Barrie Boots = 8.5D (pretty perfect)
Barrie Shoes = 8.5D (slightly loose in heel)
Plaza Boots = 9D (oddly, maybe slightly roomy overall)
LHS = ?? (I'm thinking 8.5C especially considering I'd like to wear them sockless much of the time)
Sadly, I don't really have the option of trying any on, so your advice would be appreciated even though I know sizing is extra difficult for loafers.
8.5C should work.
