The adidas Yeezy Boost 350 V2 'Israfil' features a patchwork-like composition on the Primeknit upper . constructed from a two-tone blend of tan and grey yarns. The neutral hues are enlivened by a streak of yellow on the signature post-dyed monofilament side stripe. Responsive cushioning comes courtesy of the standard full-length Boost midsole . encased in a semi-translucent rubber sidewall. A grippy gum rubber outsole provides durable traction underfoot.
