In this case, NIB means ‘new in bag’ because I stored them in a ziplock bag to save room & I don’t have the box anymore. Cole Haan collaborated with Nike to make heels more comfortable. Google the reviews on this shoe design -the collaboration was really popular -& expensive. Nike Air sneaker technology was incorporated into the shoe platform for cushioning & support. These wedding shoes with a 3 1/2 inch heel, a half inch platform & an adjustable ankle strap (that is removable so you could replace it with ribbons) are also dyeable satin. So you can wear these white or you can have them dyed at your cleaners any color you like. You could even have an artist paint watercolors on them. Nonsmoking home.
