Running shoes are carefully designed to cushion your feet and provide arch support and padding and all that stuff.
凭借科学严谨的设计跑鞋能够缓冲脚部压力而且为足弓，鞋衬及衬垫提供支撑。
Run without shoes and you'll tear up your foot on rocks and pebbles.
如果在岩石及鹅卵石上光脚跑步，你的脚会被磨破。
But studies have shown that running shoes can do more harm than good.
但是最近研究表明跑鞋带来的危害大于益处。
When you run wearing shoes, you tend to land on your heels.
当你穿鞋子跑步时，你倾向于脚后跟着地。
Somehow, that's what most running shoes make us do.
某种程度上，大多数跑鞋都会使我们这样着地。
But run barefoot, and you'll naturally land on the balls of your feet.
但是光脚跑步会使你自然而然用前脚掌着地。
Striking the ground this way is less forceful than landing on your heel.
这样着地远比用脚后跟着地带来的冲力小。
So it's likely that running barefoot may reduce injuries to the knee and lower back.
因此光脚跑步可能会减少膝盖和背部下部受到的伤害。
