StadiumGoods via eBay offers the adidas Men's Yeezy Boost 700 Inertia Shoes in Grey for $300 with free shipping. That's the best deal we could find by $13. (For further comparison, most third-party sellers charge hundreds more, or require bidding). This lastest addition to the Yeezy line (released March 9) is available in select sizes from 9.5 to 13.
