Going barefoot in sandals can have its challenges. Your feet might slide around or get sweaty. Here are our choices of inserts for summer shoes to keep your feet comfortable.

The insoles are a trim-to-fit design with markings on the base you can cut around. Those suitable for flip flops have a pre-cut slit where the toe post sits.



Moisture absorption prevents feet sliding around and keeps them dry and fresh. The upper layer is a soft 100 percent polyester to cushion your feet.

These insoles are designed for dressier sandals and flip flops, and might not adhere to fabric bottomed or spongy footwear.

There are two pairs (four insoles) supplied in each pack, and they’re suitable for men and women’s shoes. Two of the inserts are clear, and the other two are beige.

The company offers a 100 percent money-back guarantee if you’re dissatisfied with these insoles for any reason.

Don’t be surprised if the package you receive tells you they’re ball-of-foot inserts. The company does this when they run out packaging. Rather than delay your order, they use alternate wrapping.

These inserts don’t stick onto cloth or other fiber shoe inners. It seems they only stick to smooth surfaces like leather.

Why Do You Need Insoles in Your Sandals?

People wear insoles in shoes for many different reasons. Maybe there are medical issues, and your feet need support, or perhaps you want more padding.

Whichever is the case here are some factors which influence why you need insoles in your sandals:

  • Sandals are often flat and have little support for arches. This can make your feet feel tired and cause ankles and knees to ache.
  • Comfort is another factor often sacrificed in summer footwear. Insoles designed specifically for sandals can help make them more comfortable.
  • We often wear sandals without socks, and this leaves your feet open to blisters from friction. Some insoles for sandals can help prevent this from happening.
  • Insoles help support arches and relieve pressure on your feet — features you might not find in sandals, especially flip flops.

This video explains why wearing flip flops without support for your feet might be bad for you.


Things to Consider When Buying Sandal Inserts

There are a few important things you might want to consider before buying insoles for your sandals. These include:


1. How Much Support You Need

Insoles for sandals tend to be a lot thinner than traditional ones for shoes and boots. They won’t offer much support for your heels, but they can support arches and the forefoot. Some cushion the whole foot while others target specific areas.


2. What Type of Sandals You Have

You need to choose the right insoles for the type of sandals you have. Most insoles for summer footwear are self-adhesive, making them easy to fit. Decide whether you want small inserts just for your arches or ones that cover the whole footbed.

How to choose Insoles for Sandals and Flip Flops

Some insoles can also be trimmed to fit. You can cut them shorter so they don’t cover the exposed toe area of your sandals. This way they’re not visible when you’re wearing them.

The thickness of the insoles also comes into play. Most for sandals tend to be thin so they shouldn’t take up too much room or make your sandals tight.


Features to Look for in the Best Insoles for Sandals

Let’s look at some things to consider when choosing the best insoles for your sliders, flip flops, wedges, flats, or slingbacks:

  • Insoles won’t stay put in your shoes if they don’t adhere to the footbed in some way. Look for sticky backs or things like Velcro dots.
  • Moisture-wicking. Feet without socks in sandals can get sweaty. Look for materials that help wick moisture away from your feet to keep them dry and fresh.
  • Insoles that incorporate gel tend to be thinner, and it’s a popular choice of material for sandal inserts. It can also have the effect of giving your feet a massage as you walk improving circulation.
  • Arch support. Sandals are often lacking when it comes to arch support. Insoles to support the arches can be small and discreet, but still effective. They help relieve pressure on other parts of your feet by keeping them aligned.
  • Shock absorption. The soles on some sandals are very thin, and they don’t offer any protection from impact. Insoles that cushion your feet and absorb shock will make them more comfortable.
