The Jordan 6 Ring Shoe is a combination of the six Jordan shoes Michael Jordan wore in the final NBA championships he was in. The shoe is a combination of shoe numbers 6, 8, 11, 12, 13, and 14 that correspond to championship years '91, '93, '96, '97, '98, and '99. Arguably, the most popular shoe of these was the #11 or #12 Jordan shoes.
Here are a few pictures from various places on the web of the Jordan 6 ring shoe, in different colors.
This shoe is the culmination and celebration not only of the Air Jordan brand, but also of the player Michael Jordan and his influence on the American culture. Perhaps the greatest measure of this is the popularity of this shoe as it's designed to commerate each of the championships Michael Jordan played in during his basketball career.
If it was my choice, I would most likely choose the red and black version, as that was the original color of the Jordan shoes line.
