i was diagnosed with a plantars wart Dr. put dry ice on it

i was diagnosed with a plantars wart, Dr. put dry ice on it
It was still there after years of not talking to Dr. about it any more.
But i got sick and have been home bound for 2 years a very small part of being home bound was of plantar's warts pain
So i took it upon myself to treat it my self hehehehehe !!!!!
What i have been doing is keeping my feet moist all day long with plastic wrap and Vaseline for the last 3 months it did not start to relieve for the first month
IT IS WORKING the pain and the warts are subsiding
MY QUESTION IS ?????
how do i keep my feet moist all day in a working environment,,,,, by trade i am on my feet all day
The plastic wont let my feet breath and the plastic will stretch and fall apart in my shoes
i need the answer to keeping feet moist all day
Thanks for any answers
