The Air Jordan 20 (XX) Original (OG) - White / Black - Varsity Red were released on April 9, 2005, and retailed for $175. They feature a white and black upper, with black patent leather on the to, heel area and ankle strap. The red inner lining is constructed from some sort of velvet material. The design on the midfoot strap is modeled after the trumpets. Hatfield had visited with master trumpet maker David Monette. Monette's presentation trumpets are beautiful and expensive musical instruments that had elaborate cut-outs and engravings. Nike's laser expert, Mark Smith, was brought in to design the midfoot strap. The final design is a complex tapestry of symbols representing MJ's experiences and stories. Each symbol is a cryptic puzzle that only die-hard Jordan fans can deduce.The XX is truly unique, in that it has a revolutionary cushioning technology called Independent Podular Suspension (IPS) system, as well as a free - floating ankle strap.
