Q. Do I have to repeat my entire Wudhu if I took off my leather socks after making Masah on it but before the time ends?
A. The removal of the Khuff (leather sock) terminates the Masah made upon it. Upon the removal of the Khuff, the washing of the feet will be necessary to perform Salaah etc. There is no need to repeat the entire Wudhu. (Tahtaawi Ala Maraaqil Falaah 1/133)
Allah Ta’ala Knows Best
