Don’t Bare It All…A Podiatrist’s Perspective

Winter and spring break are just around the corner! Whether you’re heading to a warm beach or a chilly getaway, one important thing to think about is what’s on your feet. As you leave the pool or beach for a quick bathroom break, have you ever noticed someone walking barefoot? Or seen someone strolling through a hotel hallway or lobby without shoes?

When I see this, not only does it raise sanitation concerns, but as a podiatrist, my mind immediately starts racing. Walking barefoot in public areas can expose your feet to infections you definitely don’t want to bring home as a vacation souvenir.

Fungal Infections

Foot and nail fungus are among the most common conditions treated by podiatrists. Athlete’s foot, formally known as tinea pedis, thrives in warm, moist environments. It may appear as circular dry patches, itching, burning, peeling, cracked, or flaky skin. Other signs include redness, scaling, or even small blisters.

Many people mistake this for simple dry skin and try over-the-counter creams. However, what looks like excess skin buildup is often a fungal infection that requires anti-fungal treatment, not moisturizers.

Toenail fungus, or onychomycosis, often begins on the skin and spreads to the nails. Symptoms include discoloration, thickening, and brittle toenails. Since other conditions, such as “runner’s nails,” can look similar, I often recommend a painless toenail biopsy to confirm the diagnosis and tailor the most effective treatment plan.

Viral Infections

Warts are caused by the human papillomavirus (HPV) and thrive on warm, damp surfaces. Swimming pools, locker rooms, communal showers, and gym floors are ideal environments for transmission.

Warts typically appear as rough, grainy bumps with small black dots, often described as a “salt-and-pepper” appearance. They may spread around the main wart, forming what are known as satellite lesions. Unfortunately, warts can be contagious among household members, making regular cleaning of shared surfaces important to help reduce the spread.

Bacterial Infections

I love a good beach vacation, but did you know beach sand can contain 10 to 100 times more fecal bacteria than nearby ocean water? This is especially concerning for individuals with weakened immune systems, autoimmune conditions, or uncontrolled diabetes. These populations are at higher risk for skin infections that can lead to ulcers and, in severe cases, progress to bone or bloodstream infections.

Vacation Foot Health Tips

• Never walk barefoot in public areas
• Air out and clean shoes or footwear between uses
• Rinse your feet after leaving the beach
• Perform daily self-foot checks if you have a weakened immune system
• Always wear flip-flops in hotel showers, locker rooms, and pool areas

Protecting your feet while traveling is simple – and can save you from long-lasting problems once vacation is over. Safe travels and happy, healthy feet!
