How have they hidden it?
For the geeky readers out there, you may have noticed from the World Athletics website that Adidas had two new shoes approved on September 8. These were the Adidas Adios Pro Evo 1 and the Adidas Adios Pro Evo v2. Interestingly, these two shoes never appeared on the WA list of approved shoes as development shoes. They appeared directly as approved. Recently, this is what companies do to keep their shoes as secret as possible, and Adidas definitely managed to keep the Adidas Adidas Pro Evo 1 secret until today.
