Shoes on is slobbish to me. However, I'll presume innocence due to cultural ignorance and/or health reasons such as Deep Vein Thrombosis (DVT)

Preventing Blood Clots
Wear loose-fitting clothes, socks, or stockings.
Raise your legs 6 inches above your heart from time to time.
Wear special stockings (called compression stockings) if your doctor prescribes them.
Do exercises your doctor gives you.
Change your position often, especially during a long trip.
