Available on Adidas' site and third-party retailer sites like JD Sport, the trainer costs around £140.
But as is often the way with limited-edition sneaker collaborations, hundreds of customers were left venting their rage at the Adidas UK Twitter account after the shoes sold out within hours in Europe.
The shoes went on sale this morning, but visitors from the UK were greeted with inevitable site crashes, queues and the "sold out" screen.
The trainers have already started appearing on eBay UK for as much as £820.
Adidas UK has manfully been answering customer queries on Twitter in the run-up to release, but refused to give customers exact details of timings, possibly to fend off bots.
But multiple users complained of having managed to reach the product page before seeing the message "access denied".

@adidasUK I got to the product page and it booted me off and wouldn't let me check out saying access denied? Sort it out??
Creating massive hype through limited availability and a superstar collaboration is a common technique, as evidenced by the huge online demand for the Balmain x H&M collection last year. But retailers face challenges as savvy consumers turn to bots and other software to make purchases automatically, or struggle to deal with the sheer volume of traffic.
Adidas isn't giving out figures on the Yeezy Boost 350's availability, but one analyst, NPD's Matt Powell, told Marketing this week that US retailers had sold as few as 50,000 pairs. In a market which shifts 3m sneakers annually, the figure was "negligible", Powell said.
And while there might be hundreds of frustrated customers queueing up to buy the sneakers, it isn't clear the collaboration has paid off for Adidas, particularly in the US where it hopes to gain street cred and loyalty.
Ever since the brand announced Kanye West's signing, US sales have actually fallen, though Adidas remains strong in its home turf of Europe.
