In the 5th episode of the Kicksology podcast, host Brian Metzler is joined by Carson Carprara, Senior Director, Global Footwear Product Management at Brooks Running, and Danny Orr, the Senior Business Unit Manager for Innovation at New Balance. Carprara and Orr talk about the evolution of running shoes, the midsole "foam war," the development of shoes with carbon-fiber plates embedded in the midsole, new models just released from Brooks and New Balance, and what’s next in running shoes.

Metzler is the author of the book, "Kicksology: The Hype, Science, Culture and Cool of Running Shoes" and a long-time runner who has competed in races on the track, roads and trails from 50 meters to 100 miles.
