隨著時代日新月異的變遷，人們對於鞋類的購買、穿搭屬實愈來愈重視，不論是運動鞋、包鞋、跟鞋或是涼拖鞋都是如此。炎炎夏日之中，穿著夾腳拖鞋的消費者日漸據增，同時也伴隨著對身體健康造成的傷害，例如缺乏足弓支撐、足踝問題、因姿勢不正確而造成腰背部慢性傷害等問題；根據國外研究指出，長期穿著夾腳拖甚至可能會改變穿戴者的姿勢、步態等健康上的問題。
因此，本研究最大的價值是直接針對足部與鞋的關係來進行一連串相關的實驗設計，分別針對幾何、力學與實際受試者問卷調查三大部分進行研究，並使用Havaianas夾腳拖作為比較例，與自製鞋款(粗帶、細帶)測試結果進行討論。首先幾何的部分是利用相機拍攝行走過程中後腳跟開合面積的差異；其次力學的部分則細分為動態足底壓力量測(F-scan)及單點夾力量測(ELF)，針對足底力量軌跡( COF)、足弓平均壓力接觸面積與單點夾力做細部討論，而測試結果則使用SPSS統計軟體進行擬合分析；問卷調查的部分則針對力學、材質及受試者觀感作調查。
實驗結果顯示，幾何量測的部分，利用影像拍攝的方式記錄行走的步態可有效計算行走中腳跟開合的面積差異，自製鞋款(粗帶、細帶)與Havaianas夾腳拖相比，具有較小之開合面積(p<0.05)；力學量測的部分，自製鞋款(粗帶)具有較小的夾力值(p<0.05)，可減少穿戴者在第一與第二蹠趾骨所施的力，在F-scan的測試中測得較大的足弓接觸面積；問卷調查結果則指出受試者最重視穿著上的舒適度，因此在鞋款的設計上，仍須針對實驗結果與受試者意見之間做綜合性平衡。
而上述實驗結果可推論客製化的夾腳拖鞋鞋款比Havaianas此品牌的夾腳拖鞋具有優勢，這也達成了本研究的預期。未來在夾腳拖鞋的研究上能有更進一步的突破，在夾力的量測方面的感測片裝置若能直接鑲嵌在腳夾處，那麼實驗可能會更便利更準確，實驗的條件限制也就能降低，以達到實驗需求。

To date, people pay a lot of attention to the shoes people are wearing (ex: sports shoes, shoes, heels, sandals, and flip-flops). In particular, the flip-flops offer a wide range of brands attractive labels covering various segments of the marketing whilst. However, flip-flops do harm to health such as lack of arch support, bad posture, low back injury and other issues. Many researchers found that the flip-flops may change the way for wearer’s walk and sometimes permanently. These changes may wreak havoc on the rest of the body, with distinct and noticeable effects on everything from the wearer’s posture to their gait.
Thus, this study investigated the relationship between the foot and flip-flops with a series of related experimental design by measuring the clamping force of the flip-flops. The three major parts of this study, including the geometric, mechanical and practical subjects were investigated by comparing with Havaianas and homemade’s shoes (the wide version and narrow version of shoelaces). The first part of the geometry is using the camera to shoot the difference between the heel opening and closing area during walking process. In the second place, the mechanical part is subdivided into dynamic foot pressure measurement (F-scan) and single point grip force measurement (ELF) for discussing the foot strength trajectory (COF), the average pressure contact area of the arch with a single point of grip force. The experimental test results were analyzed using Statistical Product and Service Solutions (SPSS) statistical software. Finally, the questionnaire investigation would be conducted for mechanics, material and subject opinion.
The experimental results show that using the recorded image recorded walking gait can efficiently compute the difference in area of the heel of the opening and closing travel. Besides, the homemade shoes have a smaller opening and closing area (p < 0.05) in the geometric measurement section as compared to the homemade shoes (the wide version and narrow version of shoelaces). In the measurement part of mechanics, homemade shoes (the wide version of shoelaces) have a small gripping-force (p < 0.05), while reduces the applying-force by the wearer in the first and second metatarsal as well as the larger arch contact area by the F-scan test. The results of questionnaire investigation indicate that subjects are most concerned about wearing comfort. Therefore the dynamic comprehensive balance between experimental results and the views of the subjects should be found for designing the shoes.
In summary, experimental results of this study can prove that custom footwear flip-flop than Havaianas this brand of flip-flop has an advantage, which also reached the expected study. In the future, if the sensor can directly allocate and place in the foot clip while maintaining the desired accuracy, it may be used to improve the efficiency and accuracy of this study.
