Going Barefoot in the office

I started my new job as a drug and alcohol worker last week. It is going okay, but there is still a lot of training to do and it is a bit of a drive to where I am currently working in Hemel Hempstead.

A colleague yesterday had removed her shoes and was going barefoot in the office. I have not done that myself since starting, though I did in my last workplace. It might be considered unprofessional, so I wait for somebody else to do it first. I have been wearing flip flops, anyway, so my feet are comfortable enough.
