The Undefeated x Nike Kobe 4 Protro “Black Mamba” is an ultra-stealthy collaborative release between the LA-based streetwear boutique and Nike Basketball on Kobe Bryant’s fourth signature Nike shoe. The all-black “Black Mamba” Undefeated x Nike Kobe 4 Protro is the fifth colorway of the series of Kobe 4 releases centered around Nike Basketball’s celebratory “Mamba Day” that honors the career and legacy of Kobe Bryant. The upper is comprised of an oily-looking iridescent finish as a nod to Kobe’s venomous nickname. A tonal black Swoosh with white outlining is located on the mid-panel with co-branding appearing on the tongues. Further detailing includes the numbers “8” and “24” covering the heel with subtle Undefeated branding appearing below. A white rubber midsole and a black forefoot put the finishing touches on the classic design. The Undefeated x Nike Kobe 4 Protro “Black Mamba” was released on September 13th, 2019.
