TMAC 4 - The TMac 4 is a much sleeker and lighter shoe than before, this reflects his character and the way he plays the game. The heel uses the triple stack technology, three individual carbon fiber plates stacked up to give Tracy a little extra bounce in his step. The upper is capped off with the big strap baring Tracy's logo on top, letting everyone know this is Tracy Mcgrady's shoe. The shoe's overall design has a clean but technical feel to it, the bottom was inspired by racing tires, for its speed and traction.
