Adidas Yeezy Boost 350 V2 'Onyx'
The adidas Yeezy Boost 350 V2 launched in September 2016 as the successor to the original 350, introducing a higher collar, redesigned Primeknit pattern, and the now-iconic lateral SPLY-350 stripe. Designed by Kanye West in partnership with adidas, the 350 V2 became the most commercially successful silhouette in the Yeezy line and one of the most culturally significant sneakers of the 2010s. Its blend of performance Boost cushioning with a fashion-driven design bridged the gap between sportswear and high fashion.
The Onyx colourway commits to a fully blacked-out palette across the entire shoe. The all-black Primeknit upper is complemented by a post-dyed monofilament side stripe that adds a subtle see-through detail without breaking the monochrome finish. Black rope laces, a black TPU-caged midsole, and a black rubber outsole complete the seamless tonal design.
Full-length adidas Boost midsole surrounded by a ribbed semi-translucent TPU cage finished in black for responsive cushioning with structural support. One-piece all-black Primeknit upper that stretches and conforms to the foot for a sock-like, adaptive fit. Post-dyed monofilament side stripe for a clean, minimal design detail. Webbing pull tab at the heel for easy on and off. Durable rubber outsole with a geometric tread pattern for multi-surface grip.
Fit: Runs true to size. We recommend going half a size up for a comfortable fit, as the Primeknit upper fits snugly.

The Yeezy Boost 350 V2 Onyx is for anyone who wants the 350 V2 silhouette in its most wearable, no-fuss form. The all-black colourway removes any styling barriers, making it the go-to Yeezy for daily rotation. It suits those who value understated versatility and genuine Boost comfort over bold colourway statements.
The Onyx 350 V2 is the ultimate everyday Yeezy. The all-black palette means it works with literally any outfit, from joggers and hoodies to tailored trousers and an overcoat. It functions as a neutral base that never clashes, making it the most versatile shoe in the 350 V2 range.
The Onyx is the most popular tonal 350 V2 alongside the Bone and Slate. Compared to the Bred, which uses red SPLY-350 branding for contrast, the Onyx is entirely monochrome with no visible branding, making it the quietest 350 V2 in the range. Its monofilament side stripe places it in the later generation of V2 releases, distinct from the original SPLY-branded colourways like the Zebra and Oreo.
The Yeezy Boost 350 V2 fits snugly due to the stretchy Primeknit upper. We recommend going half a size up from your usual UK size for a more comfortable fit, especially if you have wider feet.
The Onyx features a post-dyed monofilament side stripe instead of the traditional printed SPLY-350 branding. This creates a subtle see-through window on the lateral side that blends seamlessly into the all-black upper, giving the shoe a cleaner, more minimal look than earlier 350 V2 releases.
The Onyx colourway is a unisex release available in UK sizes 4 to 12, covering both men's and women's sizing. Order your usual UK size (half up if between sizes) regardless of gender.
We recommend spot cleaning the Primeknit upper with a soft brush or damp cloth and mild soap. The all-black colourway is the most forgiving in the 350 V2 range when it comes to marks and scuffs. Avoid machine washing and allow them to air dry naturally away from direct heat.
