Footwear comfort in many clinical situations is dependent on the ability of the 'shoe' to redistribute plantar pressure. Offloading the metatarsal heads may be achieved by fitting an insole, but recently a new design of shoe with a curved under sole (Masai Barefoot Technology or "MBT shoe") has been advocated. The aim of this study was to directly assess the effect of such shoes on gait pattern.
Normal subjects were recruited and asked to walk sequentially in (a) flat-soled training shoes and (b) midfoot bearing shoes (MBT shoe). Mean and peak pressures in four anatomically defined areas of the foot, and the total area of sole contact were measured electronically by an in-shoe system (Pedar Ltd., UK).
Standing in the Masai shoes resulted in a 21% lesser peak pressure under the midfoot and an 11% lesser peak pressure under the heel in comparison to the figures found when patients wore their training shoes. There was a 76% compensatory increase in pressure under the toes. In essence there was a significant shift in pressure towards the front of the foot.
在许多临床情况下，鞋类的舒适度取决于“鞋子”重新分配足底压力的能力。通过安装鞋垫可以减轻跖骨头的压力，但最近有人提倡一种新型的鞋底弯曲的鞋子（马赛赤足技术或“MBT鞋”）。本研究的目的是直接评估此类鞋子对步态模式的影响。
招募正常受试者，要求他们依次穿着（a）平底训练鞋和（b）中足承重鞋（MBT鞋）行走。通过鞋内系统（英国Pedar有限公司）以电子方式测量足部四个解剖学定义区域的平均压力和峰值压力，以及鞋底接触的总面积。
与患者穿着训练鞋时相比，穿着马赛鞋站立时，中足下方的峰值压力降低了21%，足跟下方的峰值压力降低了11%。脚趾下方的压力有76%的代偿性增加。本质上，压力显著向前足转移。
