Do babies always need to wear socks

Do you always wear socks for your baby at home? Is it not good for them to not wear socks once in a while (when not in airconditioned room)? Cause sometimes his feet gets quite hot and also hoping he can “feel” more when using his bare feet. Like kicking things/toys Baby is 9 weeks. Just annoyed at how old people always scold for not wearing socks cause they scared baby’s feet will get cold. His feet do get cold but he doesn’t look uncomfortable.
