I used to believe that one pair of running shoes could handle all of my gym sessions, but after getting more into HIIT workouts, I realized I need a more stable shoe. Reebok designed these for that exact purpose and the difference feels really tangible—they're stable enough to handle an intense lifting session but flexible enough to transition to a quick Peloton ride or boxing class. Plus, they look cool enough that I don't mind wearing them around the office. —Macaela MacKenzie, senior health editor $90, Reebok. Get it now!
