Profile of the Under Armour Project Rock 2

It is the second iteration of the shoe released under the brand’s cooperation with Dwayne Johnson. After the immediate success of the Project Rock 1, Dwayne knew that they needed to take it to the next level with the following version.


The TriBase outsole was first introduced in the brand’s TriBase Reign cross-trainer. Considered a success, it’s been carried over to the PR 2. Apart from protecting the shoe, it also ensures flexibility and ground control. 

The TriBase offers both upward and downward flexibility. The upward one is needed during such agile exercises as running and jumping. As for the downward flexibility, it helps the foot dig into the ground to achieve stability when lifting. 

To help the wearer feel more grounded, the midfoot and heel parts of the outsole were made flat. The absence of lugs makes these areas thinner and closer to the surface. That way, the foot receives better ground feedback and can make micro-adjustments.

The texture of the rubber allows it to grip the gym flooring and avoid slippage. Additional rubber knobs in the forefoot further enhance the shoe’s traction.


The Project Rock 2 has become the first training shoe from Under Armour to incorporate the HOVR technology. Before that, HOVR was only used in the brand’s running footwear. 

This material has proved itself to be an efficient cushioning material which protects the foot from impact and maintains a bouncy feel. These characteristics come particularly helpful during high-impact exercises.

However, HOVR’s softness shouldn’t make you feel concerned about stability. It is crated by a compression mesh called Energy Web and a firm heel carrier. They contain the HOVR within a given shape and do not let it squash under heavy load.


This Under Armour trainer features a low-cut anatomical cleatie construction. It aims to provide a snug and adjustable fit and move as one with the foot. The soft knit fabric has a lightweight nature and is also described as fast-drying.

The 3D-molded midfoot panels add structure to the upper. They work together with the lacing system to reinforce lateral support. That way, the foot stays locked in place throughout the training session.

The mesh pores on the forefoot make sure the foot stays ventilated through the toughest of workouts. In the midfoot section, breathability is ensured by the laser-cut perforations. 

An external heel counter is added at the rearfoot. This sturdy yet lightweight plastic component guarantees heel stability. It boasts of the signature bull logo on the outer side and the “Blood. Sweat. Respect” tagline on the medial side.

Project Rock 2 vs. Project Rock 1

The Project Rock 2, also referred to as PR 2, is a total revamp of the original design. Coming at a $20 higher price tag, it features a number of changes to level up the game:  

- The new TriBase outsole aims to provide flexibility and ground contact in the right areas.

- A soft HOVR midsole encased in the firm Energy Web gives a better balance of stability and responsiveness. 

- The updated upper design is meant to give a more precise fit and enhanced support.

What is Project Rock?

“Project Rock” is a motivational lifestyle brand which was created through the collaboration between Under Armour and Dwayne “The Rock” Johnson. Thus, the items from this collection can be recognized by Dwayne’s signature Brahma Bull logo.

As stated by Johnson himself, “Project Rock recognizes that we are all a work in progress, consistently trying to get better and working harder toward our goals.”

This partnership started in January 2016 and has already resulted in several successful releases. That includes the Project Rock 1 shoe which was sold out within the first 24 hours after its launch.

The Project Rock collection includes not only footwear, but also workout apparel, bags, and even wireless headphones.
