Even though the Nike Air Tech Challenge II "Turbo Green" just barely hit U.S. retailers this week, we can already expect the next drop from this classic tennis line. Perfect for spring, the "Kumquat" colorway will start to hit Nike Sportswear retailers like Crooked Tongues starting next month.

This Air Tech Challenge II features a neutral white/off-white leather upper with kumquat orange accents for a nice pop of color. Word to Andre Agassi. Make room in your growing Air Tech Challenge II collection for this one when it drops in May.
