应该密切关注身体对跑鞋的选择意见

第一是当我们足部着地时是否存在翻转，如果有，程度如何。长期以来，骨科医生、教练和运动员都认为，足部外翻(pronation/over-pronation，或称足踝内旋过度)或内翻(under-pronation，与前者相反)都可能会造成跑步受伤的风险，应使用特定类型的鞋子来加以矫正。

More recently, impact force, or the pounding that we experience with each stride, has alsobeen getting plenty of attention, especially in relation to barefoot running and the question ofwhether we should wear shoes at all. Some barefoot-running proponents claim that runningwithout shoes or in minimal, slipper-like models somehow changes impacts and substantiallyreduces the risk for injuries.

近来，我们跑步时受到的冲击力(即触地反冲力)也日渐为人所关注，在涉及赤足跑步以及我们是否就不该穿鞋的问题上尤其如此。一些支持赤足跑步的人声称，不穿鞋子或者只穿最简单的家居鞋会从某种程度上影响触地反冲力，从而大大降低受伤的风险。

But Benno Nigg, the lead author of the new review, and his colleagues were skeptical. Anemeritus professor of kinesiology at the University of Calgary in Canada and one of the world’sforemost experts on biomechanics, Dr. Nigg wondered whether science really supports the ideathat the right shoes can alter and fix someone’s running form and lessen injuries.
