Can't you wear a open-toed shoes to work?

Our company is a private enterprise. You can wear slippers to work. I am wearing slippers at home now. Our company is of the Internet type, and there is no requirement for dress. You can wear slippers with collars. It depends on which unit. For example, insurance companies can't wear fishmouth shoes and sandals. Don't wear T-shirts, shorts, vests, suspenders, open-toed sandals and sports shoes. I saw someone wearing flip-flops the other day. Ha ha. Then you leave a pair of shoes in the office and change them when you arrive. Oh, my God, I wore flip-flops to work today. In our small company, we don't care what we wear. Anyway, we sit in front of the computer and don't need to meet others. I wear old slippers, too. Haha. Online bosses often wear slippers barefoot ...

In the system, no one wears slippers, and others are basically irrelevant. E-commerce company I changed my sandals into flip-flops on the third day of my employment.
