I hope this is the right forum for this question, but couldn't find any question quite like mine.

Simply put, what footwear do you typically find yourselves wearing on flights? I am partial to Birkenstocks, but I realize that my ugly toes are probably not the best thing to show off in the cabin (economy or business).

I am gravitating, as a compromise towards the Birkenstock Boston line (they're essentially clogs) and will allow me to wear socks and look somewhat presentable and not like some hick flying for the first time.
