Regarded as a cultural phenomenon . the adidas Yeezy Boost 350 silhouette generated a cult following when it was initially released in 2015. This 'Glow' makeover—released in May 2019—equips the Primeknit upper with a high-visibility treatment and a translucent stripe to the lateral profile. Integrated lacing and a coordinating heel pull provide easy on/off. Underfoot . the signature full-length Boost midsole looks to the future with a bright glow in the dark finish.
