Despite a handful of releases and restocks, The Rock's Under Armour Project Rock Delta trainers haven't exactly been easy to come by, but fans of the actor can pick up a new batch of "Chase Greatness" colorways beginning today.

This three-sneaker lineup includes "Steel/Black," "Steeltown Gold/Black," and "White/Black" colorways of The Rock's signature shoe. The high-top trainers use a seamless mesh upper with a two-piece Charged midsole setup that combines soft and dense foams for a balanced cushioning.

See The Rock put the shoes through the rigors of the weight room in the clip above and pick up a pair of the Project Rock Deltas while they last from underarmour.com for $140.
