The Therm-ic Insole Heat Kit + C-Pack 1700B Bundle transforms any insole into a fully heated, app-controlled warmth system for skiing, hiking, or everyday winter wear. Ultra-thin heating elements adhere directly to your existing insoles and connect to the powerful C-Pack 1700B batteries, delivering up to 17 hours of consistent heat. Control warmth manually with three built-in settings or unlock 10 customizable heat levels—plus motion control and eco mode—through the Therm-ic Heat Control Bluetooth® app. Perfect for customizing warmth across multiple boots or shoes, this kit includes everything needed for quick installation, including self-adhesive top covers, cable routing strips, and a USB charging cable. Designed for versatility, comfort, and all-day cold-weather performance, it’s the ideal upgrade for anyone who wants reliable, adjustable heat no matter where winter takes them.

How It Works

Note: Batteries must be attached to the shoe or boot.

2. Cut the insole at the mark to route the cable underneath.

3. Secure the cable using the included adhesive strip.

4. Apply the Cambrelle top cover and trim to your insole shape.

Bluetooth® Pairing Instructions

1. Fully charge both batteries before pairing.

2. Ensure your phone has an internet connection.

3. Install the Therm-ic Heat Control app and open the Connect Your Device page (red + symbol).

4. Hold the power button on both batteries simultaneously — LEDs flash slowly, then turn solid.

5. Release the buttons when LEDs turn solid — they will then flash rapidly (discovery mode).

6. Tap the red + in the app and select Add for each battery.

7. Complete setup to access heat controls.

Pro Tip:
Set the left slider to 10 and the right to 1. The solid-LED battery goes on the left foot; the slow-blinking battery goes on the right.

Important: Pair through the app only — not your phone’s Bluetooth settings.

Battery Storage & Maintenance

• Store in a cool, dry environment (68–77°F / 20–25°C ideal).

• Avoid storing fully charged or fully depleted — keep between 20–80%.

• Charge to ~50% for long-term storage.

• Recharge every 3 months to prevent deep discharge.

• Keep away from heat sources and flammable materials.

• If the battery is fully dead, perform two full charge/discharge cycles to recalibrate.
