adidas via eBay offers its adidas Men's Questar Tnd Running Shoes in Grey Four or Collegiate Royal for $44.99. In-cart, that drops to $33.74. With free shipping, that's the lowest price we could find in any color by $16, although we saw it for $12 less in our Amazon Prime Day mention from last July. They're available in select sizes from 6.5 to 15.
