Do you have calluses on your feet? Don't fear them, though. New research has revealed that foot calluses — thickened skin that forms naturally when one walks barefoot — have evolved to protect the feet and provide for comfortable walking in perhaps ways that shoes can't match.
你脚上有茧吗?不要怕它们。新的研究表明,脚茧作为一种赤脚行走时自然形成的厚皮,可以让我们的行走更加舒适,还能起到保护脚的作用。某种程度上来说,穿鞋子都达不到这样的效果呢。
Unlike shoes, foot calluses offer protection without compromising sensitivity or gait, according to a study published in June online in the journal Nature. Shoes, in contrast, reduce sensitivity in the foot and alter the way that the impact forces transfer from the foot to joints higher up the leg.
《自然》杂志6月在线发布的一项研究表明,与鞋子不同的是,脚茧提供的保护并不会影响脚部的敏感度和步态。相比之下,鞋子会降低脚部的敏感度,并会改变从脚部传递到腿部上方关节所受到的冲击力。
The researchers — from institutes in the United States, Germany and Africa — stressed that their findings don't demonstrate that walking barefoot is healthier than walking in shoes. At its core, the study is about human evolution.
来自美国、德国和非洲研究机构的专家强调,他们的发现并不能证明赤脚行走比穿鞋走路更健康。这项研究的核心是人类进化。
