Shoes can get smelly easily, especially if you walk a lot throughout the day. Shoe odor can be an embarrassing problem and buying new shoes can be expensive. There are plenty of ways to eliminate the odor in old shoes. You can try washing the shoes, by hand or in the machine. If you're uncomfortable washing your shoes, you can try applying things like dryer sheets and orange peels to remove the scent. To prevent a recurrence, be sure to do things like wear socks and use foot powder to keep odor away.
