Treat your feet
Especially awesome after a nice, hot bath; give your feet a good slathering of Chocolate Body Butter (and a little massage to boot) then put on sock and go to bed. The socks will retain the moisture, the body butter will soak in overnight and leave your feet softer in the morning.
The ingredients of this body butter are anti-fungal and anti-bacterial. This is good news for smelly feet as strong foot oder is often caused by an excess of bacteria. Additionally, coconut oil has a mild antiperspirant effect so use on the feet can cut down on the amount of sweat they give off.
Treat your feet every night for a week and see if they don't feel softer and smell better.
