The New Balance 990 is one of the greatest sneaker lines ever. First released in 1982, the original took four years to develop and cost around $100—a lot for a running shoe back then. But the Boston brand wanted to make the best one it possibly could, and it wasn’t cutting corners. More than four decades later, the series has given us some of its best trainers, with each generation making its own adjustments to the suede, the mesh, and everything underfoot.
