Have you noticed a small rough spot on the bottom of your foot? Maybe it feels slightly tender when you walk, or like you’re stepping on a tiny pebble.
As winter settles in and you’re spending more time indoors, the change in weather may begin to affect your foot health.
The link between weather, humidity and warts is something many people don’t immediately consider. However, seasonal changes in indoor environments may create conditions that make plantar warts more likely to develop.
In this article, we explore how humidity and seasonal conditions may influence the development of plantar warts, the signs to watch for, and how professional foot care may help.

A Closer Look at Plantar Warts
Plantar warts are small growths that develop on the soles of the feet due to infection with certain strains of the human papillomavirus (HPV). The virus enters the skin through tiny cuts or abrasions, which may allow it to infect the outer layer of skin.
Plantar warts are quite common. According to the Canadian Skin Patient Alliance, warts affect roughly 7 to 12% of the population, with children and young adults experiencing them more frequently due to higher exposure in shared environments like schools, pools, and sports facilities.
Although plantar warts are generally not considered dangerous, they may cause discomfort when walking or standing, particularly if they develop in areas exposed to pressure. Some people may also notice the wart spreading or additional warts appearing nearby over time.
How Plantar Warts Develop on the Feet
The virus responsible for plantar warts tends to thrive in warm, moist environments, which may increase the likelihood of transmission in certain settings.
You may be more likely to encounter HPV in places such as:
- Public swimming pools
- Communal showers
- Locker rooms or gym change areas
- Shared flooring in recreational facilities
While exposure to the virus does not always lead to wart formation, factors such as skin damage, moisture, or prolonged pressure on the feet may increase the likelihood that the virus enters the skin and begins to develop into a wart.
Why Winter or Summer Conditions may Increase Wart Risk
The seasons bring several environmental changes that may affect the health of your skin, including the skin on your feet. While plantar warts may develop at any time of year, certain seasonal factors may create conditions that allow the virus responsible for warts to spread more easily.
Changes in Outdoor Humidity
During the warmer months, the humid weather can cause increased sweating which allows the HPV virus to survive for longer periods of time on the skin, and make wart treatments more difficult. You may also find yourself more active in sports and exercise, spending more time in occlusive footwear such as soccer cleats or running shoes, also contributing to increased sweating.
Increased Time in Heavy Footwear
Winter weather often means spending more time indoors, or wearing heavy and waterproof boots or shoes. These environments are often warm and humid, which may also create conditions where viruses can spread more easily.
While these factors do not guarantee that plantar warts will develop, they may increase the chances of exposure. Being aware of these seasonal influences may help you recognize early symptoms and take steps to protect your foot health.
Signs You may Have a Plantar Wart
Plantar warts may sometimes be mistaken for other common foot concerns, such as corns or calluses.
While plantar warts are generally not considered dangerous, they may become uncomfortable or spread if left untreated. Recognizing the signs early may help you decide when it could be helpful to seek professional foot care.
Common signs that may indicate a plantar wart include:
- A small, rough growth on the sole of the foot
- Tiny black dots within the lesion
- Pain or tenderness when standing or walking
- A lesion that interrupts natural skin lines
- A growth that persists or spreads
If you notice a persistent or painful growth on the bottom of your foot, a professional foot assessment may help determine the cause and discuss appropriate treatment options.
How Professional Foot Care may Help Treat Plantar Warts
A qualified foot care professional may examine the affected area, confirm whether the lesion is a wart, and recommend treatments based on your individual needs.
While not all warts require treatment, some people seek professional care when the wart interferes with walking, spreads, or does not respond to over-the-counter options.
Professional Assessment
An assessment may help determine whether the lesion is a plantar wart or another condition, such as a corn or callus. Because these conditions may appear similarly, a proper evaluation may help determine the most appropriate treatment approach.
During an assessment, a foot care professional may:
- Examine the lesion and surrounding skin
- Check for signs typical of plantar warts
- Discuss symptoms such as pain when standing or walking
- Review any previous treatments you may have tried
Targeted Treatment Options
If treatment is recommended, several approaches may be used depending on the wart’s size, location, and how long it has been present.
Possible treatment options may include:
- Debridement: Carefully reducing thickened skin over the wart may help relieve pressure and allow treatments to reach the affected area.
- Topical Treatments: Certain medications may be applied to help break down wart tissue over time.
- Surgical Treatments: For more urgent or painful cases, it may be best to remove the lesion entirely.
Managing Discomfort and Spread
In addition to treating the wart itself, professional care may also help reduce pressure on the affected area and provide guidance on preventing the virus from spreading to other areas of the foot or to other people.
This may include footwear recommendations, protective padding, or strategies to help reduce moisture and skin irritation around the wart.
Supporting Healthy Feet Year-Round
During temperature extremes, changes in indoor humidity, colder or warmer weather, and footwear may affect the skin on your feet and create conditions where viruses spread more easily.
Paying attention to changes in your feet and maintaining good foot care habits throughout the colder months may help reduce the risk of developing foot concerns.
If you notice a persistent growth, discomfort when walking, or changes in the skin on your feet, a professional assessment may help identify the cause and discuss appropriate treatment options.
