Foot odor develops when sweat is trapped inside shoes or socks along with acid-producing bacteria. Prolonged use of foot creams can be a factor, too. People with the problem (or their loved ones) might consider talking to a doctor about prescription-strength aluminum chloride hexahydrate (20 percent solution). In the meantime, and assuming one does not have any open foot sores, soaking feet for 20-30 minutes every day in one of the following solutions may also help clear the air.

• Vinegar: Mix one part vinegar with two parts warm water.
• Strong tea: Boil four tea bags in one quart of water, then add two quarts cool water.
• Salt: Add ½ cup of kosher or sea salt to one quart water. Don’t rinse. Pat dry only.
