"ZoomX has exceeded our expectations. I've been a part of almost every major innovation at NIKE, and I can confidently say the 4% is among the most significant performance advancements in our history. And this summer, ZoomX will be even more accessible through our celebrated Pegasus, with a new shoe called the Peg Turbo that will join the ZoomX Pegasus 35."
Trevor Evans Nike Prez
"In running, we are seeing brand heat through the running revolution that Mark mentioned. The performance story of Q2 was the incredible impact of the Zoom Vaporfly 4% and the impact it had in the marketplace, as it dominated the podium at the top six marathons this fall. The energy around the Vaporfly 4% and the ZoomX cushioning has a real impact on the rest of our running business. It shows how truly breakthrough performance product drives distinction and creates demand in the market.
