Nike's running heritage is older than the brand itself, dating back to the days when Blue Ribbon Sports catered to an up-and-coming crowd of serious runners. Inspired by original design from the '70s running boom era, this Daybreak gives a nod to the sneaker's everlasting appeal by lightly stuffing premium leather for a puffy look. And the vintage Waffle outsole? The day would't break without it. Benefits * The foam midsole offers lightweight, super-plush cushioning. * The rubber Waffle outsole, inspired by the '79 original, adds traction, durability and heritage style.
