These are the infamous "loon's." They were originally produced in 2004 and were never released. That is, until 2010. However, this is the original sample version from 2004. They were originally made for the Midwest. Nike's Midwest rep, Rob Sissi, is from Minnesota and he chose their state bird, the Loon as inspiration. This is where the feather pattern and green color comes from. These have been one of the most coveted SB's to date. In 2010 they were finally released, but with slight differences.
