Doyle bustled in, and we let him pass, unaccosted. The way to activate your fat-burning furnace is by staying below your aerobic threshold鈥攜ourhard-breathing point鈥攄uring your endurance runs. Respecting that speed limit was a lot easierbefore the birth of cushioned shoes and paved roads; try blasting up a scree-covered trail in open-toed sandals sometime and you鈥檒l quickly lose the temptation to open the throttle. When your feetaren鈥檛 artificially protected, you鈥檙e forced to vary your pace and watch your speed: the instant youget recklessly fast and sloppy, the pain shooting up your shins will slow you down. *Nike鈥檚 policy of yanking best-selling shoes from the shelves every ten months has inspired sometruly operatic bursts of profanity on running message boards.
