Why Do Sandals Make a Suction Noise?

Even the best-made sandals can make suction noises from time to time, depending on materials, foot shape, and how (or where) you wear them. So, if you’re worried that it’s a sign of poor-quality craftsmanship, you can put your mind at rest.

The suction noise usually happens when air gets trapped between your foot and the insole of your sandal, especially if the surface is smooth and your foot is slightly damp, for example, after a long day or in hot weather.

Here are the most common culprits for sandal suction:

Trapped moisture: sweat or water between your foot and the sandal can create a seal that leads to the squelch sound as you walk

Smooth insoles: leather or synthetic footbeds with glossy finishes are more likely to cause suction sounds, especially when worn barefoot

Loose-fitting sandals: if your sandal doesn’t stay snug against your foot, air can enter and escape with each step, making the dreaded noise

Wear and tear: over time, previously non-squeaky insoles can flatten or develop a sheen that increases suction

Noisy sandals are most common in summer when feet get warmer and shoes are worn without socks. Humid conditions, post-swim feet, or recently moisturised skin can all increase the likelihood of suction forming between your foot and the sandal.

You may also be surprised to know that the surface you walk on plays a role: tiles, polished wood, or stone floors are prone to amplify sound more than carpet or grass. So, if you develop a rogue sandal while you’re out and about, try to walk on something soft until you can address the issue.

Methods on How to Stop Sandal Suction Noise

Here are seven reliable ways to reduce sandal suction noise. These are quick, affordable, and easy to try at home, meaning you can most likely get your favourite pair back in action in no time.

1. Apply Baby Powder or Cornstarch

Baby powder or cornstarch are classic fixes for friction and moisture, and they are also great at absorbing sweat and reducing the sticky contact between your foot and the sandal.

This method works especially well on smooth leather or synthetic footbeds - just dust a small amount onto the insole and reapply as needed on warm days. Be mindful not to use too much, however, as this can create an unpleasant residue.

2. Use Foot or Anti-Chafing Balm

For a less messy alternative to powder, use a clear foot balm or anti-chafing stick to create a silky barrier between your skin and the sandal, reducing the suction effect.

Apply a small amount of balm to areas where your foot meets the arch or ball of the sandal. Look for formulas designed for long-lasting wear that won’t leave marks.

3. Insert a Thin Insole or Footbed

A lightweight insole can break the air seal that causes suction, while also adding extra comfort. Look for gel, foam, or suede insoles that are designed to be low-profile, so they don’t interfere with how the sandal fits.

4. Lightly Scuff the Insole Surface

If your sandals have a very smooth footbed, you can gently rough it up to help reduce suction. Use sandpaper or a nail file to carefully scuff the area under the ball or heel of the foot where contact is strongest. This adds a subtle texture that interrupts the seal without disrupting the comfort of your sandal. We recommend testing a small patch first to avoid damage.

5. Use Dry Wipes or Tissues

For a temporary fix on the go, fold a tissue or a dry wipe and place it under your foot. This helps to absorb moisture and prevent the sticky contact that leads to the suction sound.

While this isn’t a long-term solution, it is a quick and easy way to prevent distracting, potentially embarrassing sounds while out and about.

6. Ensure Your Sandals Fit Properly

Ill-fitting sandals are much more prone to suction noises. If your sandals have adjustable straps, make sure they’re snug enough to hold your foot in place without causing pressure. And if you find your foot still slides around as you walk, you may need to opt for a smaller size.

7. Rotate Pairs or Choose Different Materials

If a particular pair remains noisy despite your best efforts, it might be because of the construction or material. Some styles, especially those with synthetic insoles, are more prone to suction. Suede, cork, or padded footbeds are often quieter.

It’s also helpful to rotate your sandals throughout the week, which gives each pair time to dry out and retain its shape – the perfect excuse to expand your collection!

Can Suction Noise Be Prevented Altogether?

While the methods above can fix suction noise once it starts, there are also some proactive steps you can take to prevent it altogether. Choosing sandals with the right materials is a great place to start. Footbeds made from suede, cork, or textured leather tend to be less prone to suction than glossy or smooth synthetic finishes. A slightly contoured insole can also reduce full-surface contact with your foot, helping air to circulate more freely.

Size is just as important: sandals that fit too loosely are more likely to allow air to move in and out, which increases the likelihood of noise. Look for a pair with adjustable straps to customise the fit across different parts of your foot.

Also consider the environment: if you're regularly walking on tiled floors or in humid weather, on holiday, for example, it’s probably worth having a backup pair made from more breathable or padded materials.

Step Out in Comfort and Quiet

Sandal suction noise doesn’t have to be a lingering part of your summer walk. With the tips above, you should be able to nip it in the bud.
