Nike is releasing a trilogy of Bo Jackson edition Dunks that resemble other Nike models previously worn by the two-sport athlete. This Dunk High Premium is part of that trilogy. Bo Jackson, the 1985 Heisman Trophy winner, was a Nike icon ("Bo Knows.") and a symbol of cross training in the late 80s/early 90s. Coined the "Medicine Balls" on many popular sneaker forums, this Dunk was inspired by the Nike Trainer III.
