“Are these insoles trimmable?”  is a question we get asked frequently at insoles.com.  For most of our insoles the answer is: Yes, they are.  These days most of the over-the-counter insoles are trimmable, which is a great feature.

Choose your insole size according to your foot size.  It will likely be a perfect fit in your shoe.  If not, follow these 4 simple steps to trim the end of the insole.  This insole trimming guide is only for full-length insoles; ¾ length insoles should fit in the shoe without trimming.

STEP 1

Remove the existing liner out of the shoe.  Removing the liner will ensure there is plenty of room for your foot.  (If the manufacturer shoe liner it is not removable then you will need to leave it in the shoe and wear it with the insole.)

STEP 2

Use the liner you have removed from the shoe as a pattern.  Line up the edge of the heel of the liner with edge of the heel on the insole and also the inside edges of both.  Use a pen or marker to trace the outline of the liner onto the insole.  If your shoe does not have a removable liner to use for tracing, you will have to do your best to use the shoe itself as a pattern.  There may be a little guesswork involved for the length.

STEP 3

Trim the insole along the line you have marked.  It is best to trim just outside the line to ensure it will not be too short.  It is better to trim less and need to take more off  later to ensure you do not make the insole too short.

ADDITIONAL TIPS

Make Sure to Get the Correct Insole Size

Even though you can trim just about any size insole to make them fit inside your shoe, it is still important that you get the proper size for your foot.  Sizing on insoles corresponds with your foot and shoe size, but it also corresponds with your arch length.  The insole will be the most effective if you have the right insert for your arch length.  Since you are paying the extra bucks to add the support to your shoe, you want to make sure that the support is in the right place to be most effective for you.

Don’t Trim too Much Off

Making the insole too short will leave a gap at the end of the insole.  You want to avoid this because it can cause your toes to grip in the shoe in an unnatural way.  Trim less rather than more.  You can always trim a little more off the end if it is still to long for the shoe.

Purchase Insoles for Each Pair of Shoes

Although you can move your insoles from shoe to shoe, it really is best to have a pair of insoles for each pair of your shoes.  This allows you to make sure the fit for each shoe is perfect. You can trim each insole so that it fits exactly in your shoe.   It also helps you keep track of when your insoles should be replaced because the general recommendation is to replace your insoles when you replace your shoes.  So when the budget allows, it’s good to go ahead and get a set of insoles for each pair of shoes that you will wear them in.
