How To Make Crocs Bigger

Most of us come to Crocs searching for footwear with comfort and longevity, but is it still obtainable if the sizing is off?

We have several tips on how to make Crocs bigger, regardless of the reason they end up feeling smaller than they should, and they will fit like a second glove as soon as you are done with them.

Can You Make Crocs Bigger?

The short answer is yes, you can increase the size of Crocs. However, depending on the factors that caused them to be so small in the first place, the effort and time you need to invest might vary greatly.

The first case, also the easier one to solve, is you have somehow ended up with a pair of Crocs smaller than your size. The difference between it and your actual size might be relatively small, and the expansion it needs will be imaginable.

However, another problem people tend to have is that their Crocs shrink under high temperatures.

If you expose them to an extent of 30 Celsius degrees (about 80 Fahrenheit), they are likely to start shrinking after 30 minutes and be reduced to half their size when the extreme heat goes on.

It is much tougher than the first situation, yet you can still save your Crocs with enough care and determination.

How To Make Crocs Bigger?

Expanding a shoe’s size sounds like an impending risk of permanent damage, but you can rest assured with these safe methods.

You won’t need any specialized chemicals or uncommon equipment, so your Crocs won’t be subjected to immense damage.

Soak in hot water

To stretch Crocs with hot water, you will need to prepare the things below.

  • A basin to put your Crocs in, preferably heat-resistant.
  • A cooking pot to boil water.
  • A stove.
  • Kitchen tongs or any stick-shaped items you can use to push the shoes deeper into the water.

How to do:

  1. Fill the cooking pot with water and heat it to the boiling temperature on your stove. The amount of water should be enough to immerse your Crocs when you put them in the basin.
  2. Move boiled water and the Crocs to the basin. Use the tongs to push your shoes down and flip them around until they are completely soaked. Give it 45 – 60 seconds.
  3. After getting your Crocs out of the water, wait for a couple of minutes so they can cool down a bit before putting them on while they are still warm and wet.
  4. Your Crocs are now considered stretched, and you will keep wearing them until they are all cooled and shaped for your feet.

Some tips:

  • If your Crocs aren’t shrinking too much and you simply want to expand them a little, you can wear socks to avoid burns and put the Crocs on right after they are out of the hot water for more efficiency. Socks also add to your foot size.
  • You can repeat the process over and over again until you are satisfied with the result.

Heat with a hairdryer

Make Crocs bigger with a hairdryer

To stretch Crocs with a hair dryer, you will need nothing other than thick socks and a hair dryer.

  1. Keep the hair dryer blowing at the troubled Crocs for a few minutes without pressing the blower against the Crocs. Make sure you heat the shoes evenly and thoroughly.
  2. Once you deem the Crocs warm enough (compared to the warm water that might cause some tingles to your skin), it’s time to wear your socks and put the Crocs on.
  3. Walk around the house as much as possible until the shoes are cooled.

Some tips:

  • You can combine this method with hot water so you won’t have to rely on the hair dryer completely to warm your Crocs.
  • The heat from a hair dryer is usually not intense, you might have to repeat the steps several times and it’s not optional!

Expand with socks

If you need to know how to expand Crocs when you have no equipment ready, we have good news. Your socks are rather reliable for the task.

  1. Wear your thickest pair of socks.
  2. Put two other pairs of medium thickness over them before getting your Crocs on. It might feel a little uncomfortable and tight at first, but shouldn’t be so intense that your blood circulation is cut off.
  3. Walk around your house for at least half an hour so your Crocs can stretch and adjust to your movements as well.
  4. Do it daily for an entire week, and you will notice significant changes.

Some tips:

  • If you feel numb in your feet, you can remove a layer or go for another method.
  • Although this method requires nothing but socks, it will take more time to work.
  • While wearing socks and Crocs, you can get some assistance from a hair dryer, so the stretching will happen sooner and faster.


The idea is strange at first, though if we think about it, Crocs might stretch quite well in the freezer.

Let’s prepare the necessary tools and get to work:

  • Water.
  • Zip bags.
  • Enough space in your freezer.
  • Socks (optional).

How to do:

  1. Fill the bag with water and stuff it into the toe space of your Crocs. Check to ensure the zip is secured so you won’t have any leakage problems.
  2. Leave your Crocs to freeze overnight.
  3. Get the Crocs out of the freezer the next morning and remove the bags while they are still frozen.
  4. After the Crocs thaw a little, put them on while they are still cold and wet. If you don’t have much tolerance for the cold, you can wear socks before walking around indoors until the shoes are back to normal temperatures.

Some tips:

  • If your Crocs shrank unevenly in different spots, you can target them with several water bags
  • If you have difficulties removing the frozen bags, you can run water down the sides of your Crocs to speed the thawing phase a little and loosen the bags.

Despite not being as popular as other methods, the oven is still a good and effective source of heat. What you need to prepare is:

  • A baking sheet.
  • Socks.
  • An oven.

How to do:

  1. Preheat the oven for 5 minutes at 50 – 80 degrees Celsius.
  2. Place your Crocs on the baking sheet and put them in the oven.
  3. The main benefit of using an over is that the heat will be spread evenly inside and outside of the Crocs, hence you only need to put your socks on and wear your shoes to fixate the new size.

Some tips:

  • You need to be very careful and meticulous while using an oven due to the extreme heat. If you go higher than recommended, your Crocs might melt.
  • We don’t recommend repeating this step many times because you might not be able to control the heat.

How Long Does It Take For Crocs To Stretch?

The time your Crocs might take to regain or increase in size after they shrink depends greatly on the method you choose.

If you are in no rush, you can try the sock method, which will take at least a week to show remarkable results. However, it is also the safest way to stretch your Crocs with no possible damage.

The second time-consuming yet safe method is freezing. You will need to wait a whole night for the water bags to solidify and expand the shoes, plus 20 – 30 minutes to walk around with them.

When you have no time to waste, an oven, hair dryer, or boiled water are better choices. It only takes a few minutes to heat the shoes and another half an hour to walk in them until they cool down.

Notices When Stretching Crocs

Stretching Crocs is an effective way to increase the comfort level and simultaneously spare room for a reversible shrinking process.

While it is very possible to make your Crocs bigger than they were or return them to their original size, there are a few things you should keep in mind.

  • If you overstretch your Crocs, your feet might rub against the material too much while you walk, which leads to blisters and scratches.
  • Narrow feet will not benefit from loose Crocs because their heels will constantly pop out.
  • When you wear loose footwear, you are also saying goodbye to sporty activities since you are prone to slips and falls.

Final Words

Learning how to unshrink Crocs or simply increase their size with simple and safe methods will ensure a great fit for your feet and no severe damage to your shoes.

The estimated time for each option isn’t the same, though, hence you might need to choose wisely and save yourself from compromising situations.
