Why Air Jordan 1 Switch was not released in USA

When Many Air Jordan fans came across the idea of switching the Air Jordan 1 to a low by zipping off the top of the shoes, They instantly fell in love with the shoe. 

 

Unfortunately the shoe was only released outside of USA and there is a reason for that. We have our suspicion that Nike would have infringed on a patent for Fini Classic owned by Fini Brand pictured below.
