Per J. crew: In 2013, we designed the be-all end-all of ballet flats, a timeless shoe that everyone should have in their closet. This year, we brought them back in new colors, prints and fabrics as part of the Reissues, a collection of iconic best-sellers, updated for a new decade. We took the same silhouette—a classic ballet flat with a tapered toe and a tiny heel—and added an extra-comfortable footbed. Satin upper. Leather lining. Man-made sole.
