Because calluses are the evolutionary solution to protecting the foot, Lieberman's team set out to assess how these formations might differ from shoes in maintaining grounding and comfort. Their study examined the foot calluses of more than 100 adults, the majority from Kenya. About half of the subjects walked barefoot most of the time, and half mostly wore shoes.
因为老茧是保护脚部而进化出的功能,利伯曼的团队开始评估它在保持脚底舒适度方面与鞋子的不同之处。他们检测了100多名成年人的脚茧,其中大多数来自肯尼亚。大约一半的受试者大部分时间都是赤脚行走,一半的受试者主要穿着鞋子。
Among the barefoot walkers, the thickness of the calluses did not dampen tactile sensitivity, or the ability of the foot to feel the sensation of the ground while walking. Shoes, with their cushioned bottoms, clearly mute this sensation.
在赤脚行走的人当中,老茧的厚度并不会降低触觉的敏感性,也不会降低步行时脚部对地面的感知力,而软底鞋明显地减弱了这种感觉。
However, very thick calluses don't simply act like shoe cushions. The callus thickness can protect against heat or sharp objects, providing comfort and safety, like shoes can. But the sensory receptors in the foot that detect ground surface differences still transmit signals to the brain.
然而,厚老茧并不像鞋底一样简单地起到缓冲作用。茧的厚度可以防止高温或尖锐的物体,就像鞋子一样提供舒适和安全。但是,脚内检测地面差异的感觉受体仍然会向大脑发送信号。
