Vinaya Pitaka - Monastic Rules
Bhikkhu Vibhanga - Sekhiya 61: Not to teach the dhamma to someone who is wearing shoes unless they are ill.
- Translated from the Pali by I.B. Horner.
… in Anāthapiṇḍika’s monastery. Now at that time the group of six monks taught dhamma to (someone) wearing shoes … " …
‘I will not teach dhamma to (someone) wearing shoes (and) who is not ill,’ is a training to be observed."
Dhamma should not be taught to (someone) wearing shoes (and) who is not ill. Whoever out of disrespect teaches dhamma to (someone) mounted on (shoes) or (with shoes) fastened on or (with shoes) unfastened (and) who is not ill, there is an offence of wrongdoing.
There is no offence if it is unintentional … if he if the first wrong-doer.

2 "na pādukāruḷhassa agilānassa dhammaṃ desessāmīti sikkhā karaṇīyā"ti. (61:206)
3 na pādukāruḷhassa agilānassa dhammo desetabbo. yo anādariyaṃ paṭicca akkantassa vā paṭimukkassa vā omukkassa vā agilānassa dhammaṃ deseti, āpatti dukkaṭassa.
