The pair was originally released in North America and South America only.
One of the biggest Yeezy releases of the year so far was the Adidas Yeezy Boost 350 V2 "Clay." The shoe was part of a three-sneaker pack, with each pair being region-locked. The "Clay" model was for those in North, Central, and South America and so far, it has some pretty hefty resale prices. Demand was high for the sneaker although as is usually the case with Yeezy's, the demand was somewhat deflated.
If you missed out on the shoe the first time, you'll actually have a second crack at it although unfortunately, it won't be for adult sizes. According to Sole Collector, Adidas plans to re-release the "Clay" colorway in kids and infant sizes on May 18th. Kanye West has been making a concerted effort to sell Yeezys that will fit the whole family. The fact that the smaller sizes are restocking is further proof that this effort is actually being made and not just an empty promise.
