Changes to the Project Rock 4

The UA-backed enterprise of Dwayne "The Rock" Johnson has released another collection, including the fourth iteration of the famous Project Rock training shoes. But what exactly sets the Project Rock 4 from the previous version?

Aside from the noticeable TPU strap, the shoe looks precisely the same from the outside. Hence, it's no one's fault if they interchange Project Rock 3 and 4. The following are the feature trainer's updates and similarities with its predecessor:


  • A sock-like mesh upper for the same breathability
  • Responsive cushioning and comfort brought by the HOVR foam technology
  • Abundantly foamed collars to prevent rubbing and chafing
  • Excellent ground feel and uber-stable base, care of the TriBase outsole


  • Additional midfoot strap for lateral support and stability
  • TPU heel clip acts as a heel stabilizer to keep you surefooted during squats, weightlifting, and fast-changing movements.

Who and what is it for?

The Under Armour Project Rock 4 is a training shoe recommended for the following individuals:

  • Fans of the Project Rock shoe series
  • Fitness enthusiasts who like to dabble in both explosive cardio exercises and weightlifting
