Tighten Up Your Crocs: A Guide to Making Them Fit Perfectly

Crocs are the epitome of comfort. They’re light, flexible, and airy, perfect for those summertime barbecues or days spent at the beach. However, they tend to loosen up and become too big over time. They can also stretch when exposed to heat. But they can be tightened up again.

If you want to tighten up your crocs, you should know that:

Crocs are made up of a polymer called croslite, which can expand and tighten up when in contact with heat. The best way to tighten Crocs is by heating them; the heat causes the molecules to squeeze and come back into their original shape. This elastic quality helps the shoes fit your feet.

There are many ways to heat Crocs, such as leaving them in the sun, washing them in a dishwasher, or boiling them, but there is a technique required to do it. Excess heat or the wrong method can distort the shape of your shoes permanently and make them impractical. So it is important to follow the right procedure.

In this blog, I will discuss the ways to tighten up your Crocs to make them look brand new again. So read till the end to know how can tighten your crocs to fit your feet perfectly.

How can Crocs Become Loose?

Crocs shoes are unique in their design and comfortable to wear, but they can become loose over time. This can be caused by normal wear and tear or by heat exposure. Crocs are made of a malleable polymer, so if you have left your crocs in the car on a hot summer day, there are chances they might become loose.

Moreover, croslite has lost its original structural integrity by bending and molding the shoes, which can also cause them to become loose. To avoid this, it is recommended to store crocs in a cool, dry place when not in use. Another factor to consider is choosing the right shoe size when buying; if you buy a bigger size, it can be uncomfortable to wear.

It is also important to note that crocs are not suitable for all types of activities, such as extensive running or hiking, as they do not provide enough support for the feet. So it is best to use them for a casual stroll or your funtime summer activities.

What are Crocs Made of?

Crocs are a type of shoe that has become increasingly popular in recent years. They are made from a material called Croslite, which is a closed-cell resin.

This material is lightweight, comfortable, and durable, making it ideal for shoes. This material is also non-marking and odor-resistant, making it ideal for both indoor and outdoor use.

Croslite is also anti-microbial, so it helps to prevent the growth of bacteria. But one of the most redeeming features of this material is its flexibility. The cells can shrink or stretch when exposed to heat.

This makes it ideal for different foot shapes, as it can be adjusted to fit every shoe size. It also leads to problems such as the loosening of your crocs or shrinkage. But the ductile nature makes up for it and saves you from spending more on shoes.

Does this Elasticity Affect their Durability?

As crocs tend to expand and contract easily, many people think that this impacts the overall life of the shoes and makes them less durable. The resin that makes up crocs has a high tensile strength, and it has the elastic strength to endure all these procedures.

Heat and high temperatures cause the molecules to change their original position; they can contract and relax. But that doesn’t impact the overall life of the shoes. As they are designed to be a summer staple, they are made to change the temperature without being deformed.

Boiling Method

Boiling water can quickly shrink your crocs without causing any damage to their color or shape. The heat from the water acts on all sides of the shoes and makes them compact. This aspect is important as unbalanced heat will cause the shoe to look distorted; it will be loose at some points and tight at others.

All you need for this procedure is a pot of boiling water, a pair of tongs, and a rag to clean everything up. These are the steps that you should follow when boiling your crocs:

  1. Take your pot and fill about 3/4th of it with water and let the water boil completely.
  2. Make sure that the water is free of any impurities and the pot is cleaned properly as particles can poke little holes in the surface of the shoes or cause scratches.
  3. When the water starts boiling place your crocs in the pot with the help of tongs. If your crocs don’t fit in the pot together boil them one by one.
  4. Use your tongs to move the shoes around in the water. Let them stay in the water for 2 to 3 minutes.
  5. After that take them out with tongs and let them cool. Remove excess water from them with the help of a rag.
  6. Wear your shoes after they have cooled down and if they still feel a little loose repeat the process.

Dryer Method

Another great way to tighten your crocs is by giving them a spin in the dryer. The hot air from the drier can shrink up your crocs. Be sure to wash and put them on a medium heat setting because high heat can cause the shoes to warp.

This process is relatively easy, as all, you have to do with adjusting the heat setting and set the timer to 10 minutes and put in your crocs. The dryer will do the rest of the job. After 10 minutes take them out and check to see if they fit. You can repeat the process to make them tight.
