The Yeezy Boost 350 V2 ‘Tail Light’ gets its name from the vibrant hit at the heel. The shoe’s Primeknit upper features a largely neutral look, finished in grey and complemented by a monofilament stripe. However, the shoe’s heel pull-loop adds color to the look in red. Underfoot, the semitranslucent rubber midsole includes a full-length Boost midsole for cushioning.
