Doctors of Running Podcast

We're heading into the new year with a new round of Buy or Sell, one of our favorite podcast games. If you don't know the drill, we force ourselves to decide whether we buy or sell an idea, shoe, treatment, etc. Today, Nathan, David, and Matt debate the Saucony Endorphin Azura (Shift 3 replacement??), the venerable ASICS Nimbus, whether runner's high really exists, and much more. Want your idea on the next edition of Buy or Sell? Email us at [email protected]!
