舒適度高的運動鞋可以減少運動傷害的可能性，並且可能改善神經肌肉對平衡的控制，也被認為能降低耗氧量，提高跑步經濟性。本研究採用學者提出的舒適度過濾器假說，希望依據足底壓力數據協助個體找到最適合的運動鞋。方法為利用有89個分佈位置點智慧鞋墊，透過可量化的足底壓力數值，進行數值分析或建立模型，探討個體的舒適度最佳值範圍，並嘗試從個體的足底壓力分佈，預測其感覺最舒適的鞋子，希望在未來幫助運動員或休閒民眾找到最適合的運動鞋，以期藉此降低運動傷害發生機率。結果顯示，不同個體的主觀舒適度感覺無法比較或找出規律性，舒適度與足底壓力的關係是因人而異的。因此以個體進行足壓及舒適度之關係的預測可能是比較好的方式。智慧鞋墊89個分佈位置點的足底壓力值，以多項式模型進行最佳化計算，預測結果之RMSE為11.05，舒適度平均誤差值約為7%，可以用來預測舒適度量值接近或排序第一、二名（高舒適鞋）。然而因少量資料做出的數值判斷有限制，建議未來能收取更多的資料，進行非線性辨識及研究。

Enhanced footwear perceived comfort may reduce the likelihood of running injuries and improve neuromuscular control of balance, which is also thought to reduce oxygen consumption and improve running economy. This study adopts the comfort filter paradigm to investigate the relationship between the footwear perceived comfort and plantar pressure distribution. The plantar pressure values ​​of 89 points of the smart insole are used to conduct numerical analysis and build models to explore the optimal range of individual comfort. They are also used to predict the higher ranked comfortable shoes, with the forthcoming aim of assisting athletes or the general public to find suitable shoes and enjoy sports. The results show that the subjective comfort of different individuals cannot be compared or used for finding a regular pattern, and the relationship between comfort and plantar pressure varies from person to person. Therefore, the better way to predict high comfortable shoes is by using the individual relationship between plantar pressure and perceived comfort. Based on the plantar pressure values ​​of 89 points of the smart insole, an optimized polynomial model was built. The RMSE of the predictive result is 11.05, and the average error value of the comfort scale is about 7%, which can be used to predict the high comfort shoes. Generalization of the present results is limited due the amount of data in this study. It is recommended that future studies collect more data for in-depth research, by identifying nonlinear relationships between plantar pressure distribution and perceived comfort.
