Abstract: Step friction of human is a phenomenon of interval friction between foot and floor when persons are walking. The coefficient of friction is directly related to human’s safety. Major factors influencing coefficient of friction between shoe and floor were formulated. The factors including materials, lubricating status of floor, groove of shoe soles, form and height of heels and gait parameters etc. The problem in the current research was analyzed. Finally, the research focus and aim in the future were presented.

Key words: step friction_shoe sole materials, floor materials, lubricative status of floor, groove of shoe soles, form and high of heels, gait parameter;
