The Air Jordan XX3 (Jordan 23) is a ground breaking shoe like many of the other Air Jordans. MJ and JB took strides forward with sustainability producing the shoe without the use of any glue - the first of its kind for a performance basketball shoe. This was accomplished with complex and fine tuned engineering from none other than Tinker Hatfield. The stitching on the side of the shoe adds strength to the shoe, but also makes it much harder to bootleg - something else that JB took into consideration when making these shoes.
