Yes. Absolutely call it off. In fact, not only should you call it off, but you should alert every Shadchan in town about this person.
You are *absolutely* correct to discern that the color of a person’s socks is an indicator of their level of Yiras Shamayim.

P.S. — Personally, I’m worried about your level of Yiras Shamayim too. You used two question marks at the end of your post instead of one. Clearly there is a chisaron in your emunah and Yiras Shamayim that must be addressed. After all, you didn’t think HKBH could make your point clear to us readers with a single question mark? You felt the need to add another?
