I am a medical student and have to be on my feet 12 hours at a time. I was hoping I could get some suggestions on what dress shoes are known to be extra comfortable. Hate to make things hard for you guys, but I'd really like them to be less than $100 (I know, not going to find much but I'm a med student with $200,000 of loans so I have to do what I can lol). I also prefer brown shoes to black, but obviously this is not a big deal. Thanks!!
