Since its original release in 2001, the 991 has been synonymous with superlative quality. As the first 99X model of the 21st century, the original 991 set the standard for modern running design. The MADE in UK 991v2 represents a new pinnacle, with an evolved take on this genuine icon. A streamlined take on a classic pigskin suede, mesh, and synthetic upper offers a sleeker overall profile, while retaining a familiar look.
