The objective of this study was to explain the effects of consistency in sports goods consumers’ social norms and the reference group’s standards on consumption behavior and to provide basic information on consumers’ loyalty to products. For this study, we distributed a total of 480 questionnaires to those sampled through non?probability sampling from people living in small and medium cities including Seoul and having experience in the purchase of sports goods. Of the questionnaires, 470 (97.9%) were recovered, and excluding 24 questionnaires inadequately answered or not reliable, we used 456 questionnaires as the valid sample for analysis. Collected data were coded and entered into the computer, and statistically processed using SPSS Statistics 18. In order to analyze the effects of the reference group’s standards and consistency in social norms on consumers’ attitude as purposed by this study, we analyzed social?statistical characteristics through frequency analysis, factor analysis, correlation analysis and multiple regression analysis. According to the results, first, social consistency affecting trust in products among consumption attitudes was the reference group’s standards and consistency in social norms. Second, the variable influencing loyalty to products among consumption attitudes was the reference group’s standards, and consistency in social norms did not have a statistically significant effect.
