral clothing. Released in 2025, the infant 'Castlerock' version brings this subdued palette to the Surge silhouette from Under Armour.
