Why would a stranger in an elevator look at my feet before my face?

For context, I can't tell if this guy was judging me, I wore wedge sandals and had nail polish on, we were standing in an elevator and that's when I ntocied form my peripheral that he Infact started looking at my feet briefly before moving his eyes up to my face. The glances at my face were brief though, only 1 or 2 quick ones. I didn't make eye contact, I just stared straight ahead the whole time
