Cycling Insoles Explained: Do You Really Need Insoles for Cycling Shoes?

As a podiatrist, one of the things I often notice with cyclists is how much attention is paid to the bike setup itself — cleats, pedals, saddle position and bike fit — while the support inside the cycling shoe is often overlooked.

Cycling shoes are quite different from regular footwear. They are typically snug fitting, stiff through the sole and designed to create a stable connection between the foot and the pedal. Because of this, the type of insole inside the shoe can sometimes make a noticeable difference to overall comfort during riding.

Why Are Cycling Shoes Different?

Unlike walking or running shoes, cycling shoes are generally designed with a much firmer sole and a closer fit around the foot. This helps create a more stable feel during pedalling, but it also means there is usually less cushioning less internal space and less flexibility inside the shoe itself.

During longer rides or indoor training sessions, some cyclists begin to notice:

forefoot pressure foot fatigue burning sensations under the ball of the foot or general discomfort inside the shoe.

Sometimes this simply comes down to the amount of pressure being repeatedly placed through the forefoot during cycling.

What Are Cycling Insoles?

Cycling insoles are designed specifically for the shape and fit of cycling footwear. Compared to standard everyday insoles, they are usually:

lower profile lightweight supportive without being overly bulky and shaped to fit snug-fitting cycling shoes.

The aim is generally to improve overall underfoot comfort and foot positioning inside the shoe without taking up too much space.

Are Cycling Insoles Rigid?

This is something many cyclists are unsure about.

Some cycling insoles on the market are very rigid or highly corrective, however many cycling-specific insoles are designed to provide support while still maintaining a degree of flexibility and comfort.

For example, Formthotics Cycling Insoles use firm-density Formax foam, which provides a supportive base while still retaining some flexibility and mouldability. They are noticeably more supportive than a very soft cushioned insole, but they are not a hard plastic orthotic.

This balance is important because cycling shoes already have a very stiff outer sole. In many cases, the goal is not to make the shoe harder — it is simply to create a more stable and comfortable feel underfoot.

Why Some Cyclists Prefer Supportive Insoles

Cycling involves repetitive movement over long periods of time. Even small amounts of foot movement inside the shoe can become noticeable during:

longer rides climbing sessions indoor cycling or high training volumes.

A supportive cycling insole may help:

improve overall underfoot comfort create a more balanced feel inside the shoe reduce unwanted movement inside the cycling shoe and provide a more stable platform during pedalling.

Because cycling shoes are usually very low volume, many cyclists also prefer a low-profile insole that does not make the shoe feel tighter.

Formthotics Cycling Insoles

One cycling-specific option we stock is the Formthotics Cycling Insole.

These insoles are designed specifically for cycling footwear and feature:

firm-density Formax foam a streamlined low-profile shape lightweight construction and a supportive but slightly flexible feel.

They are designed to fit neatly inside cycling shoes without adding unnecessary bulk, making them suitable for:

road cycling shoes indoor cycling shoes recreational cycling footwear and some MTB shoes.

Can Cycling Insoles Help With Comfort?

For many cyclists, yes.

While cycling insoles are not a magic fix for every foot problem, improving the support and fit inside the shoe can sometimes make longer rides feel noticeably more comfortable.

In clinic, I often find cyclists are surprised how much difference small changes inside the shoe can make — particularly when riding regularly or spending long periods clipped into stiff cycling footwear.

Final Thoughts From a Podiatrist

Cycling shoes are built very differently from regular footwear, so it makes sense that the insoles used inside them are also different.

The best cycling insoles are usually not the softest or the most rigid — they are the ones that provide the right balance of:

support low-profile fit stability and comfort inside the shoe.

If you are spending long hours riding or simply looking to improve overall comfort inside your cycling shoes, a cycling-specific insole may be worth considering.
