Wondering what causes your crocs to shrink?

Crocs are famous for their unique design and durability. High temperatures shrink the croslite material. That’s why your shoe size decreases when you put them in direct sunlight.

Shrinking of crocs shoes is normal, as it is also mentioned on the official crocs website to avoid storing them in intense heat.

In this article, I will explain why your crocs shrink and some techniques to unshrink them. Without taking much time, let’s dive in!

Reasons for Shrinking Crocs

High heat is the main reason to shrink crocs. The following factors can also result in shrinking your charming crocs shoes.

  • Exposure to high temperature
  • Placing them in a hot car
  • Putting near heater
  • Washing them in a dishwasher

Exposure to High Temperature

Excessive heat is more likely to change the shape and size of your crocs. Croslite material is flexible and delicate to high heat. You might notice that many people place their loose crocs shoes in sunlight to reduce the size of their shoes.

It takes less than 30 minutes to shrink crocs in heat. Hence, it is advisable not to leave your crocs in the sun for a long time. The reason is that it makes them uncomfortable and unwearable.

Placing Them in A Hot Car

People who forget to pick up their crocs from the car and place their car in direct sunlight. Eventually, their car gets hot and shrinks crocs. Avoid placing them in hot places.

I recommend storing your favorite pair of crocs in a cool area to avoid damage.

Putting Near a Heater

It might be a possibility that you have put your adorable crocs near a heater. The heater also produces heat and shrinks them unexpectedly.

This case is rare, but I have seen people whose crocs shrink near a heater. Hard to imagine, but it tells us how important it is to protect your crocs from heat.

Washing Them in A Dishwasher

Cleaning crocs in the dishwasher is not appropriate as it does not completely wipe away the dirt. But still, if you do, keep these things in your mind. When you wash them in a dishwasher, it produces little heat.

This leads to the shrinking of crocs. Instead of benefiting you, it causes damage. The most suitable method to clean crocs by hand, it will not ruin the excellent quality of your cute pair of crocs.

How to Unshrink Crocs?

Let’s discuss each method to unshrink your charming pair of crocs. I have tested all these methods on my crocs, and they did work perfectly.

  • Hot water
  • Tumbler dryer
  • Hair dryer
  • Freezer
  • Oven

Hot Water

Basin, hot water, thick socks, and crocs are required to perform this method.

Firstly, I boiled some water in a bowl and put my crocs separately in a basin. After pouring hot water into the basin, I submerged my crocs fully in water and flipped them to wet each part of them.

Then I waited 30 seconds and placed my white crocs out of the basin. When they were completely cooled, I wore socks and started strolling inside the house to stretch shoes. Repeat this procedure if the desirable shape of crocs is not obtained.

Tumble Dryer

This technique requires two damped towels, a tumble dryer, and thick socks.

First, I set the temperature of the tumble dryer to medium-low heat. Then I placed damped towels and crocs in the machine and started the machine.

After waiting for 10 minutes, I took my crocs out and wore crocs immediately with thick socks.

Hair Dryer

A hairdryer is the safest method than a tumble dryer, as intense heat is not required. I kept the blow dryer away from the crocs to ensure their safety.

When I realized my crocs were warm enough, I wore them instantly to loose crocs shoes.


Heat is not required to perform this method. I filled the plastic bag with water and placed it into shrunk crocs. Then I put my crocs in a freezer for 9 hours.

This method is beneficial to stretch crocs shoes.


Using the oven is not a common technique to unshrink crocs. To avoid damage, I set the temperature to 50-80 degrees centigrade and then placed my crocs in the oven.

After a few minutes, I put them out of the oven and began to walk by wearing the crocs. Don’t forget to take precautions properly. Repeat the procedure if you are not satisfied with the size of the crocs.
