I actually didn't believe it when somebody told me that once, so i searched on it.
Explanation:
Authentic scholars and mujtahids like Ibn Taymiyyah have affirmed the way of wiping on such socks provided they are thick and not transparent.
“Wiping with wet hands on leather socks, instead of washing the feet, is not only allowed when done in conformity with the prescribed conditions but also reviving a Sunnah of the Prophet (peace and blessings be upon him). It is making use of a rukhsah (allowance) granted to us by the Law-giver and as the Prophet (peace and blessings be upon him) said, “Allah loves people to make use of His allowances just as He loves them to comply with His commandments.”
yes, this is called masah, wiping your hands under your feet with socks on. Masah can be done over leather socks (khuffs) by wiping the covering of the feet, as long as the (Wudu or Ghusl) remains unbroken between prayers, BUT it is not permissible to do masah if the leather socks have significant ODOR... heheeee
