Abstract

Proper selection of athletic shoes is important for sports related activities to ensure improved athletic performance. The problem that always happened is inadequate data foot measurement for Malaysian population and injuries happened among the athletes. Therefore, there is the need to consider the design requirement for different sports and different foot profile. The objectives of this study are to obtain the anthropometry data of feet profiles for UTeM students, to develop an ergonomic design of shoe sole for UTeM students and to analyse the contact stress of the shoe sole design for UTeM sportsmen. The scope incorporated in this study is collecting anthropometry data using visual graphic measurement. Based on the anthropometry data, the design of inner shoe sole has been done for three foot profile which is normal, high- arch and flat foot print. Then, the analysis of stress distribution and displacement is done in comparing the material, rubber versus ethylene vinyl acetate (EVA) and three type of foot profile. This study found that, flat inner shoe sole recorded the highest maximum stress distribution (28.1301 MPa) and displacement (664.639 mm) for running sports activities whereas for soccer sports activities, the highest maximum stress distribution is high-arch inner shoe sole (572.294 MPa) and maximum displacement is normal inner shoe sole (49413.8 mm). The analysis also found that, rubber material resulted to lower stress distribution (27.889 MPa) and greater maximum displacement (379.141 mm) compared to ethylene vinyl acetate (EVA) material (28.077 MPa, 96.7997 mm). The significance of this study is the anthropometry data of foot will be useful for shoe manufacturers to develop their shoe design for Malaysian athletes. Besides that, the new designs of inner shoe sole are useful for an improved athletic performance as well as reduce injuries of foot due to sports activities
