Buyers Guide – Insoles for Shoes That Are Too Big


The insole should be thick enough to take up the extra space within your shoe.

If the shoe is too deep for you, your foot should touch the upper when the insole is placed inside the shoe.

Arch Support

The insole should have strong arch support that provides the right amount of support for your arch. Medium to high is usually sufficient. Try to match the arch in your shoe if that’s comfortable and supportive.


A full-length insole is a better choice than a ¾ insole, as it fills more space within your shoe. You can trim it to fit your shoe if it’s slightly too long.

Heel Cup

A deep heel cup should also be a feature on your insole. This will help to keep your foot in the right place, maintain alignment, and prevent them from moving inside the shoe.

Tips to Make Big Shoes Fit Smaller


Insoles can easily be used to take up extra space within the shoe and provide extra support as well.

They’re usually easy to find at a running store or even a drug store. Make sure to get the right support for your foot.

Heel Grips

If your shoe is slightly too long and you find your foot sliding back and forth as you walk, heel grips could be the solution.

They are small, self-adhesive cushions that you stick to the inside back of the heel, right behind your Achilles tendon.

This not only provides extra cushioning for the heel, but it takes up space in the back of the shoe. This means there’s less extra space in the shoe and your foot won’t slide forward anymore as it’s held by the heel grip.

Stack Up Your Socks

Wearing thicker socks or wearing more than one pair of socks will help to fill up extra space in your shoe.

This is an excellent option in winter. However, in summer, your feet may become too warm with extra layers.

Go to the Professionals

If none of these options work for you, you can take your shoes to a professional cobbler. They can insert extra padding such as tongue pads, insole cushioning, or heel grips into the lining of the shoe and conceal it so it looks natural.


What Are the Benefits of Insoles?

As well as filling some of the extra space in your shoe, insoles provide extra cushioning and support for the muscles and tendons of your feet.

They are an excellent option when your shoes aren’t providing as much support as you need, as they’re easy to use and accessible.

Can Insoles Help With Too Big Shoes?

Yes, insoles can help you to fill up some of the extra space if your shoes are too big for your feet.

However, this will only help if the extra space is in the depth of the shoe, not the length of the shoe.
