The study's research model was influenced by Aaker's consumer-based brand equity model. Brand loyalty, perceived quality, brand awareness, and brand association were independent variables. Dependent variable was consumer’s purchase decision. Data was obtained from 407 respondents in Turkey using an internet survey to test the hypothesis. The respondents' favorite sports shoes brand was used to frame the questions.

The results showed that brand equity dimensions affect Turkish consumer’s purchasing decisions based on consumer’s favourite sport shoes brand. Statistically, there is positive impact of both BAW (coefficient 0.853, p=0.000<0.01), BL (coefficient 0.255, p=0.019<0.05) on CPD. Both PQ (p=0.870>0.05) and BA (p=0.538>0.05) have no positive impact on CPD.
