Why Do Crocs Shrink?

Why Do Crocs Shrink

Crocs have been famous for summer footwear for 5-6 years because of their ventilation system. The shoes have ventilation that helps create extra airflow into the shoe. In addition, these holes also help the debris get out.

But why does it shrink? Well, the most common cause of crocs shrinking is heat, and the primary source is the sun. The crocs being under the sun for excessive amounts of time can lead to it shrinking.

How much usually it will shrink is very hard to predict, but in most cases, the longer it is exposed to heat, the more shrunk your crocs will be. For example, being under the sun for 30 minutes may cause minimal shrinking, whereas leaving it under the sun for a couple of hours will shrink for a maximum of two sizes.  

Furthermore, it is not just the sun that may cause your crocs to shrink; leaving it in a hot car or a washing machine can also lead to shrinking. In both of those instances, the temperature rises a lot.

Now that we know what causes crocs to shrink, let us find ways to solve it.

The easiest way to unshrink your croc is to place your croc in a pot of boiling water and soak it for a bit. It is to loosen the material up.

Let’s unshrink your crocs step-by-step now.

  2. Then take them out.

  4. We recommend wearing a few thick socks before putting on the croc. As it has been just taken out of boiling water, without a doubt, it will be very hot, and putting your feet directly inside it will cause severe burns.
  5. Lastly, repeat the process a few times if you don’t see any. In most cases, it took about 4 rounds of this method to unshrink their crocs.

2. Clothes Dryer

It has the same concept as the boiling water method but is a bit more convenient. In this method, too, we introduce high heat to the crocs malleable and make it stretch to its actual size.

So, let’s begin.

  1. Start this method by starting your dryer and setting the temperature to medium-low heat.
  2. Then set its timer to 10 minutes.
  3. Now put your pair of crocs in with two pieces of wet towel and start the dryer. The wet towels will provide the moisture that will help soften the croc’s material. We suggest standing beside the dryer when doing this step to ensure the heat is not too high.
  4. Once 5 minutes pass by, take the crocs out and wear them instantly. Remember to wear thick socks to ensure you don’t burn your feet.
  5. Wear them till they cool off to unshrink your crocs. If they didn’t unshrink as much as you wanted them to, repeat the process for 5 minutes left on the timer.
  6. We also suggest walking around while wearing them to unshrink them even faster.

  5. You may have to repeat this process a lot because the hair dryer’s heat is not drastic enough.

What Material Are Crocs made of?

What Material Are Crocs made of

Typically it is known and said that crocs are made of EVA foam. However, customer service says crocs croslite material isn’t made from EVA Foam. They continued saying they are restricted from disclosing its contents as it is supposedly a proprietary closed-cell resin.

Every style of crocs is made from croslite material, which is fantastic for absorbing resin material to provide maximum cushioning. This material is safe to be worn directly above the skin and can be washed using soap and water.

Furthermore, they contain no latex material and are 100% croslite material. However, some models do contain latex. So avoid those if you are sensitive to latex.

After some research, we also further found that crocs are made of Ethylene-vinyl acetate, which is a copolymer of ethylene and vinyl acetate. Vinyl acetate is the material that builds up about 10-40 percent of the copolymer, while the rest is ethylene.

The result is a polymer, an elastomeric material that is extremely flexible and soft.

Furthermore, it has thermoplastic qualities.

Do Crocs Stretch?

Do Crocs Stretch

Yes, they do stretch and shrink. But the stretch does not occur over time; instead, it can stretch when worn after being exposed to a certain heat level.

The croslite material has very high elasticity and can shrink or stretch under specific situations.

But that does not mean you should change your croc size. Despite being a really flexible material, crocs can hold their shape perfectly for a long time. Only if the conditions mentioned above are met, then only will your crocs shrink or stretch.
