Running shoes are carefully designed to cushionyour feet and provide arch support and paddingand all that stuff. Run without shoes and you’ll tearup your foot on rocks and pebbles. But studies haveshown that running shoes can do more harm thangood. When you run wearing shoes, you tend to landon your heels. Somehow, that’s what most runningshoes make us do. But run barefoot, and you’llnaturally land on the balls of your feet. Striking theground this way is less forceful than landing on yourheel. So it’s likely that running barefoot may reduceinjuries to the knee and lower back.

【參考譯文】
跑鞋經(jīng)過(guò)仔細(xì)設(shè)計(jì)用來(lái)緩沖腳的壓力,并提供置于足穹部的鞋襯和襯墊。不穿鞋在巖貨石鵝卵石上跑步,你的腳會(huì)被撕破。但是最近研究表明跑鞋帶來(lái)的危害大于益處。當(dāng)你穿鞋子跑步時(shí),你會(huì)傾向用腳后跟著地。某種程度上,大多數(shù)跑鞋都會(huì)使我們那樣做。但是光腳跑步,你會(huì)自然地用腳掌前部著地。這樣著地遠(yuǎn)比用腳后跟著地帶來(lái)的沖力小。光腳跑步可能會(huì)減少膝蓋和背部下部受到的傷害。
