Is he diabetic?? if so type 1 or type 2 and what meds is he taking??? hard to give you advice if we don't know more about hubby!
He has type 2 and on oral med's only. He could change his socks 2-3 times a day his feet get so wet. He has tried all the feet sprays and powders and nothing seems to help. I have gotten him special diabetic socks they do not help, I also got him speical moisture wicking socks they do not help.
