I hope you have found a cure for your wet feet,my dad has just about got it cured thanks to a great Chinese ACAPUNCTURE Specialist. He has also help his dragging leg feeling.It did take a few sessions but it worked.GOOD LUCK with your wet feet
cheers
I she on any medications? How about swelling of the leg, foot, and/or ankle?
I have never read of such a problem here, and I have no personal experience, so I have nothing to point to. You didn't mention his primary or family care doctor. Has he discussed it there? Sometimes we need a generalist when the specialists can't "connect the dots".
Wishing a happy outcome and you father getting back to a more active life, that is an important health aid.
