The only three worth buying are the long wing, plain and Yuma - if you could still get it. Maybe a plain loafer too.Cordovan is always going to be fad, as it really is a winter shoe and doesn't bare scrutiny in the summer sun. As I've said before the only one worth buying is the Alden trad saddle oxford, a pre-WWII survivor and collegiate shoe. Mine will out live me, as I only wear them once or twice a year. It's a shoe that is weirdly not of much use at all.
There can be rain issues with Cordovan too, which would limit Winter use.
