I've been wearing too many Sperrys lately. Sizing seems very consistent across different Sperry styles. I bought brown/brown from Revain. FYI, I don't know if nubuck holds up well in the rain so I only wear them on sunny days. EDIT: The stitching came undone in the toe box of both shoes after 2 months of minimal wear for the Brown Buck/Brown colorway. My other Sperrys have lasted much longer.
