adidas Yeezy Boost 350 V2 'Onyx': The All-Black 350 V2 Guide

The adidas Yeezy Boost 350 V2 'Onyx' (style HQ4540) is the 350 V2 taken down to a single shade: black Primeknit, black laces, a black pull tab and a black-tinted sole with full-length Boost underneath. It first arrived on 20 June 2022, and it is the pair for anyone who wants the 350 V2 shape in its most understated form.

The adidas Yeezy Boost 350 V2 'Onyx' is the silhouette in its quietest form. It sits alongside the rest of the Yeezy Boost 350 range, live now at PUSHAS, and every pair is authenticated by hand.

The design story: one colour, all the texture

Most 350 V2 colourways lean on contrast. The 'Onyx' removes it. The upper, the side stripe, the laces and the heel pull tab are all tonal, so the only thing separating one part of the shoe from the next is material. The knit reads differently from the rope laces, the laces read differently from the pull tab, and the sole has its own depth because you can see into it.

The side stripe is where long-time fans will notice the difference: on the 'Onyx', it carries no SPLY-350 text. With no text and no contrasting colour, the stripe becomes part of the upper rather than a label on top of it, which is exactly why the shoe looks so clean from across a room.

Materials and details

The build is classic 350 V2, finished in black throughout:

• Upper: black Primeknit.
• Side stripe: tonal, with no SPLY-350 text.
• Laces and pull tab: black, matching the upper, with a pull tab at the heel for getting in and out.
• Sole: a translucent black sole unit with a full-length Boost midsole visible through it.

That last point is the detail that keeps an all-black shoe from looking flat. The tint darkens the sole to match the upper, but the Boost still shows through, so the midsole keeps its texture.

History and lineage

The 350 V2 story goes back to 24 September 2016, when the 'Beluga' became one of the earliest 350 V2s to release. Six years on, the 'Onyx' took the same silhouette in the opposite direction: no contrast, just tone.

The 'Onyx' dropped on 20 June 2022 alongside the 'Bone'.

It came back again on 31 May 2023, this time as a draw on the adidas CONFIRMED app. That release was part of the first batch of remaining Yeezy stock adidas chose to sell after the partnership ended, and adidas said it would donate a significant amount of the proceeds to organisations fighting discrimination and hate.

How it fits and wears

The 350 V2 runs small, and most wearers report going a half size up from their usual size. If you are between sizes or have wider feet, check the size guide before you choose.

On foot, the full-length Boost midsole does the cushioning work, and the heel pull tab helps when getting the shoe on. The all-black finish means it pairs with nearly everything in a wardrobe, which makes it an easy everyday choice.

How to style the 'Onyx'

An all-black 350 V2 works with almost anything, but it looks sharpest when you let it anchor the outfit. Try it with black or charcoal tapered trousers for a monochrome line from waist to floor, or with relaxed washed-black denim cuffed just above the collar so the knit shows. For contrast, pair it with light-wash denim, cream or grey fleece, and a plain white tee; the shoe grounds the look without competing for attention.
