The Basic Powerpack with Perform insoles• Can be used world wide with AA battery power!
• Quick and easy installation! Thermicsoles already have the heating elements built in. All you need to do is remove your current insoles, trim to size, install in boots, plug in and turn on. Fits all types of winter boots.
• Impulse Control- The warmth is transferred from the battery pack to the heating elements by impulses which deliver more energy than a constant power on used with other brands.
• Comfortable warmth up to 12 hours with fresh alkaline AA batteries (not included).
This can be your best choice because it's the easiest system to install and AA batteries can be used world wide. This is also the least expensive option for those who only need heat occasionally.
Therm-ic Basic with Perform insoles features
Select between 3 settings to determine the amount of heat you need
• Setting #1: 37C/99F and lasts approximately 12 hours.
• Setting #2: 42C/108F and lasts approximately 5.5 hours.
• Setting #3: 70C/158F and lasts approximately 2 hours.
Results are based on fresh AA Alkaline batteries. Expect about 10-20% less results when you use rechargeable or disposable batteries. Keep in mind, you don't have the heat on all the time, only when you need it. For instance, you turn the power off when you go inside for lunch or if you are not cold.
• Instructions on how to use.
• 2 battery housings that hold 4- AA batteries each and clip on the back of a boot.
• Battery specs- weight with 4 batteries- 5.3 ounces, size- 3" high x 2 3/4" wide x 1" deep.
• 2 Thermicsoles which are anatomic 3D shaped insoles with connecting wires. The Perform insoles give great support for stability and balance. They are made of high quality EVA foam. The heating elements are built into the toe area of the insole so all you need to do is remove your current insoles, trim the Thermicsoles to the same size and slide the Thermicsoles in. You can opt to run the wire for the battery right up the back or put a small slit in your boot liners and run the wire between the liner and shell. (We recommend the later.) It takes less than 30 minutes to install.
• Therm-ic offers a 1 year manufactures warranty against any defects.
