How to Trim Superfeet Insoles

A Step-by-Step Guide on How to Trim Superfeet Insoles

Superfeet insoles are renowned for their high-quality and ergonomic design, providing excellent support and comfort for your feet. However, these insoles often come in a universal size, and you might need to trim them to fit your specific shoe size and shape perfectly. Trimming Superfeet insoles is a simple process, but it requires attention to detail to ensure you get the most out of your investment. In this step-by-step guide, we’ll walk you through the process of trimming Superfeet insoles for a customized fit.

Step 1: Gather the Necessary Tools

Before you begin, make sure you have all the tools required for this task:

  1. Superfeet Insoles: Ensure you have the correct model and size of Superfeet insoles that you want to trim.
  2. Marker or Pen: You’ll need a pen or marker to mark the areas you’ll be trimming.
  3. Scissors or a Razor Blade: Use a pair of sharp scissors or a razor blade to cut the insoles. A utility knife can also work, but exercise caution while using it.
  4. Your Shoes: Have the shoes you intend to use the insoles in readily available. This way, you can easily check the fit as you trim the insoles.

Step 2: Identify the Size

Determine the appropriate size of your Superfeet insoles by comparing them to your shoes. Place the insoles inside your shoes and check if they fit well. If the insoles are significantly larger than your shoes, it’s time to trim them to the correct size.

Step 3: Remove the Original Insoles (Optional)

Before you trim your Superfeet insoles, you may want to remove the original insoles from your shoes if they are removable. This step is optional, as some people prefer to place the Superfeet insoles on top of the existing ones. However, if you choose to do so, ensure the combined height doesn’t cause discomfort or make your shoes too tight.

Step 4: Trace the Outline

Take out the Superfeet insoles from your shoes and lay them on a flat surface with the arch side facing down. Place your shoe’s existing insole on top of the Superfeet insole to use it as a guide. Gently trace around the edges of the original insole with a pen or marker onto the Superfeet insole. This will serve as your cutting guide.

Step 5: Begin Trimming

Now, it’s time to trim the Superfeet insoles following the outline you marked. Start cutting along the traced lines carefully. Take your time and make small, precise cuts to avoid overcutting. Remember that it’s better to trim conservatively initially and then make further adjustments if needed.

Step 6: Test the Fit

After the initial trimming, place the Superfeet insoles back into your shoes and test the fit. Pay attention to how they feel as you walk around. Check for any uncomfortable edges or areas that might need further trimming. It’s crucial to ensure the insoles fit snugly inside your shoes without causing any discomfort.

Step 7: Make Further Adjustments (If Needed)

If you feel any areas that are still too big or uncomfortable, remove the insoles from your shoes again and trim those specific areas further. You can always go through Steps 5 and 6 multiple times until you achieve the perfect fit.

Step 8: Smooth the Edges

Once you’re satisfied with the fit, use a fine-grit sandpaper or a nail file to smooth the edges of the trimmed Superfeet insoles. This will prevent any rough or jagged edges that might cause irritation to your feet.

Step 9: Reinstall the Insoles

Finally, place the trimmed Superfeet insoles back into your shoes. Ensure they are properly aligned and centered for maximum support and comfort.


Trimming Superfeet insoles is a straightforward process that allows you to customize the fit to your specific shoe size and shape. By following this step-by-step guide, you can ensure your Superfeet insoles provide optimal support and comfort, helping you stay on your feet comfortably for longer periods. Remember to take your time and make precise cuts, as a well-trimmed insole can make a significant difference in the overall comfort of your shoes. Enjoy your custom-fit Superfeet insoles and the improved support they provide
