Combining design elements from older models to create a completely new sneaker is a tactic that Nike has used before with varying degrees of success. Yet, it's hard to argue with the outcome of the Nike Air Tech Challenge Hybrid. This new model is a mash-up of a few of Andre Agassi's signature models, which originally hit the tennis courts in the late 80s to early 90s. The "OG" model features familiar vibrant color accents while the "Wimbledon" model sports a toned down white and green colorway. You can score an ace with both pairs at Sneakerhead today.
