Mossic,
When you are looking for something as specific as 'a big foot fetish' it's important to be honest in communication in order to find what you are looking for. Don't feel that you are being rude or disrespectful. Simply state that you have a foot fetish and ask them if their able to accommodate with well taken care of and freshly pedicured feet. Now, in my opinion, honesty must work both ways, if you are talking to someone with out reviews be aware that beauty is in the eye of the beholder. However, if you are talking with a lady who has positive reviews you are more likely to receive a fair truth. This positively reviewed lady would not want to misinform and potentially hurt her high status. Asking for pics may be an intrusive start to setting up a meeting, start by simply asking. I hope this helps!
Best,
Alyssa
