Air Force 1 Supreme I/O 'K-Dice Dragon'

The Nike Air Force 1 Supreme I/O 'K-Dice Dragon' sneaker is the result of a 2008 collaboration between the Swoosh brand and Japanese baseball player Daisuke Matsuzaka. Matsuzaka's shoe features a unique combination of materials, with pony hair and snake-inspired leather dressing the classic style. The shoe retains signature details to honor the player, including a dragon insole emblem in the shape of the number '18'—the number Matsuzaka wears while pitching for the Boston Red Sox.
