In this podcast, Matt Klein and Andrea Myers host a game show called "Buy or Sell." They cover a range of interesting topics including super shoes for 4+ hour marathoners, heart-rate monitors for runners, the safety of Kinvara 14s, changing time for Olympic Marathon Trials, training companion shoes, racing 5Ks in non-plated shoes, super shoes that last less than 100 miles, wider toe boxes in running shoes, non carbon-fiber plates in shoes, and a comparison between Nike's Alphafly versions 1 and 3.
