Who Can Benefit from the Sidas F-Essentials Cushioning Gel 3D Insoles?
Designed to support and protect feet, the Cushioning Gel 3D insoles are ideal for anyone who spends a lot of time on their feet. They're ideal for sports that put a lot of strain on the feet and legs, and are also perfect for everyday use, working to protect your feet from strain and stress while also providing stability and control to feet.
Dual Gel Pads for Impact Protection
Two gel pads in each insole provide protection and cushioning to reduce the impacts your feet take in your day-to-day life. A liquid gel pad in the forefoot of the insole keeps your forefoot protected from shocks, and a gel pad at the heel cushions your heel as it strikes the ground while walking or running.
Anatomically Pre-Formed Design
Anatomically pre-formed, the insoles are made with an integrated stabilising shell. This provides support and stability to feet, helping to ensure a more controlled gait for easier and more natural walking.
Anti-Bacterial Top Layer
Fully washable, the top layer of the Sidas Insoles offer substantial microbial resistance, meaning that the insoles actively eliminate bacteria and unpleasant odours as they occur. This not only helps to extend the lifespan of the insoles, but also of the shoe in which they are being worn. Furthermore, the insoles are machine washable on a low heat and gentle setting.

Our Guide to Finding the Perfect Size and Fit
Using Your Shoe Size
For most of our insoles, the easiest way to find the best size for you is to go off of your current shoe size. The majority of our insoles are available in a range of sizes and you can simply select the size that best fits your existing shoes.
Please be aware that, as with shoes, there can be slight variations in the size of insoles. For example a size 8 of one brand might not be exactly the same size and width as the size 8 of another. To help account for these discrepancies, a number of our insoles include dimensions to help you ensure you're getting the right size.
Measuring Your Current Insoles
While using your shoe size to find your best size is a good guide, it is not always foolproof. If you want to guarantee that your insole fit your shoes as closely as possible, we recommend measuring your existing insole and using this as a guide to your size.
To do this, please follow the steps outlined below:
- Remove the existing insole from the shoes you wish to use your new insoles with (please note that not all insoles are removable)
- Measure the insoles at their longest and widest points (see the below diagram for an idea of where this will be
- Match the measurements to the dimensions of the insoles listed, and choose the size that best fits your results
Where Can I Find the Dimensions?
The dimensions for insoles can be found on the "Product Details" tab (please see below) and are usually found in the sizing section of the listing, in a table. Please be aware that not all products currently have the dimensions listed.

What If There Are No Dimensions Listed?
If you do not see the dimensions listed on the Product Details tab, please fill in the form below and we will work to get the relevant information as quickly as possible. We will email you once we have the information that you have requested.
Trimming Your Insoles to Fit
To get the ultimate level of fit from your insoles, you can trim them to make a small adjustment. To trim your insoles, simply follow the steps below:
- Remove your existing insoles from your shoes
- Line up your existing and new insoles at the heel
- Trace the outline of the insoles against the new pair at the toe end (see the image below for an example)
- Carefully cut along the traced line
- Your insoles should now fit your shoes better
Carefully trace the outline of your insole
Please note that not all insoles are suitable for trimming. Most insoles are unsuitable for return once they have been trimmed to fit; we recommend bearing this in mind prior to trimming.
