The wiping on the slippers and socks: As for the Imamis, following their predecessors - following the Imams of the pure family - [their view] is that they do not allow the wiping on the slippers, whether that be at home or on a journey. For our proof, the saying of the Almighty is sufficient. He said: "And wipe your heads and feet to the anklebones." This [verse] imposes the obligation of wiping on the feet themselves. Where did the wiping on the slippers come from? Has this verse been abrogated? Or is it ambiguous? Never, on the contrary - and this is unanimously agreed upon - it is amongst the unambiguous verses which are [part of] the mother of the book. The exegetes are agreed that there is no abrogation in the chapter of Ma'ida (chapter 5) which includes the verse on the wudu except for one verse "O you who believe, do not violate the sanctity of the symbols of God (5:2)." Some of them have claimed that it, not other verses of the blessed chapter, have been abrogated.
