The 7 was originally a low, but Nike and Bryant gave consumers options with replaceable inserts with sleeved uppers to provide ankle support. The inserts were equipped with cushion foam and Zoom Air. The 7 also came in an Elite version, making it the first in a Kobe signature shoe. The distinctions from the regular and Elite versions were most notable in the heel. The regular model featured a clear piece of Thermal Plastic Urethane (TPU) whereas the Elite version featured a real piece of carbon fiber. The 7s campaign also featured the famous “Kobe System” commercials with Kanye West and Serena Williams.
