The study concluded that Self-Image Congruence did not have a significant influence on runners’ purchase intentions for running apparel brands. However, Functional Congruity was considered to be important to runners, and was able to influence their likelihood of purchase intentions for running apparel brands. The findings suggested that runners considered their running apparel as equipment, and hence required their apparel products to meet their performance expectations. The survey data also suggested that most runners, regardless of their level of involvement, exhibit brand loyalty behavior toward running shoes, but not toward running tops or bottoms. However, when considering only running tops and bottoms, runners were more brand loyal to running bottoms. The results ultimately suggested 148 that runners would be more likely to switch brands when purchasing running apparel if they found that a certain product offered more appealing functional attributes.
