How can I gain rid of my corns lastingly?

Hi everyone, can someone out there please let somebody know me how to get rid of my corns? I'm within real estate and when I'm showing houses, they are newly killing me..not fitting for business..Thanks!!How can I gain rid of my corns lastingly?
Unfortunately if you're anything like me you're usually wearing 2 - 4 inch heal that point in the front. I'm also surrounded by Real Estate and walking around all light of day in shoes that are not flip flops or sneakers (on some people) will enjoy effect.
I go contained by weekly to my nail spa and hold almost a 2 hour foot pedicure that soaks my feet and consequently they wrap it with hot wax and they chafe them etc, etc. That will put a dent in your wallet (it's $50.00) but it definately help them out. I also have a foot spa at home and if I'm sitting down surrounded by my living room watching tv i"ll soak my feet and after I harass my husband to rub them near cream. I also where (around the house) really fluffy behaviour slippers. Good luck!
GET SHOES THAT FIT PROPERLY !
At night, put castor grease on them, wrap with plastic wrap, and consequently put on white cotton socks so nothing get messed from the oil.
