Taking inspiration from Jimmy Butler's love of tennis, the JB2 is more sleek and more plump. The latest color is Home Jersey colorways for Miami Heat. The basketball sneakers are dressed up with white base accented with Miami Heat red and black detail throughout for contrast. His JB logo can be spotted on shoes tongue and heel. For the perfomance, Li Ning added latest Li Ning Boom, Boom Fiber and GCU(Groud Control Unit) on the shoes. What is more, Li Ning upgraded Carbon Fiber plate on midsole to mixed with Boom materials, which is first li-ning shoes with that tech.
