Since their launch in 2001, the 991s have been synonymous with exceptional quality. As the first 99X model of the 21st century, the original 991s set the standard for modern running shoe design. The Made in UK 991v2 represents a new pinnacle, bringing an evolutionary reinterpretation of this true icon. A streamlined reimagining of the classic upper made from pigskin suede, mesh, and synthetic materials offers a sleeker profile while maintaining a familiar look. The most significant technological change is the addition of Full-Length FuelCell cushioning. This update reflects the updated approach to the upper while pairing the revamped structure with classic features such as ABZORB SBS capsules and ENCAP cushioning.
