Turns out the intersection of sport and glam is a pair of adidas track pants. Made with a touch of satin that steals the show, these must-haves are casual enough for lounging but can take on a night out, too. Speaking of that, side zip pockets keep your essentials close, and an elastic waist gives you room to move. Snap-button side panels nod to classic '90s warm-up pants, sporting athletic edge made for today.
