I've been watching for a couple weeks, but unable to find some shell wingtips or longwings in Ravello. I see Leffot and LS have had them in the past, but are long since sold out. I'm guessing because its winter time they're focusing on the boots, how likely is it somebody will get some come springtime?
If you're looking for a pair right now, it's likely you won't find any Ravello wingtips. If you're fine with longwings, have you checked Alden of Carmel, or called some of the other Alden retailers (Alden of Madison, Alden of DC, Sky Valet, etc.)? I know Adam at AoC has several pairs, it just depends on the size that you are looking for.
