Man can go to work with open shoes in the hot season?

Scandal. Lol. I wear fully covered shoes all the time and have no reason to complain for it. Some guys like to wear sandals all the time. I guess it is what you are used to. If I suddenly switch to sandals, I would not really feel too comfortable. The airy breeze between my toes will make me go like...something is amiss

It depends on the work environment and the country and culture. In some places it would be acceptable and in other places it would be considered too casual.

depends on where you work certain jobs require you to wear shoes that dont expose your feet like in a kitchen it would not be exceptable as to much can happen also in a place with alot of heavy equipment.

I have my boots that I love and would wear them year round if I could get by with it. I have a pair sneakers and I have my saddles. I love to mix it up and not be so predictable when it comes to my shoes.

It's a physiologic need but in some work place it's not possible to go with them in your feet.
