The use of high heels is widespread in modern society in professional and social contests. Literature showed that wearing high heels can produce injurious effects on several structures from the toes to the pelvis. No studies considered shoe length as an impacting factor on walking with high heels.
The aim of this study is to evaluate walking parameters in young healthy women wearing high heels, considering not only the heel height but also the foot/shoe size.
We evaluate spatio-temporal, kinematic and kinetic data, collected using a 8-camera motion capture system, in a sample of 21 healthy women in three different walking conditions: 1) barefoot, 2) wearing 12 cm high heel shoes independently from shoe size, and 3) wearing shoes with heel height based on shoe size, keeping the ankles' plantar flexion angle constant. The main outcome measures were: spatio-temporal parameters, gait harmony measurement, range of motion, flexion and extension maximal values, power and moment of lower limb joints.
Comparing the three walking conditions, the Mixed Anova test, showed significant differences between both high heeled conditions (variable and constant height) and barefoot in spatio-temporal, kinematic and kinetic parameters.
Regardless of the shoe size, both heeled conditions presented a similar gait pattern and were responsible for negative effects on walking parameters. Considering our results and the relevance of the heel height, further studies are needed to identify a threshold, over which it is possible to observe that wearing high heels could cause harmful effects, independently from the foot/shoe size.
高跟鞋在现代社会的职业和社交场合中广泛使用。文献表明，穿高跟鞋会对从脚趾到骨盆的多个结构产生有害影响。尚无研究将鞋长视为影响穿高跟鞋行走的因素。
本研究的目的是评估年轻健康女性穿高跟鞋时的行走参数，不仅要考虑鞋跟高度，还要考虑脚/鞋的尺寸。
我们使用8台摄像机的运动捕捉系统，对21名健康女性在三种不同行走条件下的时空、运动学和动力学数据进行了评估：1）赤脚；2）穿12厘米高跟鞋，不考虑鞋码；3）根据鞋码穿不同鞋跟高度的鞋子，保持踝关节跖屈角度不变。主要观察指标包括：时空参数、步态协调性测量、运动范围、屈伸最大值、下肢关节的功率和力矩。
比较三种行走条件，混合方差分析显示，在时空、运动学和动力学参数方面，两种高跟鞋条件（可变高度和固定高度）与赤脚之间均存在显著差异。
无论鞋码如何，两种高跟鞋条件下的步态模式相似，且均对行走参数产生负面影响。考虑到我们的研究结果以及鞋跟高度的相关性，需要进一步研究以确定一个阈值，超过该阈值可能会观察到穿高跟鞋会产生有害影响，而与脚/鞋的尺寸无关。
