About the Nike Kobe 11 Protro Low 'Mamba Day'

The Nike Kobe 11 Protro Low 'Mamba Day' celebrates the tenth anniversary of Kobe Bryant's final NBA game. The low-top carries a black mesh upper that's covered in metallic gold numerology references, including the dates of Kobe's first and final NBA games, along with references to his five titles and 81-point game. This Protro edition features a drop-in ReactX foam midsole with Zoom Air cushioning in the heel. Underfoot, a translucent rubber outsole utilizes a revised traction pattern for optimal grip.
