Your feet carry you all around the city, so they really need some pampering from time to time. Here is a simpler recipe which uses a simple, cheap product you have in the kitchen: baking soda.
Baking soda can be used to exfoliate and clean your feet, as well as moisturise your skin. Mix half a cup of baking soda in 4 liters of hot water, then keep your feet in the water for half an hour. In this time, the baking soda will clean your nails, soften the cuticles and calluses, preparing them for the next phase of the treatment.
Take your feet out of the water and massage them with a fat cream, then put on a pair of socks.
This simple treatment you can do weekly keeps your feet smooth and silky and removes odors.
