The Yeezy Boost 350 V2 “MX Oat” is an intriguing look for the popular lifestyle shoe by Kanye West that features an all-marbled upper. Released in October 2021, the “MX Oat” blends red, blue, orange, and yellow swirls on a beige, oat-colored Primeknit base. The look is a departure from the traditional layered look of the original Yeezy Boost 350 V2. This was the very first "MX" or "Mix" variation of the silhouette to release. Like many 350 V2s, a side monofilament side stripe compliments the colorway. White laces contrast the colorway on the top of the shoe. Underfoot, the ribbed midsole that houses yeezy’s Boost cushioning technology appears in a pre-yellowed vibe. Release date: October 23, 2021
