The Shoe Companies do not REALLY care about the Athletes (Though most Athletes Think they do) The Shoe Companies do not hire out of goodness of their hearts (As most Athletes think they are) They are Using Athletes for Advertising And if the Athlete is not bringing in Money ABOVE The Companies Return of Investment They are Cut off, Also The Companies Have the Track and Field Athletes sign Non Disclosure Agreements and MOST Athletes think they are doing that To Keep the Contract Details unkown as they care about The Athletes right To Privacy, It is so The Athletes Worth is not known To give the Companies Bargaining Power and signing The Athletes for less than Athletes are Worth.
To Sum it up Shoe Companies are trying To Make Money not because From the bottom of their Hearts they care about the Athletes.
Athletes are better off having a Longtime Mega Millionaire or Billionaire Friend or Relative who honestly care about them Sponsor Them
