Question: If a person is wearing two socks and wipes over the top in the early morning and in the afternoon due to the heat, he removes the top layer. Can he wipe on the one remaining?
Answer: “There is no harm to wipe because the feet are covered. So as long as he has more than one sock and he removes one of the socks, then the foot does not cease to remain covered. Wiping is upon what covers the foot”.
