The Nike Kobe A.D. Mid “Optimism” Mamba Mentality Pack will release in five colorways which comes in Grey, Blue, Purple, Red and Yellow. The Grey pair represents calm neutrality. Blue relays dependability and trust. Bryant equates those traits with honesty. Yellow and positivity go hand in hand, or as some say, “amongst the clouds there is always the sun.” Red is acknowledged as a symbol of passion while Purple represents overcoming challenges and setting fresh goals.
