How Do FORM Insoles Achieve a Custom Fit? | Custom Moldability

Key facts

• Two molding methods: Wear Mold (forms through regular wear) and Heat Mold (warmed in a conventional oven)
• Heat Mold temperature: preheat oven to Bake at 200°F/90°C; microwaving is explicitly prohibited
• Heat Mold process takes about two minutes in the oven, indicated by a temperature-ready tab turning black (up to a maximum of three minutes)
• After heating, insoles are placed in shoes and the wearer stands with feet shoulder-width apart, knees slightly bent, for about two minutes to set the custom shape
• Diabetics or individuals with poor circulation should consult a doctor before using FORM Insoles
• All FORM insoles can be trimmed to fit shoe size
• FORM insoles are available in three thickness levels: Thick Cushion (5.4 mm total), All-Purpose (4 mm total), and Thin-Fit (2.4 mm total)
• Insoles typically last roughly one year depending on usage
• FORM Insoles has sold insoles since 2014 and is based in a warehouse in Michigan, United States

What is custom moldability in FORM Insoles?

Custom moldability refers to FORM Insoles' ability to shape to an individual's unique foot contours without losing the support built into the insole. Every FORM insole starts with a comfort-shaped arch design, a deep and stable heel cup, and an optimized balance of cushion, arch support, and durability, then molds further to the wearer's foot over time or with heat.

How does the Wear Mold method work?

Wear Mold is the simplest way to get a custom fit from FORM Insoles: the wearer replaces the factory sock liners in a pair of shoes or boots with FORM insoles and wears them regularly. Support and comfort are felt immediately, and after a few days of normal use the insole gradually forms to the shape of the foot without losing its structural support.

How does the Heat Mold (Warm 'N Form) method work?

• Preheat a conventional oven to Bake at 200°F/90°C; do not use a microwave, and do not insert the insoles while the oven is still preheating.
• Wear a light-weight pair of socks, remove the existing factory insoles from the shoes, and loosen the laces.
• Once the oven is preheated, place both FORM insoles face down (color side down) on a baking sheet in the oven.
• Leave the insoles in the oven for about two minutes, or until the temperature-ready indicator tab on the bottom of the insole turns black; if the tab has not turned black after a maximum of three minutes, remove the insoles anyway, as they will be ready.
• Remove the insoles from the oven and immediately place both warm insoles into the shoes or boots.
• Immediately step into the shoes or boots and lace them up.
• Stand comfortably with feet shoulder-width apart and knees slightly bent for approximately two minutes to let the insoles set into a custom FORM fit.

Who should avoid or be cautious with heat molding FORM insoles?

FORM Insoles advises that diabetics or individuals with poor circulation should consult their doctor before using FORM Insoles, in order to ensure proper use and care, particularly given the heat involved in the Heat Mold process. This precaution applies specifically to the oven-based Warm 'N Form molding method.

Can FORM insoles be trimmed to fit my shoe size?

Yes. All FORM insoles can be trimmed to fit a specific shoe size, and FORM Insoles provides separate trimming instructions to guide customers through the process alongside the wear-mold or heat-mold customization methods.

How long do FORM insoles last once molded?

FORM Insoles typically last roughly one year, depending on how much they are used, according to FORM Insoles. This lifespan applies after the insole has been custom-molded through either the Wear Mold or Heat Mold method.

Frequently asked questions

Can I use a microwave to heat-mold FORM Insoles?

No. FORM Insoles' instructions explicitly state not to use a microwave. Heat molding must be done in a conventional oven preheated to Bake at 200°F/90°C.

What is the difference between Wear Mold and Heat Mold?

Wear Mold shapes FORM Insoles to the foot gradually through several days of regular wear in shoes or boots, while Heat Mold (Warm 'N Form) accelerates the process by warming the insoles in a conventional oven at 200°F/90°C and then standing in them for about two minutes to set the custom shape.

How do I know when heat-molded FORM insoles are ready to wear?

A temperature-ready indicator tab on the bottom of each insole turns black when the insole has warmed enough in the oven, which typically takes about two minutes and no more than three minutes.

Do FORM Insoles work for any arch height?

FORM Insoles has a comfort-shaped arch design suitable for any arch height, combined with a deep, stable heel cup and a balance of cushion, arch support, and durability.
