Nike's 'One Luxe' leggings are designed for even the most intense workouts, whether you're lifting weights at the gym or going hard at CrossFit. Designed with a high-rise waistband that won't budge or dig in, this black pair is made from stretch fabric engineered with the label's sweat-wicking Dri-FIT technology. They're sleek enough to wear with a T-shirt when you're running errands at the weekend, too.
