The Undefeated x Kobe 4 Protro 'Devin Booker' was introduced in August 2019 alongside three other colorways. This particular iteration of the low-top sneaker showcases an orange color scheme with purple accents, paying homage to Devin Booker's team, the Phoenix Suns. The sneaker prominently displays branding for both Kobe Bryant and Undefeated on the tongues and sockliner. The combination of a patent leather upper and Flywire panels creates a seamless look. Additionally, the back heel of the shoe features both of Kobe's iconic jersey numbers, 8 and 24.
