Reef - have worn the same pair for 3 WDW and 1 DLR trips

Mine are a discontinued model but the salespeople that I have asked said that the Sandy is the closest to mine.
Last surf shop I went to (in Puerto Rico) told me mine are the holy grail of Reef flips. I ask in every surf/beach shop I go to (and that has been a lot of them!) about my style but no go

Don't understand why companies change their "formula" when people love them so much!
I tried the Tevas but they fit so narrow, I was wondering why so many people love them. Then I read that this is the new style - they went right back. Right now I have some Flojos that look nice and are comfy but I would not try them all day in the parks.
Have you tried FitFlops? I wore mine on alternate days with my Reefs on the DLR trip and they are super comfortable. I also have a pair of Birkenstocks but not sure how everyone thinks they are comfortable. I've been trying to break them in for about 3 weeks now
