Abstract：Purpose: This study was designed to evaluate the cushioning properties of four marketing slippers in different impact heights and compared with a running shoe with an air cushion. Method: Four types of slippers that were sold at the market were used to compare their shock absorbing ability (SAA) and offer references for purchasers. All shoes were placed on the shock absorbing ability test instrument (SAATI) for survey. According to the procedure, SAATI was adjusted at 3 heights (3cm, 4cm and 5cm) to impact the shoes. At each condition, the impact was done 6 times repeatedly and independent two-way ANOVA was used to compare SAA of those shoes. Results: The main findings of the study were as follows; i). The higher impact height increased the peak reaction force and the max loading rate. ii). The data of the peak reaction force and the max loading rate: shoe 2＞ shoe 1＞ shoe 3＞ shoe 4. iii). The data of shoe 1､3 and 4 were smaller than shoe 5. iv). Shoe 4 reduced 17-21% peak reaction force compared with shoe 5; shoe 3 reduced 10-13% peak reaction force compared with shoe 5. v). The material of shoe 1 was soft. After a long time used, the thickness of the slipper would be attenuated and the ability of cushioning would be decreased. Conclusion: Purchasers should choose the shoes with good shock absorbing ability to reduce the injuries because the different slipper could offer different shock absorbing ability. (Full text)
