Abu Bakr said that the Prophet (ﷺ) gave permission for the traveller to wipe over his shoes during three days and nights, and for one who was not travelling during a day and a night, if be had been in a state of purity when he put them on. Al-Athram transmitted it in his Sunan. Ibn Khuzaima and Daraqutni also transmitted it. Al-Khattabi said in al-Muntaqa that the isnad is sound.
