Are you incompetent?
No, I am not clueless. Do you think there are athletes that are Adidas shoe sponsors and Nike clothing/gear sponsors? I have never seen an athlete be sponsored by Nike for clothing/gear, and Adidas for footwear in the sport of running/track and field. In case you forgot, our sport does not have much sponsorship opportunity anyway.
Does Alexi Pappas actually race in Champion shoes? Or does she wear Nike shoes and cover the Nike logo?
