Girls, please answer, will your feet sweat when you walk in sandals? Will there be foot odor?

Oh, yes, because generally speaking, wearing sandals is not wearing socks. Most of you wear socks when you wear other shoes. Even if you sweat, foot sweat will be absorbed by socks. If you change your socks every day, your shoes won't smell too bad. However, direct contact between sandals and feet will absorb foot sweat and breed bacteria.
