Another vote for the Manta Springs.
I have them on all three pairs of fins, they work a treat, and they come in sizes up to XXL. I'm a US size 9 foot, and use the mediums for my wetsuit fins, and the Large for my drysuit fins, so you shouldn't have a problem with the XXL's...

No idea who retails them in the US, but here in Australia, its
Divetek Oz Home page which of course is useless to you, but helpful to anyone else in Australia with the same problem reading the thread.
