Just a few minutes we posted an OG / Retro comparison of the Nike Air Tech Challenge. These shoes don’t release for several more months in the States, but they have released in Agassi’s wife’s home country of Germany. They also have the other OG color of White/Violet color. If you want to get them now, you can pick them up for 119,90 € (~$155 USD) at Overkill.Â
