Good luck - I hope this works for you. I purchased the Pedegg and that little product is the best thing since sliced bread!! I was amazed at how well it worked and how soft and smooth my feet were after I used it. And it was onlt $9.99!!
I know how dry my skin seems to get in the Winter - seems I go through lotion by the gallon. I do the same thing you're doing - lots of lotion and then socks. It seems to help.
Have fun with your new foot spa!
