What You'll Learn

Choose breathable materials like TPU over PVC
Plastic shoes, such as clear plastic heels, can fog up due to the buildup of condensation inside the shoe. One way to prevent this is to choose shoes made from breathable materials. When it comes to plastics, Thermoplastic Polyurethane (TPU) is a more breathable option compared to Polyvinyl Chloride (PVC).
TPU is a highly elastic and versatile polymer that combines the advantages of rubber and plastic. It offers excellent abrasion resistance, toughness, and ageing resistance. TPU is also known for its superior durability and performance, making it ideal for products that require high durability, such as automotive parts and medical devices. In addition, TPU is more environmentally friendly than PVC as it is recyclable and free of harmful chlorine-based additives.
On the other hand, PVC is one of the most widely used plastics globally due to its low cost and ease of processing. However, it is prone to cracking under prolonged stress or in extreme environments. PVC also has limited aesthetic options and is challenging to recycle due to its chlorine content.
When it comes to footwear, choosing shoes made from TPU can help reduce the fogging effect as the material is more breathable and better at wicking away moisture. TPU is also gentler on the skin and less likely to cause skin irritation or other health issues associated with PVC, such as migraines and congestion.
Additionally, TPU shoes may be more durable and long-lasting, especially if exposed to harsh conditions or prolonged use. While the upfront cost of TPU may be higher, its exceptional performance and longevity can result in long-term savings. Therefore, when purchasing plastic shoes, opting for those made from TPU can help prevent fogging and provide a more sustainable and comfortable option.

Wear socks to wick away moisture
One of the primary causes of fogging in plastic shoes is the presence of moisture and temperature differences between the inside and outside of the shoe. When your feet sweat, moisture can become trapped inside, leading to condensation and fogging. To prevent this, wearing socks or stockings can help wick away moisture and reduce the likelihood of fogging.
Wicking is the process of drawing moisture away from the skin and evaporating it, helping to keep your feet dry. By wearing socks, you can absorb and wick away the sweat from your feet before it has a chance to evaporate and fog up your plastic shoes.
There are a variety of socks designed specifically for wicking moisture, often made with synthetic materials such as polyester, nylon, or spandex. These materials are engineered to pull moisture away from the skin, keeping your feet dry and comfortable. Cotton socks can also be effective, as cotton is a natural fibre that absorbs moisture well.
When choosing socks to prevent fogging in your plastic shoes, consider the type of sock and the material it is made from. Thin, lightweight socks made with moisture-wicking materials will help keep your feet cool and dry, while thicker socks may provide added warmth and absorption. It is also important to ensure that your socks fit snugly and cover the entire foot, providing a barrier between your skin and the shoe.
Additionally, you can further enhance the moisture-wicking properties of your socks by maintaining good foot hygiene. Keep your feet clean and dry, and consider using foot powder or antiperspirant to reduce sweating and moisture buildup. By combining proper foot care with the right choice of socks, you can effectively wick away moisture and prevent fogging in your plastic shoes.

Use anti-fog spray
If you want to prevent your plastic shoes from fogging up, one solution is to use an anti-fog spray. These sprays work by reducing the surface tension of the plastic, causing the water droplets to "slip" down the surface of the shoe rather than sticking and forming fog.
There are a variety of anti-fog sprays available on the market, including those designed for swim goggles, glasses, and even motorcycle helmets. When selecting an anti-fog spray, it is important to choose one that will stick well to the surface of your shoes and provide long-lasting protection. Be sure to read reviews and follow any directions provided by the manufacturer.
Before applying the anti-fog spray, it is crucial to prepare the surface of your shoes. Fog forms when there is a temperature difference between the inside and outside of the shoe, leading to the creation of water droplets that attach themselves to the plastic. Therefore, you should start by cleaning the inside of your shoes with a non-abrasive cleaner, such as a mixture of vinegar and water. Avoid using your fingers to clean the surface, as this can leave behind residues and body oils that provide attachment points for fog droplets.
Once the shoes are clean, rinse them with hot water. Then, apply the anti-fog spray evenly to the inside surface of the shoe. You may need to move the shoe around to ensure a complete coating. Finally, rinse the solution from the shoe with water.
It is worth noting that anti-fog sprays may not provide permanent results, especially in enclosed shoes with limited airflow. For best results, some products recommend reapplying the spray before each wear. Additionally, while anti-fog sprays can help reduce fogging, they may not completely eliminate it, especially in very humid environments.

Avoid storing in damp conditions
One of the primary causes of fogging in plastic shoes is the presence of moisture and temperature differences between the inside and outside of the shoe. When your feet sweat or when the shoes are exposed to humid environments, moisture can become trapped inside, leading to condensation and fogging. Therefore, it is important to avoid storing plastic shoes in damp or humid conditions to prevent fogging.
Damp conditions can include environments with high humidity or places with poor ventilation, such as enclosed spaces or areas with limited airflow. If you live in an area with high humidity, consider using a dehumidifier to help reduce the moisture content in the air. Additionally, choose a storage area with proper ventilation to ensure adequate airflow around the shoes.
Another factor to consider is the material of the shoes themselves. Some materials, like PVC and certain types of plastic, are more prone to fogging due to their inability to breathe and release moisture effectively. These materials can trap moisture inside, leading to condensation and fogging. Therefore, when choosing plastic shoes, opt for materials that are breathable and allow for proper air circulation. TPU-clear shoes, for example, offer better air circulation and moisture release, making them less likely to fog up.
It is also important to clean your plastic shoes properly. Using improper cleaning methods or products can leave residue on the shoes, which can attract moisture and make them more susceptible to fogging. Choose cleaning products that are suitable for plastic shoes and ensure that they are thoroughly dried before storing them.
By avoiding damp and humid conditions, selecting the right materials, and maintaining proper cleaning practices, you can help prevent fogging in your plastic shoes and keep them looking their best.
