About this product
This complete heating system lets you transform any insole into heated insoles. The bundle combines Therm-ic’s Insole Heat Kit with a pair of C-Pack 1300B batteries, providing up to 13 hours of warmth and the flexibility of Bluetooth® app control.
How it works
The ultra-thin heating elements adhere to your insoles and connect directly to the C-Pack batteries. Once installed, you can control the heat manually using the power button or adjust settings remotely using the Therm-ic Heat Control app. Perfect for ski boots, hiking footwear, or everyday shoes. (Note: Batteries must be attached to the shoe or boot.)
Includes:
- 2x Therm-ic C-Pack 1300B batteries
- 2x ultra-thin heating elements
- 2x self-adhesive Cambrelle top covers
- 2x cable routing strips
- 1x USB charging cable (5V/2A wall cube not included)
Heating duration (C-Pack 1300B):
- Level 1: up to 13 hours
- Level 2: up to 7.5 hours
- Level 3: up to 4.5 hours
Key features:
- Three manually adjustable heat levels built into the battery
- Bluetooth® app with 10 customizable levels, motion control, and eco mode
- Same heat output across all settings — Bluetooth adds control, not more power
-
Manual levels map to app levels:
- Manual 1 = App Level 3
- Manual 2 = App Level 6
- Manual 3 = App Level 10
- Ideal for customizing warmth across multiple boots or shoes
- Charging cable included — requires 5V/2A USB wall adapter (not included)
Installation instructions:
- Place the heating element at the front of your insole and mark the black cross point
- Cut the insole at the mark to route the cable underneath
- Secure the cable with the included adhesive strip
- Apply the Cambrelle top cover and trim to fit your insole shape

Bluetooth pairing instructions:
- Fully charge both batteries before pairing
- Ensure your phone has an internet connection
- Install the Therm-ic Heat Control app and go to the “Connect Your Device” page (red “+” symbol)
- Hold the power button on both batteries simultaneously — the LEDs will flash slowly, then turn solid
- Release the buttons when the LEDs turn solid — they will now flash rapidly (discovery mode)
- Tap the red “+” in the app and select “Add” for each battery
- Complete setup to access heat output controls
- Tip: Set the left slider to 10 and the right to 1 — the solid LED battery goes on the left foot, the slow-blinking LED goes on the right
- *All Bluetooth pairing must be done through the app, not your phone’s Bluetooth settings
Battery storage & maintenance tips:
- Store in a cool, dry place — ideally between 68°F and 77°F (20–25°C)
- Avoid full discharge or 100% charge — aim to keep between 20–80% for long-term storage
- Charge to ~50% before storing for extended periods
- Recharge every 3 months to avoid deep discharge and battery damage
- Keep away from flammable materials and direct heat sources
- If the battery is completely dead, charge and discharge it fully twice to recalibrate
Compatible with:
- Ski boots or footwear that allows attachment of the battery pack
- Our current heating elements are compatible only with Therm-ic C-Pack battery systems (not backward compatible with older models)
This bundle comes ready to install. Just add a USB wall adapter (5V/2A) to charge and you’re ready for the cold.
