In this paper, four pairs of insoles with different comfort characteristics were used to investigate the relationship between the pressure distribution under the foot and running shoe comfort. Fourteen male subjects were tested in four insole conditions by walking and running on a treadmill. The pressure at the plantar surface of the foot was measured by using an EMED pressure-measuring insole. For walking there were significantly higher pressures and forces in the midfoot area and significantly lower pressures in the medial forefoot and hallux area by wearing the most comfortable insole compared with wearing the least comfortable insole. The shift of the pressure from forefoot to midfoot for the most comfortable insole provided an even distribution of the pressure at the plantar surface of the foot. The results also demonstrated that the path of centre of force at the plantar surface of the foot moved to the lateral aspect of the foot for the most comfortable insole. For running, only the pressure in the medial forefoot area was found significantly lower for the most comfortable insole than for the least comfortable insole. The results of this study indicated that the pressure distribution between the plantar surface of the foot and the shoe could detect the change of shoe comfort. Thus it is a suggestion that pressure measurement may be related to understand factors important for shoe comfort. Comfort of sport shoes is important for the appropriate execution of sport activities. Additionally, comfort may influence fatigue and possibly the development of injuries. The quantification of comfort of sport shoes and the understanding of mechanical and/or biological functions related to it may be enhanced with the use of pressure measurements between the plantar surface of the foot and the shoe sole.

本文采用四对舒适特性不同的鞋垫,研究了脚底压力分布与跑鞋舒适度之间的关系。通过在跑步机上行走和跑步,在四种鞋垫条件下对十四名男性受试者进行了测试。使用EMED测压鞋垫测量脚的足底表面的压力。步行时,与穿着最不舒适的鞋垫相比,穿着最舒适的鞋垫,中足区域的压力和力量明显更高,而前足内侧和拇趾区域的压力明显更低。对于最舒适的鞋垫,压力从前脚向中脚的转移提供了脚的足底表面压力的均匀分布。结果还表明,对于最舒适的鞋垫,脚的足底表面的力中心路径移至脚的侧面。对于跑步,最舒适的鞋垫仅发现前脚内侧区域的压力明显低于最不舒适的鞋垫。这项研究的结果表明,足底和鞋子之间的压力分布可以检测到鞋子舒适度的变化。因此,建议压力测量可能与了解对鞋舒适性重要的因素有关。运动鞋的舒适性对于适当执行体育活动很重要。此外,舒适性可能会影响乏力,并可能影响伤害的发展。可以通过使用脚的足底表面和鞋底之间的压力测量来增强对运动鞋的舒适性的量化以及对与其相关的机械和/或生物学功能的理解。
