For fall/winter, Andre Agassi's popular Air Tech Challenge II takes a walk on the dark side. The vintage tennis sneaker, which is typically decked out in a white leather, has been updated with a black suede base and deep blue paneling. It's a few shades off from being a murdered-out colorway, but it's certainly close.

There's also some interesting texture going on throughout the sneaker, giving the ATCII a luxe feel. A scaly pattern takes over the Swoosh and paneling along the toebox, while a ballistic nylon covers part of the side panels and heel.

No word yet on a U.S. drop date, but you can already find these overseas at select Nike Sportswear retailers, like End Clothing.
