After a long hiatus, Nike has released a wide assortment of Nike Air Tech Challenge II colorways in 2014. The latest rendition of one Andre Agassi's most coveted signature sneakers has a color scheme that looks straight from the 90s, but it's completely new. This "Poison Green" model shares the same look as the original "Hot Lava," but with brightly colored green instead. Plus, they also have fresh black and grey accents, splatter details, and OG tongue tag design. Simply a great retro tennis sneaker to add to your collection. You can cop them now at Sneakerhead.
