"Flip the Old School" is a tribute to the 1999 NK Dunk High "City Attack" group. The shoes are mainly white and purple. Although only two colors are used to present this pair of shoes, there are many components, which are very eye-catching. First of all, this fabric is made of very rare ostrich leather with countless protruding particles. The colors of the left and right feet are also completely opposite. What's more noteworthy is that the NK Swoosh on the side of the shoe uses an undercut design. The outside of the shoes will also be covered with special graffiti packaging when purchased, which greatly increases the collection value of this pair of shoes.
