Heated Insoles Instructions – How to Keep Feet Warm in Winter
It’s easy to learn how to keep feet warm in winter with ThermaCELL Heated Insoles instructions. See the video or written instructions below or download a PDF.
Learn how to warm feet with ThermaCELL Heated Insoles. Follow these easy directions.
You can trim insoles to fit boots or shoes if needed.
- Be sure to follow the warning statement printed on the bottom of the insoles that indicate where not to cut.
- The two cutting lines are for reference only.
- Do not cut beyond the solid line, or excessively bend the insoles. This will cause damage to the heating elements and the product.
When sizing Heated Insoles, be sure to consider the thickness of the socks you will use with your footwear. Your socks are also an important part of how to keep feet warm in winter.
The lithium-ion polymer batteries embedded in the insoles can be recharged up to 500 times.
The batteries are embedded in the insole material and cannot be accessed.
Follow these steps to charge the batteries:
- Set the on/off switch at the heel of each insole to the off (left) position.
- Plug the Heated Insoles Global Charger into an electrical outlet. The LED light on the charger will glow green.
- Plug the Heated Insoles Global Charger cables into each insole’s recharge port. These are located at the heel of each insole. Once the connections are established, the charger LED light will glow red and the LED on the rear of the insole will blink red, indicating that the charging process is underway.
- Charge the insoles until the LED light on the global charger glows green with brief flashes of red and the LED on the rear of the insole continuously glows red. This indicates that the insoles are fully charged.
- Unplug the global charger and remove the cables from each insole. The ThermaCELL Heated Insoles are now ready for use.
For best performance, occasionally completely drain the batteries of both insoles before recharging. To do this, turn the insoles on using the on/off switch at the heel of the insole. Use the remote control to set the insoles to the high setting. Let the insoles heat on high until the LED lights on the insoles turn off.
- Turn each heated insole on by moving the on/off switch to the heel of the insole to the on (right) position. The red LED light on each insole will flash intermittently and insoles will default to the no heat setting on the remote control. Note: If no heat setting (medium, high) is selected, the insoles do not generate heat and they use minimal battery power.
- Unpack the ThermaCELL Heated Insoles Remote Control. Remove the protective tab. Removing the tab activates the already-installed, replaceable battery.
- Select a setting on the remote by using the buttons high (111 degrees Fahrenheit), medium (100 degrees Fahrenheit), or no heat.
- Insert the insoles into shoes or boots by following the directions printed on the bottom of the insoles. If needed, trim insoles to fit. Insert insoles, fabric side up, into shoes.
- Use the remote control to operate the insoles while shoes or boots are on your feet. The LED light on the remote control will flash once to confirm that a heat setting has been transmitted to the insole.
- The LED lights on the insoles flash to indicate which setting they are on:
• 1 flash every several seconds = no heat setting
• 2 flashes, repeated every several seconds = medium setting
• 3 flashes, repeated every several seconds = high setting
- The remote control can be used up to 7 feet away from the insoles.
- For a perfect fit, you can remove existing insoles from shoes or boots if needed to make space for Heated Insoles.
- Use the tabs at the heel end of Heated Insoles to easily remove the insoles from footwear after use.
- Fully charged insoles will run on medium heat for about 5 hours before needing to be recharged, depending on weather conditions and the quality of the footwear.
- When the wearer is engaged in strenuous work, the body generates enough heat to keep the feet warm. So the insoles should be set to the no heat setting in that situation.
- The type, fit, and dryness of the footwear and socks being worn with Heated Insoles are also important components of how to keep feet warm in winter.
- The best sock to use with Heated Insoles is a medium weight sock that wicks away moisture and keeps feet dry.
- The heating element in each insole extends from the toe area to the ball of the feet. The arch and heel areas are not heated.
There are two ways to turn off ThermaCELL Heated Insoles:
- Remove the insoles from the shoes and turn the on/off switch to off (left). The switch is located at the heel of the insoles. The remote control will automatically turn off when the insoles are switched off.
- Leave the insoles in the shoes and use the no heat setting on the remote control.
- Turn off insoles when not in use.
- Store Heated Insoles and Global Charger in a clean, dry place.
- Use only the ThermaCELL Heated Insoles Global Charger to charge ThermaCELL Heated Insoles.
- Charge the insoles only when they are outside of shoes or boots.
- If the insoles are not used for a prolonged period, charge them completely before using again. Lithium-ion polymer batteries self-discharge ~5% of their power each month.
- Do not damage the heating elements by bending the insoles.
- Cut insoles to size only as indicated in the instructions.
- Clean only with a damp cloth.
- Do not submerge insoles in water. Insoles are water resistant, not waterproof. If insoles become submerged in water, air dry before using or charging.
- To dry insoles, air dry only. Do not place heated insoles on radiators or any other hot surface.
- When charging insoles, the switch must be set to the off (left) position.
- See the FAQ for more helpful information.
The Heated Insoles Remote Control comes equipped with one lithium cell, #CR2032. The battery should last up to 2 years with normal use. But to ensure uninterrupted service from the remote, replace the battery each year.
Follow these steps to replace the battery:
- Remove the 4 small Phillips screws on the underside of the remote control.
- Lay both sides of the remote control open on a table. Remove the green printed circuit board and turn the board over so the battery holder is face up. Using a coin, push the battery out from under the battery holder.
- Insert the new battery into the holder, making certain that the positive (+) side of the battery is face up.
- Return the green circuit board to its original position, making sure the battery is on the underside of the printed circuit board. Put the housing front (with the black rubber spacer piece) over the circuit board.
- With the two sides of the remote control together, secure the two side panels by replacing the 4 small Phillips screws.
The insoles and remote control contain batteries. Batteries must be disposed of in accordance with local laws and regulations.
- Use ThermaCELL Heated Insoles according to instructions.
- Be aware of early sensations of a burn:
- An area of a foot becomes hot
- Any area of a foot feels as if you are standing on a small pebble or pointed object, and may or may not feel hot
- If you feel the early warning signs of a foot burn, immediately discontinue the use of the Heated Insoles.
- If you think you have a burn, see a physician immediately.
ThermaCELL Heated Insoles and the remote that controls them are keyed at the factory so that your remote will operate only your insoles. To pair a replacement remote with your current insoles, follow these steps:
- Turn the switches of both Heated Insoles to the on (right) position.
- Insert the charging cable into the recharge port at the back of one insole, 2 times, very quickly. Make sure the charging cable plug is inserted completely into the insole jack each time. Then do the same thing 2 times with the other insole.
- The LED on each insole will begin flashing. This indicates the insoles are in learning mode.
- While the LED lights on both insoles are flashing, press any button on the remote. The code synchronization will process automatically. The LED light will stop flashing to indicate that the pairing process is complete.
