AOA explained why they ditched the high heels for "Bingle Bangle' comeback.
On the June 11 airing of KBS Cool FM's 'Kim Seung Woo and Jang Han Jun's Mr. Radio', the DJ asked, "Usually, girl groups wear high heels on stage but AOA is promoting in tennis shoes this time. Is there a special reason why?"
Chanmi answered, "Yeah we didn't wear high heels this time. The moment we first saw our choreography, we knew that we couldn't wear high heels. We decided to dance more excitedly with tennis shoes."
Chanmi brought laughter as she added, "If we looked good with the tennis shoes then we would appreciate it if we can get a CF for it."
