Things You’ll Need:
* a pair of socks (calf-length, at least) that you can spare
* 1 pound box of baking soda
Pour 1/2 of a 1 pound box of baking soda in each one of the spare socks. Tie the socks together with a loose knot, leaving enough length so each sock will fit into each shoe.
Push one sock into the right shoe and the other sock into the left shoe. Set the shoes aside where you usually keep them.
The next day, remove the pair of baking soda socks and set them aside to use again.
