This week, Nike and Kyrie Irving officially introduced the 4-time All-Star's latest signature sneaker, the Kyrie 4. Irving debuted the model in the multicolor "Confetti" colorway Friday night, then followed up with two additional styles on Saturday. It's already been a strong season in sneakers for Irving and things will only get more interesting as the Kyrie 4 story unfolds.

Elsewhere, Clippers big man Montrezl Harrell continues to impress with his vintage stock. Not only is Harrell bringing the heat in every game, but he's pretty much wearing at least two pairs per outing. That's bad news for the equipment manager, but great for #SoleWatch.
