The Therm-ic Smartpack 950 was discontinued by Therm-ic in 2018 and is no longer available.
Please see our current selection of battery boot heaters.
The Therm-ic SmartPack 950
is unique because it uses Lithium-ion batteries which are lighter in weight than AA or nickel metal hydride batteries. Lithium-ion batteries weigh almost half of what the other system batteries weigh and are smaller in size so they take up less room on your boots.
Therm-ic SmartPack 950 with TrimFit heat system features;
- The TrimFit heating elements fit every type of winter boots that have removable insoles. The heating element installs easily on any current insole, custom insole or orthodics. You can install it yourself. It takes about 60 minutes to do the installation in both boots.
- The batteries give you up to 18 hours of comfortable heat when freshly charged and can be charged up to 1000 times.
Our comments; The Therm-ic SmartPack 950 with the TrimFit system is the least expensive lithium-ion battery system that us and Therm-ic offers. It may not have a global charger but the charger has overcharge protection which is important to have.
