Managing Smelly Feet: Causes, Prevention, and Effective Treatments Gotham Footcare

Smelly feet, often referred to as bromhidrosis, is an embarrassing yet common issue that can affect anyone. Whether it’s due to sweat, bacteria, fungus, or even the shoes you wear, addressing the underlying causes can help you manage and prevent foot odor. Dr. Miguel Cunha, founder of Gotham Footcare and an experienced foot and ankle surgeon, offers insights into the causes of smelly feet and shares practical tips on how to keep them fresh and odor-free.

Meet Dr. Miguel Cunha and Gotham Footcare

Dr. Miguel Cunha is a board-certified foot and ankle surgeon who founded Gotham Footcare, a leading podiatry practice in Manhattan. With over a decade of experience, Dr. Cunha specializes in treating foot and ankle conditions, including dermatological issues, sports injuries, and complex reconstructive surgeries. His expertise has made him a trusted name in foot health care, and his practice focuses on helping patients maintain healthy feet through personalized care.

What Causes Smelly Feet?

There are several potential causes of foot odor, ranging from natural body functions to more serious underlying conditions. Dr. Cunha explains some of the most common culprits behind smelly feet:

• Bacteria: “Bacteria feed on dead skin cells and oils from your skin. As bacteria colonies grow, they release organic acids that result in unpleasant odors,” Dr. Cunha explains. Certain bacteria, like Kytococcus sedentarius, produce sulfur compounds, which can create a strong rotten egg smell.
• Fungus (Athlete’s Foot): Athlete’s foot is a fungal infection that often develops between the toes or on the soles of the feet. It can cause scaling, itching, and sometimes cracking, which can lead to foot odor. Dr. Cunha recommends keeping your feet dry and disinfecting shoes regularly to prevent fungal infections.
• Nail Fungus: Nail fungus can begin as an infection on the skin before penetrating deeper into the nail, causing it to discolor, thicken, and crumble. This condition is not only unsightly but also a significant contributor to foot odor.
• Sweat (Hyperhidrosis): Excessive sweating, known as hyperhidrosis, is another common cause of smelly feet. “People with hyperhidrosis sweat excessively, leading to moisture buildup that creates an ideal environment for bacteria and fungi to thrive,” Dr. Cunha notes.
• Genetics: Hyperhidrosis can be hereditary. If you have family members who struggle with excessive sweating, you might be genetically predisposed to this condition.
• Medical Conditions: Certain medical conditions, such as diabetes, thyroid disorders, and menopause, can contribute to excessive sweating and foot odor. Additionally, medications and infections may trigger secondary hyperhidrosis, making it difficult to control foot moisture.

How Can You Manage Smelly Feet?

Fortunately, there are several ways to prevent and manage foot odor by addressing its root causes. Here are Dr. Cunha’s expert recommendations:

• Wash Your Feet Regularly: Dr. Cunha advises, “Make it a habit to wash your feet daily with antibacterial soap and thoroughly dry them, especially between the toes, to reduce moisture and prevent bacterial growth.”
• Use Antifungal and Deodorizing Products: Applying antifungal sprays, powders, or foot deodorants can help keep feet dry and prevent infections. “Cornstarch, antifungal powders, or even antiperspirant deodorant can help absorb sweat and protect against foot odor,” says Dr. Cunha.
• Keep Your Toenails Trimmed: Long toenails can harbor bacteria and fungi. Regularly trimming your nails will minimize the buildup of microorganisms that contribute to bad smells.
• Change Your Socks Regularly: Socks made from moisture-wicking materials like nylon or merino wool help keep feet dry. “Change your socks daily, or even twice a day if necessary, to keep feet fresh,” advises Dr. Cunha.
• Choose Breathable Shoes: Wearing shoes made of breathable materials, such as leather or canvas, can help prevent foot odor by allowing air circulation. Avoid wearing shoes made of plastic or other non-breathable materials that trap moisture.
• Disinfect Your Shoes: “Spray Lysol or other disinfectants inside your shoes regularly to kill bacteria and fungi that cause odor,” Dr. Cunha recommends. Rotating your shoes and giving them time to air out between wears can also help.
• Adjust Your Diet: Certain foods, such as garlic, onions, and high-sulfur foods, can contribute to body odor, including foot odor. Reducing the intake of processed carbohydrates and incorporating a balanced diet can help manage smelly feet.

Additional Tips for Managing Foot Odor

Dr. Cunha emphasizes the importance of using conservative at-home treatments and seeking medical help for more severe cases of smelly feet:

• Weekly Foot Soaks: “At-home foot soaks with baking soda, tea tree oil, or warm water can be helpful for reducing foot odor,” says Dr. Cunha. These natural remedies help neutralize odor-causing bacteria and soothe the skin.
• Medical Treatments for Severe Cases: For individuals suffering from hyperhidrosis, Dr. Cunha suggests medical interventions such as prescription-strength antiperspirants, Botox injections to reduce sweating, or even iontophoresis, a treatment that uses electrical currents to decrease sweat production.
• Avoid Overuse of Harsh Chemicals: While disinfectants like Lysol can be effective for cleaning shoes, Dr. Cunha advises against applying harsh chemicals directly to the skin. These products can irritate the skin and exacerbate foot problems.

Products to Help Control Foot Odor

If you’re dealing with persistent foot odor, there are several products Dr. Cunha recommends to help address the issue:

• Lotrimin Antifungal Foot Powder: Effective for combating athlete’s foot and other fungal infections.
• Arm & Hammer Invisible Foot Spray Antiperspirant: Provides odor protection while keeping your feet dry.
• Tea Tree Oil Foot Soak: A natural remedy for reducing odor and fighting fungal infections.
• Lysol Spray: Use it to disinfect shoes and prevent the growth of odor-causing bacteria and fungi.

For additional protection, Dr. Cunha also suggests using moisture-wicking socks made from materials like polyester or merino wool, which help keep feet dry and comfortable throughout the day.

What Not to Do

While many treatments are effective in controlling foot odor, Dr. Cunha warns against certain practices:

• Avoid Applying Disinfectants to the Skin: “Do not use products like Lysol directly on your skin,” Dr. Cunha advises. These chemicals can irritate the skin and lead to further issues.
• Wearing Non-Breathable Shoes: Avoid shoes made of materials that trap moisture, such as plastic or synthetic leather. These can worsen foot odor and contribute to fungal infections.

Dealing with Smelly Shoes

Smelly feet often lead to smelly shoes, creating a cycle of odor that can be difficult to break. To prevent your shoes from contributing to the problem, Dr. Cunha recommends:

• Using Deodorizing Powders or Sprays: Applying foot powders or sprays like Lotrimin or Arm & Hammer to your shoes can help absorb moisture and neutralize odor.
• Choosing Breathable Materials: Opt for shoes made of breathable materials like leather or canvas to allow airflow and reduce moisture buildup.
• Swapping Insoles: Replace your shoe insoles regularly, especially if they become worn out or develop an odor.
• Rotating Your Shoes: Give your shoes time to air out by rotating them and avoiding wearing the same pair every day.
