Taking care of your feet is important when you are hiking and carrying a backpack. Sometimes the feet can smell so bad after a day of activities that removing your shoes can be embarrassing.
There are several tricks that you can use to completely eliminate foot small.
First, when hiking, stop every hour or two and change your socks. Tie the wet socks that you just took off to your backpack so they can air out.
You should let your shoes air out at night. You can always bring a second pair of shoes.
Wash your feet every day.
Choose boots or shoes that are ventilated. Many times smelly feet are the result of gym shoes that do not have any ventilation.
If you have athletes feet already, there are some tricks to eliminate that. Fill a bowl with rubbing alcohol or similar product and soak your feet.
The military uses a special material for their socks (merino wool and fortified with nylon). You can purchase these on Amazon or the Internet.
