The Adidas Yeezy 350 Boost will be releasing this weekend with hype all over, much like the high-top 75o Boost that released back in February.
According to Modern Notoriety's Oscasr Castillo, his pair ran about a size too big.

This shouldn't be too surprising, in my opinion. The Yeezy 750 Boost ran a size too big as well.
If you're planning to cop on Saturday, make sure to go down a size.
