The NBA Summer League is officially underway, and while it may not draw quite as much attention as the regular season, this list from Sole Collector should give you plenty incentive to check out a game or two. Sole Collector has gathered a group of shots featuring today's top NBA players pre-superstardom in Sneaker Watch Classic // NBA Summer League.

One interesting takeaway from the photos is that most of these players had yet to sign sneaker contracts. Only LeBron James, who had signed his $90 million deal with Nike before the draft, was actually wearing his sponsor's sneakers. You'll see players like Derrick Rose in Nike, Russell Westbrook in adidas, and many more selections that may surprise you. Check out the gallery above for some of the top players, and head over to Sole Collector for the full collection.
