I just bought my first pair of Church's, a really nice looking polished binder shoe from a new line called the City line. Sleek looking design, apparently on a brand new last. HOWEVER, I'm getting paranoid from all the posts here that Church's uses cheap leather. I get the suspicion that some people aren't sure if polished binder actually is corrected grain or not and what that means for the quality. So...... (1) Is this good quality or low quality leather? (2) Are they corrected grain? Thank you!
