FORM insole molding instructions: Mold them at home in a few minutes.
All you need is your oven, a baking sheet, light socks and the shoes you'll wear them in. The base layer softens, you stand in it, and it keeps the shape of your foot.
How heat molding works
-
Step 01200°F
Preheat the oven to 200°F (90°C) and wait until it's fully heated. Put on lightweight socks, take the factory insoles out of your shoes and loosen the laces. Never use a microwave.
-
Step 022 min
Place both insoles face down (color side down) on a baking sheet for two minutes, or until the temperature indicator sticker on the bottom turns black.
-
Step 03Slide
Take them out and immediately put them in your shoes. Step in right away and lace up.
-
Step 042 min
Stand with your feet shoulder-width apart and knees slightly bent for about 2 minutes. That's your custom FORM fit.
Detailed heat-molding instructions (step by step)
Our unique Custom Moldability feature means personalized comfort and support that's just right for you. What sets our insoles apart is their ability to custom-form to your unique foot shape without compromising the essential support where you need it most.
There are two ways to get a FORM custom fit: wear mold them (just wear them, and after a few days of regular use they form to the shape of your feet) or heat mold them in your oven for a custom fit in minutes. Need a shorter insole? See our trimming instructions, or shop insoles now.
Important health information: diabetics or people with poor circulation should consult their doctor before using FORM Insoles to ensure proper use and care.

Step 1
Preheat the oven (don't use a microwave)
Set a regular or conventional oven to bake at 200°F (90°C). Wait until it reaches temperature. Don't put the insoles in while the oven is preheating.
-
Step 2
Wear lightweight socks
Make sure you're wearing a lightweight pair of socks.
-
Step 3
Prepare your shoes
Remove the existing factory insoles from your shoes and loosen any laces.
-
Step 4
Warm the insoles for 2 minutes
Once the oven is preheated, place both FORM insoles face down (color side down) on a baking sheet and leave them in for two minutes, or until the "temperature ready" indicator sticker on the bottom of the insole turns black. If it hasn't turned black after a maximum of 2 minutes, take them out: they're ready.
-
Step 5
Put them straight into your shoes
Remove the insoles from the oven and immediately place both warm insoles into your shoes or boots.
-
Step 6
Step in and lace up
Immediately step into your shoes or boots and lace them up.
-
Step 7
Stand for about 2 minutes
Stand comfortably with your feet shoulder-width apart and knees slightly bent for approximately 2 minutes. Your insoles now have their custom FORM fit.
See it done
Two minutes in the oven, two minutes standing. Here's the whole process.
Prefer to skip the oven?
Wear molding gets you to the same place. Pull the factory liner, drop FORM in and go. After a few days of regular use, body heat and your own weight shape the insoles to your feet, without losing support.
Good to know
Never microwave them
A microwave heats unevenly and will damage the base layer. Oven only.
You can re-mold
Up to 5 times. Moving them to a different pair of shoes? Run the same steps again.
Washable after molding
Machine wash cold, air dry, never in the dryer. The shape holds.
Every pair is covered
Our 100-day fit guarantee covers all of our insoles.
Important health information
Diabetics or people with poor circulation should consult their doctor before using FORM Insoles to ensure proper use and care.
