About this product
Black and white make up the colour combination on the Under Armour Project Rock 4, set against a mesh upper. Designed originally by Dwayne Johnson, this youth-sized version was released in 2021. Mesh is a woven material with an open texture, giving the shoe a visibly different surface from smooth finishes. The contrast between black and white keeps the palette clear and graphic, while the Project Rock 4 name connects this pair to the silhouette created by Johnson.
