Unveiled in September 2019, the Undefeated x Nike Kobe 4 Protro 'Black Mamba' is an homage to Bryant's on-court alias symbolizing his aggressive game. The special edition is equipped with a black synthetic upper, molded external heel and an iridescent forefoot. Bryant's logo and the brand's five-strike emblem alternate on the tongues and insoles, with jersey numbers at the rear. A semi-translucent outsole sits under the sculpted midsole.
