About this product
The Under Armour Surge silhouette gives this pair its model identity, paired here with the Castlerock/Red colourway. The combination balances a subdued grey tone with red for a distinct contrast. This Surge 4 arrived in 2024, carrying a straightforward colour arrangement that keeps the focus on the two named shades. Its design stays closely tied to the Surge name and the simple, contrasting palette.
