不同的運動項目由於運動型態及要求不同，所以從事不同的運動就必須穿著專項 運動鞋，以減低傷害並提昇表現，這已經是眾所皆知的了，但是在外表上、結構上一樣的市 售運動鞋都採用大量生產，不一定能符合個人的需求，忽略了每個人的腳型的特性，而這些 因素卻也會影響到避震功能及反彈能力等，甚至還會因此造成運動傷害。本文則是要以田徑 選手為對象，考慮其足型不同的特點，針對其訓練鞋、競賽用釘鞋進行調整及測試，期望能 減低因鞋類不合適而造成的傷害情形，並由於對疲勞及傷害的改善，能在訓練效果上有所幫 助。結果顯示在訓練鞋部分，運動員感覺情況很好，疲勞以及疼痛的情形已得到改善。而對 於運動員競技鞋的部分，由於競技鞋本身的目的在於求得最佳成績表現，所以儘管所替換的 鞋墊已經是較一般運動鞋墊硬，仍然因為材質過於柔軟，損失往下推蹬的力量，同時反作用 力的時間無法配合動作，造成運動員的無力感。
