Buy Nike GO FlyEase 。Nike Go FlyEase ‘Volt Celestine Blue’ Sneakers Size: Men’s 8/ Women’s 9.5 Color: White/Celestine Blue/Summit White/Black/Volt NIB The Nike Go FlyEase ‘Volt Celestine Blue’ showcases pastel hues on a revolutionary sneaker that introduces hands-free functionality as part of the brand’s easy-entry FlyEase initiative. The sneaker’s defining feature is the bi-stable hinge, which works in tandem with a midsole tensioner to keep the shoe secure in its fully open and closed states. When open, the insole is raised at an angle that allows the foot to intuitively slide in while pressing down, collapsing the midsole and locking it in place.
