One of the sneakers that Bradley Beal wore in the 2014-15 season is the Nike Lunar Hyperquickness.
This budget basketball shoe utilized standard Phylon foam and Zoom Air cushioning in the forefoot. Combined the soft midsole gives an extra bouncy sensation on forefoot strikes. Hyperfuse plastic is used on the upper for durability and breathability.
