The aim of the study was to examine the degree of shock absorption, using two different outsoles-designed of running shoes. Methods: Twelve healthy male college students were required to conduct 3 tests, each for 30 times, with barefoot, wearing NIKE FREE +3 (FREE) and NIKE LUNAR ECLIPSE +2 (LUNAR) shoes. Using the free running speed, and the right foot must touch the force plate. The data are analyzed by one-way ANOVA test with SPSS 18.0 statistical software. Results: The maximum loading rate among the groups shows significant difference (p＜.000). Besides, multiple comparison test of the maximum loading rate also displays significant differences among the three (p＜.05), especially for LUNAR's maximum loading rate, which is the smallest. Conclusion: The loading rate of impact will be affected by different structure and material of shoe. The results of this study showed that LUNAR's outsole possesses better shock absorption than FREE's.
