Starting at the toe, the toe cap has Jordan's signature embossed. The side of the shoe features a stitched pattern that gives the shoes strength in addition to cosmetic effect. The tongue of the left and right are different for a first time with a jumpman logo on the right shoe and the number "23" embedded on the left shoe. The shoe also features a glittery glossy panel that covers the midsole body of the sneaker. This was the first Air Jordan that was engineered to not use any glue. According to an article in Jet magazine, the XX3/XXIII is the first basketball shoe to be made under the "Considered" ethos, meaning the shoe is made with the environment in mind. The shoe was constructed using the absolute minimum amount of adhesive to make it more environmentally sound, while the soles (which are designed from Jordan's own fingerprint) are made from recycled rubber. It is considered the most technologically advanced Jordan model to date, and according to Gentry Humphrey, the head of the Jordan design team, it may be the last actual Air Jordan. The shoe was released in three different colorways from January to February, with a limited edition release where 23 retailers around the world sold the shoe, before its national release in February. The Air Jordan XX3/XXIII model had virtually eliminated the Jumpman logo. It is found only on the tongue of the right sneaker, and completely missing on the left sneaker, except on the ends of the shoelaces.
