Binding Sizes??

I have been searching around for new bindings, and I'm having trouble deciding what size I should go with. I wear a size 11 shoe, and I would say my foot is a little wider than average foot, but I can still wear normal shoes (not nearly as comfy as sandles) Anyways I'm looking at LF Ultras, Exos, Hyperlite Highbacks. What really throws me off is whenever I read up about them the sizing charts are always differnt. Some say XL is 11-13, some say 12-13 some say, large is up to 11, other 10 others 10.5. So I'm right on the verge of either. Any hands on experience tips on what to go with? Also would the sizing chart change from year to year? Thanks!

Some people say to go one size down from what they say, but I don't follow that rule for lf bindings. I can barely get my feet out of LF ultrasucs as it is. I wear a size 11.5-12 and wear an XL ultra suc.

liquid force bindings are not so much size in length, but size of the arch of your foot and the width. LF bindings are known for their smaller width size. Obviously a binding cant be that much longer because then it wouldnt fit on the board. Like i said, LF bindings deal more with the arch not length.
Are you looking at the new 2004 Ultras?
Everyone is saying that they are running very small this year for some reaon. If you wear an 11, go with the XL for sure. However you may want to take a look at the Alpha binding. I have a wide foot too and i hated the Ultras. Try on a set of the alphas, really easy to get into and you can obviously adjust the tightness.
Thats just my 2 cents.
As opposed to what Andrew said above, I'd go one size bigger if you have a wide foot and are on the boarder of sizes. Just coming from personal experiences
