Why did Aisha disobey the Hadith: "None of you should walk in a single sandal," and what was the reason for her not believing Abu Hurairah when he conveyed the Hadith?

It appears that Aisha, may God be pleased with her, was not aware of the prohibition issued by the Prophet, peace and blessings be upon him. Therefore, she objected to Abu Hurairah's narration, thinking that he had made a mistake in his transmission due to her lack of knowledge of the prohibition. She is not infallible, and her action cannot be used as an argument against the saying of the Prophet, peace and blessings be upon him.
