Aloha Gtto,
May I suggest you try a pair of
Mor-Fins? They are the smoothest, most comfortable fins I've ever worn and I've been on over 7,000 dives. They don't twist your feet on the side to side action and they won't get tighter and tighter on your foot as you kick like the Force Fins do on me. They are reasonably priced, easy to travel with and are pretty much indestructible with a very simple, reliable, easy to adjust foot strap.
Mor-Fins come in sizes from small to XXL. I would say an XL should work well on a size 11-12 with bootie, L for 9-10, M for 7-8. I was wearing XXL's with my size 11 boots for a while just to see if the bigger size gave me better performance. Had a little extra room but they felt great, the increase in performance was negligible to me. (They are 5% bigger than the XL's.) I think you could almost buy two pairs of Mor-Fins for the price of one pair of FF's.
Not many people have tried Mor-Fins yet. They're still quite new on the SCUBA scene. They're simply the most comfortable, easiest kicking fins I've ever used and I've tried LOTS of different brands and styles in my 26 years of diving, including splits, FF, Jets, Twin Jets, Rockets, Rondines, Quattros, Turbo-Flex, Sea Wing Guerrillas, Manta Rays, Bio-Fins, Appollo's, etc., etc. Oh, and yes, they work really good on the surface...no slapping...unless you want to!
By the way, if you must make a long surface swim, I suggest doing it on your back most of the way, only turning over to look below when you need to. This is the most efficient way to go. I specialize in shore diving and have logged over 3,500 beach/shore dives here on Maui. I don and doff the fins when I'm chest deep. There's not usually a need to walk in and out with the fins on here even though we do get some big surf some days....after all it is Hawaii! I see no reason to walk around with them on but if you must, the Mor-Fins are easy to walk in too.
Try a pair. I'll bet you end up loving them. I just sold two pairs last night to a couple who was diving with me for five dives over the weekend. They had they're own fins for the first dive, then tried mine. Needless to say, their old fins are going in a yard sale when they get home!
Sorry to all the other fin manufacturers out there but in my opinion, Mor-Fins are the Superior Fin Design on the market today.
All the best with your decision!
Aloha,
