It has become one of the latest running crazes, said to reduce the risk of injuries and back pain.
目前，光腳跑步很流行，人們說這種跑步方式可以有效緩解背部疼痛。
But experts have warned that the growing number of runners using 'barefoot' five-finger running shoes could very easily end up injured.
但是，專家聲稱這種方式對人體有害。有關研究中發現，光腳跑步的方式會增加腳部骨頭受損的風險，甚至導致應力性骨折。而女性則是受傷的高危人群。
Researchers at Brigham Young University in the U.S found that runners who make the switch from normal trainers to barefoot shoes too quickly suffered an increased risk of injury to bones in the foot, including possible stress fractures.
支持光腳跑步的人提出自己的看法，他們認為運動鞋會限制腳部的自然運動模式，引發人體某些部位的疼痛感。因此部分熱愛跑步運動的人士選擇不穿運動鞋或減少腳部保護裝置的方式來進行運動。
At the end of the 10-week period, MRIs were again conducted. The MRIs revealed that those who had done more running in the minimalist shoes suffered a greater number of injuries and inflammation.
光腳跑步時，腳部受到的沖擊力量過大，時間太快，骨頭在承接下次沖擊時并未做好充分的準備。專家建議，想要換一種運動鞋型跑步的話，必須進行為期至少10周的鞋型適應期，跑步路線長度應當比以前的要短一些。
Foot specialists said many injuries resulted from switching from trainers to barefoot too quickly.
很多因為光腳跑步受傷的人也是因為調整期太短了，脫了鞋就馬上進行和以前一樣強度的訓練。
