Brand new with box. 100% Authentic! Like the Nike Air Max Sequent 4, the rubber outsole is integrated into the Nike Air Max Sequent 4.5 as well. This one-piece outsole provides excellent protection when tackling different paved surfaces. It also delivers long-lasting efficiency against the possibility of wear and tear. Along with the rubber material is the updated outsole pattern. Nike added this feature to provide more flexibility without sacrificing the running shoe's durability. As a result, a more natural foot movement and smoother ride are experienced by the user.
