Who should not buy the Under Armour Project Rock 4

Workout enthusiasts with broad feet might want to think twice before grabbing a pair of the Under Armour Project Rock 4. Its tight opening and the narrowness of its midfoot area might only disappoint them. They are better off with the Under Armour Charged Commit TR 3.

Changes to the Under Armour 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.
