The type of footwear is one of several factors that affect foot pressure. Despite its usefulness in identifying pathology and preventing and treating foot-related diseases, the type of shoes has been investigated and compared in only a few studies. This study aimed to investigate differences in plantar pressure, induced by flat, running, and high-heeled shoes in healthy, young women.
A total of 27 healthy women (27 feet) with a mean age of 21.5 ± 2.03 years were included in this study. Based on demographic data, radiologic measurements, clinical scores, temporal gait parameters, and kinematic parameters of gait, we confirmed the participants had normal feet. Then, pedobarographic data were measured by dividing each foot into seven regions to compare the three types of shoes. Peak plantar pressure and pressure-time integral were calculated using the Pedar-X system. The one-way analysis of variance and the Kruskal-Wallis test with Mann Whitney -test were used for statistical analyses.
Regarding the 7 regions of the foot, flat shoes resulted in a significantly higher pressure than running shoes in the hallux and lesser toes and the highest pressure in the metatarsal head (MTH) 3-5 and the hindfoot. In contrast, in the MTH 1 and MTH 2 regions, the high-heeled shoes had the highest measured pressure, followed by the flat shoes. Lastly, there was no high pressure in running shoes in any region except for the midfoot compared to the other shoes.
It can be inferred from our findings that flat and high-heeled shoes can generate a considerable burden on specific parts of the foot, which will aid in choosing appropriate shoes. Also, wearing running shoes places less burden on the overall foot.
鞋类类型是影响足底压力的几个因素之一。尽管它在识别病理学、预防和治疗足部相关疾病方面非常有用，但仅在少数研究中对鞋子的类型进行了调查和比较。本研究旨在调查健康年轻女性穿着平底鞋、跑鞋和高跟鞋时足底压力的差异。
本研究共纳入 27 名健康女性（27 只脚），平均年龄 21.5±2.03 岁。根据人口统计学数据、影像学测量、临床评分、时间步态参数和步态运动学参数，我们确认参与者的足部正常。然后，使用 Pedar-X 系统通过将每只脚分为 7 个区域来测量足底压力数据，以比较这三种类型的鞋子。使用峰值足底压力和压力-时间积分来计算压力-时间积分。采用单因素方差分析和 Kruskal-Wallis 检验及 Mann Whitney -检验进行统计学分析。
就足部的 7 个区域而言，平底鞋在前足和小脚趾处的压力明显高于跑鞋，在跖骨头部（MTH）3-5 和后足处的压力最高。相比之下，高跟鞋在 MTH 1 和 MTH 2 区域的测量压力最高，其次是平底鞋。最后，与其他鞋子相比，跑鞋在除中足外的任何区域都没有高压力。
从我们的研究结果可以推断出，平底鞋和高跟鞋会给足部的特定部位带来相当大的负担，这有助于选择合适的鞋子。此外，穿跑鞋对整个足部的负担较小。
