flip flops

Do you think it is okay to wear flip flops to work? Other people at my work are wearing shorts and sandals. As I was leaving the house today, my mom was telling me not to wear flip flops to work, but I have been wearing flip flops to work for about a couple of weeks, and none of my co-workers mentioned anything to me. I like wearing flip flops because I can stretch my feet more under my desk. I can easily sit Indian style on my chair and just feel more comfortable. Also, my feet can breath. I feel so sufficated when I wear tennis shoes. The only problem with flip flops is that I cannot run too much on it. I'll just have to walk fast. I think I have over 10 flip flops at home, most of them black though.
