The Under Armour Project Rock 3 White Halo Grey is a dynamic training sneaker that is part of the Project Rock Collection, a partnership with Dwayne ‘The Rock’ Johnson. At first, the sneaker looks like it has an all-white construction, but on further inspection, you can find Halo Gray details. For example, the bullhead detail on the side panel and the grid-like texture across the midsole come in Halo Gray. The sneaker boasts a knit upper made of a lightweight material that allows the foot to breathe. It also has a bootie-like fit, which helps the material to conform to the foot’s shape. In the midsole, UA HOVR technology provides responsive cushioning without adding bulk to the sneaker. In addition, UA TriBase technology increases flexibility in the forefoot that supports dynamic movements. The Under Armour Project Rock 3 White Halo Gray was released on July 19th, 2021, and retailed at $140.
