The Air Jordan 21 (XX1) OG released in a Low cut model in July. The model was the Air Jordan 21 (XX1) Original Low White / University Blue - Metallic Silver. When released, this model did not do well in stores, and eventually hit Nike Towns and the price reduced.
Maybe a turn off for many, the Air Jordan 21 (XX1) Original Low White / University Blue - Metallic Silver came in a normal Jordan Box, and not a Jordan XX1 box. Also, they did not have the interchangeable pods (IPS).
