Thank you for looking. These are Nike Nylon Cortez. The Cortez was the first sneaker released by the Nike brand when it was founded 53 years ago in 1972. I purchased them myself in 1976 and wore them in the gymnasium for about 2 years. After that, I wore them outdoors for about 6 months in 1993. Since then, they have been stored at home in a closet. At one point, while shopping in Amerikamura in Minami, the manager of a general store offered to buy them from me for 120,000 yen. I was scared because I knew nothing about vintage items, so I kept them carefully stored at home. I have not cleaned them for this listing. They are still in a condition where you could wear them around town if you wanted to, but since they are 49 years old, I would appreciate it if you would consider purchasing them for collection or display purposes rather than for use. * I have forgotten the size, but I usually wear a 27cm, so I am confident it is correct. * This blue and silver colorway is a rare model. Also, the type with integrated reinforcement rubber on the heel is a rare item. Please consider these if you understand vintage sneakers, have been looking for them, or like them. * Please check the images, and refrain from purchasing if you have any concerns, however small. * These are home-stored items. We kindly ask that only those who understand and acknowledge that these are used items purchase them. Please refrain from price negotiations.
