Wudu in the shower must the feet and hair be dried before making ablution in the shower?

I’ve heard that making wudu in the shower that your hair and feet must be dry or partly dry before marking abolition in the shower. So I’m in a standing shower so let’s just go worse case scenario. What if my feet was completely soaked can I still make ablution? Also what if the wetness of my feel like rolls of while being in the shower so the foot is wet but like not in large amounts?
