Don't leave your Crocs in the car on a hot summer day!

Are you a "hole man" who relies on a pair of hole shoes to walk through the whole summer? These light and casual shoes bring a lot of relaxation to life, but due to the influence of the materials they are made of, they are also prone to various problems in the summer.

Whether it is a sunny day with scorching sun or a rainy season, you need to be extra careful when wearing hole shoes.

Don't leave your Crocs in the car on hot summer days, as they might get deformed due to the heat.

Many Crocs and slippers are made of EVA (ethylene vinyl acetate) foam, a lightweight and flexible material that makes them comfortable to wear.

While EVA shoes have many advantages, they also have some minor drawbacks—for example, poor heat resistance. The softening temperature of the EVA material used in foam shoes is typically between 60°C and 70°C. While the shoes won't completely melt at this temperature, the material's hardness and strength will drop significantly, making them susceptible to deformation or shrinkage.

Summer temperatures of 30-40°C won't affect EVA shoes, but temperatures in places like cars and balconies can reach much higher under direct sunlight. When parked in the sun, the temperature inside a car can be over 20°C higher than outside, a surge high enough to soften and deform Crocs.

On a summer afternoon with strong sunlight, the surface temperature of the road may exceed 60 or even 70 degrees Celsius. Walking on hot roads for a long time may cause the EVA foam sole to deform.Is there any way to save the deformed Crocs?

Some tips mentioned that when the hole shoes are deformed and shrunk, you can soften them again by soaking them in boiling water, blowing hot air, etc., then put on thick socks and step into the shoes while they are still hot, and use your feet to help the shoes stretch and reshape.

This advice does make sense, but even if you heat and reshape the shoes, there is no guarantee that they will return to their original shape. If the operation is not done properly, the deformation will be even worse.

Therefore, it is the safest option to keep your shoes away from high temperatures from the beginning.

During the rainy season in summer, you should pay special attention to safety when wearing hole shoes.

EVA foam shoes are typically made using a "closed-cell foam" process, where each bubble is completely sealed and doesn't connect to each other, preventing water from seeping into the foam. As a result, these shoes are highly waterproof, requiring only a light rinse to clean after wading through water, and they dry quickly. From this perspective, they seem perfectly suited to being rain boots.

However, this type of shoe is not suitable for rainy days: it is more likely to slip when exposed to water. Among common sole materials, EVA foam has poor anti-slip properties. In dry conditions, the anti-slip disadvantage of EVA soles is not obvious, but when the ground is wet, its coefficient of friction decreases significantly, making it more likely for people to fall.

Don't forget to check the soles of your shoes

In addition, EVA foam shoes have another noteworthy disadvantage: their soles are prone to wear and tear.

Among common sole materials such as foam rubber, polyurethane, and EVA, EVA foam has the lowest wear resistance. Therefore, under the same wearing intensity, the soles of hole shoes will always wear more seriously than other shoes.

Wear and tear not only affects the comfort and lifespan of the shoes, but also exacerbates the problem of slipping in rainy days. Wear and tear can cause the anti-slip pattern on the sole to gradually become shallower, or even completely wear away, further reducing the anti-slip properties of the EVA sole.

Therefore, after wearing hole shoes for a long time, be sure to check the wear of the soles and replace them in time if the wear is severe.
