Greeting my friend, while working bare foot may be beneficial and helps us connect with outside world it could be very detrimental if the act is carried out in a thornic environment, Too many people and culture working barefoot means a lot and signifies something, It is better we walk barefoot in a secure place as you said you feel convenient when the process is carried out in the comfort of your bedroom because of your previous accident of matching a burning rubber, that shows that this act is not all rosy. Goodluck friend👍
