Matt and David are back with a new installment of Buy or Sell. They debate the merits of data versus hands-on testing in shoe reviews and make the case that the era of 35-39mm being considered max cushion is officially over. They also look ahead at where the industry is heading — from the coming wave of 50mm+ shoes to a future with three tiers of racing footwear and much more.
