The Undefeated x Kobe 4 Protro 'Fir' launched in August 2019 as part of a four-piece collaboration celebrating Mamba Day. This pair applies dark green coloring on an upper constructed from a blend of patent leather and Flywire-infused synthetic, all mounted atop a solid off-white midsole. Unique branding hits include Undefeated’s logo printed on the heel, along with the retailer’s five strikes logo atop the left tongue.
