The Nike Air Tech Challenge II Black Lava was made available as a partial motivation for the culture-switching Air Yeezy 2. The sneaker comes in a Black/Hot Lava-White-Granite colorway. The upper features midfoot and forefoot crafted from white leather, while the rear and front mudguard pieces adorn signature speckled lava schemes. More lava spreads over the collar’s liner, complemented by black leather with grey detailing and white overlays. A grey and white rubber sole appears at the lower part, with 'Nike Air' branding on the insole, heel, and tongue. The shoe showcases Hot Lava Swoosh logos. The Air Tech Challenge 2 QS 'Black Lava' brings back the iconic ‘90s tennis shoe made famous by Andre Agassi, flipping the black and white color blocking of the OG colorway. The leather upper is predominantly finished in black with microperforated detailing, and the leather Swoosh in Hot Lava is carried over from the original release alongside signature paint splatter effects.
