The aim of this study was to identify the factors affecting repurchase intention for sports products. It was an applied, correlational, quantitative study based on structural equation modeling and conducted in the field. The statistical population consisted of all customers of reputable sports stores in Tehran, and the sample size was determined using the structural equation modeling method; accordingly, 225 questionnaires were collected. Data were gathered using the revised questionnaire of factors affecting repurchase intention developed by Lam and Bee (2014) and the repurchase intention questionnaire by Chiu and Won (2016). The face and content validity of the questionnaire were confirmed by sports marketing professors. Construct validity was established through convergent validity, and reliability was assessed using Cronbach’s alpha (ranging from 0.74 to 0.89) and composite reliability (ranging from 0.81 to 0.92). The research hypotheses were tested using partial least squares structural equation modeling in SmartPLS software. The results showed that, except for fashion and impulse buying, the other components quality, brand, price, confusion during purchase, habit, endorsement, and recreational buying had a significant effect on customers’ repurchase intention. Therefore, manufacturers and retailers of sports products should strengthen repurchase behavior by improving product quality, reinforcing brand strength, setting appropriate prices, reducing buyer confusion, and creating a pleasant and recommendable shopping experience.
