My long flat feet are US size 16 and fit very comfortably in Omer Stingray footpockets, size 46/48, when wearing 3mm Body Glove neoprene socks. I've been using them for nearly a year now matched with my 5 year old DiveR blades. I've enjoyed many many hours diving with those fins, but after joining this forum a few days ago and reading all the Pathos/Pursuit testimonials... I'm tempted.
If any of you have firsthand knowledge to compare the fit of Size 46/48 Stingray to Pathos (3rd Gen) I'd appreciate you writing about it. I should probably just go ahead and order one footpocket from Dan to try it on myself.
