Shopper Couldn't see size chart, I am shoe size 13?
LeisurePro S These will all probably be too small. If you don't have an exceptionally wide foot, you might be able to squeeze comfortably into the 10-11's, but I would look at some fins that come in larger sizes (the rule of thumb for closed heel fins is to order 1/2-1 size down from your shoe size for a snug fit).
