The Yeezy Boost 380 “Blue Oat Reflective” is the alternate “Blue Oat” colorway with reflective detailing. The Yeezy Boost 380 was originally tabbed as the predecessor of the Yeezy Boost 350 V2, but was later renamed by yeezy and is every bit as stylish as the shoe it parallels. Reflective detailing that shines when exposed to light is incorporated into the bold orange Primeknit upper, differing from the non-reflective “Blue Oat” variant. Additional styling cues include a contrasting blue stripe on the midfoot, brown detailing in a camo-like pattern throughout the upper, and cream or “Oat” laces. Boost cushioning is encased within the light brown midsole for a responsive step-in. The look is finished off with a gum rubber outsole. Release date: July 24, 2020.
