First, assuming that you are not wearing socks (and wouldn't thigh high stockings be totally in appropriate?) - - -
Do you trim your toenails before a GYN exam? And, if you polish them, do you reapply the polish?
For me, whether or not I am wearing socks is not an issue because I am always asked to remove them. When I asked why, I have been told by different medical professionals that - even though it's a GYN exam - the doctor does look at your feet for other health issues, circulation, etc.
And - yes, I do trim my toenails before the GYN appointment; I do not wear polish but, if I did, I would only reapply it if it looked bad. I'd probably just remove it.
