Heated Insoles

A:  Your heated insoles regulate to a temperature of 111 degrees F on High and 100 degrees F on Medium.  The surface of the insole will reach this temperature when enclosed in footware as it was designed to do.  Exposing the insole to the open air, as if on a table, will cause the insole to become cooler on the surface than intended.

A.  If your feet are not staying warm when you are using your Heated Insoles, but they are producing heat, there are some suggestions we have.  For optimal performance of the Insoles:

  1. Make sure your shoes or boots are completely dry inside.
  2. Insoles should be turned at the first sign of a chill.  It is better to be proactive rather than reactive with this product.
  3. Make sure there is some space/air between the tops of your feet and the top of your boot.  The air between will act as insulation.  If the top of your foot is pressed against the top of your boots, cold from the outside will transfer quickly into your foot.

A: Heated Insoles create an optimal warm environment inside your boot, they don’t get “hot” to the touch.  They will never get as hot as your disposable “Toasty Toes” or similar products.  The reason: Heated Insoles are meant to keep your feet comfortable and warm in cold weather.  They maintain a temperature inside your boot of 100° or  111° (depending on the temperature setting chosen).  Any warmer, and your feet would sweat, and they would put you in an even worse situation.
 
Also, Heated Insoles are thermostatically controlled.  So, if the insoles are in a warm environment, they will most likely not get warm to the touch.  They activate when needed.  For example, think of your house.  If your Thermostat is set to 70° and the temperature in your home reaches 70°, your heat will shut off until needed again.

A: Yes, the Heated Insoles boot and shoe warmers will compress as you wear them. They will contour to your feet.

A: Heated Insoles work in most types of shoes or boots. They fit best in shoes or boots that have removable insoles.

A: No. But to ensure a perfect fit with Heated Insoles, you can remove the existing insoles if needed. Also consider the thickness of the socks you’ll be wearing.

A: If you suffer from any medical foot conditions, consult your physician before using Heated Insoles boot and shoe warmers.

A: Heated Insoles are water resistant, not waterproof. The warranty does not cover Heated Insoles being submerged in water.  They may function properly after being dried out, but there is no guarantee.

A: If Heated Insoles become wet, air-dry them completely before charging them or wearing them again. Do not place the product on a radiator or any other hot surface, because they contain lithium-ion polymer batteries.

A: Cutting beyond the solid line can damage the heating elements and the product, depending on where and how far beyond the line the cut is made. The product may still work; however, the Heated Insoles bonding may be weakened, causing premature failure.

A: Yes. The switch at the heel of each Heated Insole should be turned to the on position before putting them into footwear.

A: Heated Insoles will still work even though the black plastic cap is not closed. The cap is for moisture and dust protection. You should avoid getting foot powder in the area of the charging receptacles.

A: The LED at the heel of each heated insole will flash, either in groups of 2 or 3 lights, depending on the heat setting selected. This means the Heated Insoles are in the heating mode. You should feel the warmth on the upper and lower surfaces of a heated insole when it is held to your hand or cheek.

A: To maintain a comfortable heat level while using Heated Insoles, first make sure they are properly installed. Temperature comfort will also depend on the type, fit, and dryness of the socks and footwear you wear. You can use the no heat setting on the Heated Insoles for a period of time until more heat is needed.

A: When doing strenuous work, power walking, snowshoeing, or cross-country skiing, Heated Insoles should be in no heat mode. At high exertion levels, the body generates enough heat to keep feet warm.

A: Check to make sure the LEDs on the Heated Insoles are flashing in groups of 3 (indicating they are on the high setting) or in groups of 2 (indicating they are on the medium setting). If the LEDs are not flashing, fully discharge the Heated Insoles and then recharge them.  If this still does not fix the problem, please "re-key" or "re-pair" your ThermaCELL Heated Insoles with the remote control using the instructions on the Product Help Page.

A: You can turn off Heated Insoles at any time.

A: There are two ways to turn off Heated Insoles:

  • If the Heated Insoles are not going to be used again immediately, remove them from your footwear and turn the switch on the heel of each heated insole to the off position.
  • If the Heated Insoles are going to be used again immediately, switch the remote control to the no heat setting.

A: Make sure the Heated Insoles have a charge remaining. To do that, check to see if the LEDs on the heel of each heated insole are flashing. If they are not flashing, fully recharge the Heated Insoles.

A: Clean Heated Insoles only with a damp cloth.

A: No. But to ensure a perfect fit with Heated Insoles, you can remove the existing insoles if needed. Also consider the thickness of the socks you’ll be wearing.

Charging and Batteries

A:  Please be sure to only insert the Heated Insoles charger into the charging port on the heel of your ThermaCELL Heated Insoles.  Make sure not to insert the charger into the gaps to the left or right of the charging port, this could damage your Heated Insoles and cause them to malfunction.

A:  For long-term storage of ThermaCELL Heated Insoles, please charge the insole batteries fully before storing them.  They should be stored in a cool, dry place.  It is suggested to recharge the insoles every few months to maintain peak charge.

A: It will take up to 4 hours to charge your ThermaCELL Heated Insoles.

