How to Prevent Blisters From Crocs (Without Socks)

You might think comfy slippers like Crocs won’t cause blisters. But do Crocs cause blisters?

Crocs can cause blisters if they are too big or too small. You can wear socks with Crocs to avoid blisters. Another option is using an anti-friction balm for foot protection.

Also, pushing the straps backward on Crocs can help prevent blisters.

In this post, we will show you how to not get blisters from Crocs.

Do Crocs cause blisters?

Crocs can cause blisters if they are fitted poorly. If Crocs’ rubber rubs your feet often, blisters can form, even if they’re worn in. Let’s explore where Crocs cause blisters and why they happen.

Why do Crocs cause blisters?

Crocs can cause blisters if they are not fitted properly.

If Crocs are too big or too tight, they can rub your feet, causing irritation and blisters.

MedicineNet says foot blisters often come from friction, like when feet rub against shoes, such as Crocs.

To avoid blisters, ensure your Crocs fit well.

Where do Crocs cause blisters?

Crocs fit differently than sneakers, leading to different blister-prone areas.

Here are the potential blister areas when wearing Crocs:

  • Inside of the foot, right below the ankle bone (where the strap pivots).
  • Between the big toe and the second toe.
  • Top of the foot.

The most common blister area in Crocs is inside the foot below the ankle, where the strap rubs.

Blisters can form between the big and second toe if Crocs are too tight, pressing the toes together.

Many people face rubbing on the foot’s top. If Crocs touch there, they’re too small.

How to prevent blisters from Crocs

Push the straps back and wear socks to avoid Crocs blisters. Anti-friction balm or Moleskin also prevents blisters.

Here are five tips to avoid Crocs blisters:

1. Buy Crocs that fit your feet perfectly

The best thing you can do to not get blisters from Crocs is to buy the right size.

Don’t buy Crocs that fit like regular shoes. Crocs shouldn’t feel as snug as sneakers.

Crocs should fit loosely, so ideally, your skin won’t touch the rubber and cause friction. Mostly, if your Crocs fit right, you won’t get blisters. If you’re new to Crocs, learn the correct fit.

2. Push the straps backward into “sports mode”

This tip might sound simple, but it effectively prevents painful blisters. Most Crocs have back straps for stability. Push them backward to prevent your feet from sliding and avoid blisters.

For those unfamiliar with Crocs, there are two wearing modes.

The first is “relaxed mode” with straps forward. The second is “sports mode” with straps backward.

In ‘relaxed mode’, Crocs can let your feet slide, causing rubbing that leads to blisters.

In ‘sports mode’, straps pushed back reduce rubbing and secure your feet, preventing blisters.

3. Wear socks with Crocs

Wearing socks with Crocs is a good way to avoid blisters.

Socks protect your feet from the rubber of Crocs, preventing rubbing.

In summer, socks, especially moisture-wicking ones, help prevent foot odor. In winter, they keep your feet warm.

Some believe Crocs look better without socks, but others get blisters without them.

4. Apply “Blister Blocker Balm” before wearing Crocs

If you want to prevent Crocs blisters without socks, apply an anti-friction balm.

The blister blocker balm from Solemates worked well for us.

It effectively blocks strap chafe, heel friction, and toe-rubbing blisters. The Blister Blocker is dermatologist-recommended and non-toxic. It’s made with natural lubricants that care for the skin.

Just apply the balm generously to areas prone to blisters, like the top of your feet and below the ankle bones.

It lasts up to 6 hours, letting you enjoy the beach or Disney World in Crocs without socks or blister worries.

5. Apply Moleskin for extra protection

For safety, always carry some Moleskin with you. Moleskin is a flexible tape that cushions your feet from shoe pressure. It also protects the skin from Crocs’ rubber friction.

Dr. Scholl’s Moleskin Plus Padding Roll:

You can cut Moleskin to any size, and its thin design fits all shoes and conforms to the foot. It is designed to stay on all day, whether you are active or sedentary.

We recommend carrying Moleskin if you plan to walk in your Crocs for long hours. Apply the Moleskin to areas prone to blisters, and you’re set.
