Therm-ic Heat Flat Insole Set + C-Pack 1700B Bluetooth Boot Heaters – Ultra Warm, All-Day Comfort

Rediscover winter adventures with the Therm-ic Heat Flat Insole Set. Designed to transform your existing insoles into a heated, low-profile solution, this kit blends discreet warmth with practical control. The toe-area heating element is ultra-thin, and when covered by the Cambrelle top sheet you’ll barely notice it — until the warmth arrives. The long Cambrelle strips guide the wiring along the boot liner, keeping your feet cozy without bulk. Batteries attach securely to your boots via Velcro, while extension leads let you keep power in your pocket if you prefer.

What’s in the box

• 2 ultra-fine heating elements engineered for steady heat at the toe area
• 2 C-Pack batteries (1700B) for extended warmth
• USB charging lead for convenient recharges
• 2 heating element covers to protect and seal the setup
• Flexible wiring designed to sit outside the liner for a clean fit

The kit is built for simplicity: trim the heated insoles to fit your ski or snowboard boots, then attach the batteries with the included Velcro. The result is a streamlined, low-profile heating system that works with insoles you already own, helping you stay warmer on longer days on the slopes or in cold environments.

Smart heat control at your fingertips

Control your warmth with modern convenience. The insoles pair with Bluetooth and can be managed remotely via the Therm-ic Heat Control App on your phone, or used with the built-in control panel on the battery unit. A single button in the redesigned setup offers three heat settings, delivering steady heat across the day without overloading your feet. The 1700B option extends runtime further, providing up to 17 hours of warmth under the right conditions.

• Bluetooth-enabled control for easy tuning from your smartphone
• Three heat settings accessible from the on-device panel
• Extended runtime with higher-capacity batteries (1700B vs 1300B)

Note that the system is designed to work with Therm-ic-compatible batteries and connectors to ensure proper performance and safety. USB charging adds a layer of convenience for on-the-go recharges, keeping your setup ready for longer sessions.

Designed for real-world use

• Ultra-thin heating elements diffuse heat evenly for a comfortable foot temperature
• Top sheet and wiring layout minimize bulk while preserving boot fit
• Compatibility with most ski and snowboard boots when trimmed to fit
• Extension leads available for keeping batteries out of the pocket if desired

Whether you’re hiking a cold ridge, carving long hours on the mountain, or simply enjoying a winter stroll, this Therm-ic kit offers a practical warmth option that you can tailor to your activity. It’s a thoughtful upgrade for those who want heat where they feel it most, without relying on bulky aftermarket alterations. While warmth is a key benefit, the system’s real value lies in flexibility, control, and the ability to adapt to changing conditions during your day on snow or ice.
