It is permissible to wipe over the Khuffs (leather socks) or the ordinary socks that fully cover the area required to be washed. However, it is not permissible
to wipe over the sandals because they do not fully cover the area that must be washed during Wudu'. Therefore, you should repeat this Salah, as you did not carry out the wiping procedure correctly.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