A.  No, leaving your ThermaCELL Heated Insoles plugged in (charging) for a long period of time will not damage the insoles. 

A.  You should push the charging jack into the charging port on the back of the Insole until it "clicks" into place. 

A: Depending on the outside temperature and the insulating quality of the shoes or boots, fully charged Heated Insoles will run about 5 hours on medium setting and about 3.5 hours on high setting.

A: Yes.

A: No. But it is recommended that the switch be in the off position during charging.

A: Heated Insoles can be recharged over 500 times.

A: No. Batteries in the Heated Insoles cannot be replaced.

A: If the Heated Insoles are not getting hot at all, follow these steps:

Drain the batteries of both Heated Insoles completely. To do this, turn the Heated Insoles on using the on/off switch at the heel of the Heated Insoles. Use the remote control to turn the Heated Insoles to the high setting. Let them run until the LED lights on the Heated Insoles turn off. Then recharge them.

If the Heated Insoles are not heating correctly, follow these steps:

Ensure that the Heated Insoles are charged completely. Disconnect the charger. Turn the Heated Insoles to on using the switch on the back of each heel. The LED light on each Heated Insole will flash once every few seconds. On the remote control, press the high button. Now the LED light on each heated insole will flash in groups of 3. Place the Heated Insoles in the refrigerator for 5 to 10 minutes. Take the Heated Insoles out of the refrigerator. Check the LED lights on both Heated Insoles. The lights should be flashing in groups of 3. If the lights of both Heated Insoles are flashing in groups of 3, then the Heated Insoles are in heating mode. Hold them to your hand or cheek and you should feel warmth on the upper and lower sides of each of the Heated Insoles.

Remote Control

A: First, check the remote to ensure the plastic tab has been removed. Then, press any button on the remote control and look to see if the LED on the remote control flashes. If the LED does not flash, put a fresh battery in the remote control. Also check to make sure the Heated Insoles are charged and that the switch at the heel of each heated insole is set to the on position. If none of the above steps solves the problem, call customer service at 1-866-753-3837.

A: The battery should last up to two years with normal usage. But to ensure uninterrupted service from the remote control, replace the battery annually.

A: Make sure the switches on both Heated Insoles are turned to the on position and are fully charged. If the Heated Insoles are not charged, follow the charging directions in the ThermaCELL Heated Insoles Instructions and try activating the Heated Insoles again. If the LEDs on the insoles still do not flash, please try to re-key your remote to the insoles (instructions can be viewed here) or call customer service at 1-866-753-3837.

A: Yes, if the remote control is set to the no heat setting, you will feel no heat. But if the remote control is set to the medium or high setting, and you feel no heat, check to see if the LEDs on the Heated Insoles are flashing in groups of 2 (for the medium setting) or 3 (for the high setting). After 5 minutes, if you still feel no heat, call customer service at 1-866-753-3837.

A: The no heat setting means that no heat is being generated by the Heated Insoles. It is a standby setting indicating that the remote control is active and waiting for a command.

A: The remote control is under warranty for defects for one year from the date of purchase. Contact customer service at 1-866-753-3837 for assistance.

Car Charger

A: Ensure that the car key is turned to the on or accessory position so that power flows to the receptacle. If you are sure that power is available, but the LED on the Heated Insoles Car Charger still does not light, call customer service at 1-866-753-3837.

A: You can charge one heated insole at a time.

A: Check to make sure the plugs on the car charger are fitted securely into the power jacks of each Heated Insole. Also check to make sure the charger receptacle is receiving power and the green LED on the car charger is illuminated.

A: Check to make sure the Heated Insoles Car Charger is receiving power. Check to ensure the plugs on the car charger are fitted securely into the power jacks of each Heated Insole. If the charger is receiving power and all connections are secure, but the Heated Insoles still are not charged, contact customer service at 1-866-753-3837.

A: This indicates that the Heated Insoles are not charging correctly. Check to make sure the plugs on the Heated Insoles Car Charger are fitted securely into the power jacks of each Heated Insole. Also check to make sure the charger receptacle is receiving power and that the green light on the car charger is illuminated. If the LED lights still do not blink properly, contact customer service at 1-866-753-3837.

Global Charger

A: Continuously glowing green is not how the LED on the global charger indicates a full charge. See the answer to the previous question.

A: Ensure that the jacks on the charger are fully plugged into the back of each heated insole. If the LED on the global charger is still not red, call customer service at 1-866-753-3837.

A: Yes. As the batteries reach about 80% charge, the LED light on the charger will begin to flicker between red and green. This is normal.

You can also check the charge status of the Heated Insoles by looking at the LED on the heel of each heated insole. The LEDs will be a constant red when the Heated Insoles are fully charged.

After the charging process is complete, the global charger continues to provide a low-current maintenance charge and the lights continue to flicker. This keeps the batteries at an optimal charge level. The global charger remains in this mode until the charger is disconnected from the Heated Insoles.

A: If the charger is receiving power, the green light should be on. Make sure the electrical outlet is working, or try a different outlet. If the charger still does not have a green light when it is plugged in, call customer service at 1-866-753-3837.

A: No. Do not use other charging devices to charge the Heated Insoles.
