The Rock’s Under Armour Training Shoes Are Officially One of 2017's Best Pairs JD May 7, 2017 men health 78 Photograph by Under Armour People are smelling what Dwayne Johnson is cooking If you’re one of the lucky few who managed to score a pair of the pure-flames Project Rock Delta training shoes from Under Armour, you now have your hands on a collector’s item. (Check out the collection here.) Under Armour is claiming the shoe as their fastest-selling in 2017. The initial stock sold out within hours, and the rapid re-stock from UA also sold out, taking the entire slate of Rock Deltas off the shelves in less than 24 hours. The Rock himself took to Instagram to celebrate the occasion and tease a new colorway and more “innovation” of the shoe coming in the fall of this year. His caption read, in its entirety: “#RockDelta Sold out in 24hrs. Appreciate y’all so much for making our first #ProjectRock @underarmour launch into “the shoe business” historic & impactful. We’re working hard on new color ways and innovation for our next #RockDelta drop this fall. I want to make one of, if not the greatest training shoe you’ve ever worked out in. Much more work to be done. Thanks again, stay strong and enjoy the shoe. #RockDelta #ProjectRock#UnderArmour Next drop FALL 2017.” No word yet on what that innovation might be, but if the Rock’s recent run of striking gold is any indication, we can only expect more hot commodities to come out of his camp as the season turns. There is officially a run on Steph Curry’s money.
