The Heated Insoles are designed to deliver convenient warmth directly inside your shoes or boots, helping keep your feet more comfortable during colder conditions.
The Heated Insoles with Ankle-Worn Power Pack are designed to provide portable warmth directly inside your shoes or boots, making it easier to stay comfortable in cold weather without being limited to a fixed power source.
The slim heated insoles fit inside compatible footwear and provide gentle warmth underfoot. Each insole connects to its own rechargeable power pack, allowing both feet to receive independent heating.
A dedicated ankle-worn battery pouch allows the power pack to be carried around the upper ankle or lower leg area. The main purpose of this design is convenience and portability, allowing the heating system to continue working while you are walking, commuting or moving outdoors.
There is no need to remain near a wall outlet during use. Once the rechargeable power packs are connected, the insoles can provide mobile heating wherever you go.
Using the system is simple: secure the ankle strap, place the power pack into the pouch, insert the heated insoles into your shoes, and connect the cable.
The portable design makes these heated insoles especially suitable for winter commuting, walking, travel, outdoor work, camping and other cold-weather activities.

Yes. CNT film is die-cut to any 2D profile, and electrodes are routed to your outline — no tooling cost for most shapes.
Wearable builds use detachable controllers and sealed film, allowing hand or machine wash of the fabric assembly.
Dual protection: NTC closed-loop regulation plus an independent hardware cut-off, with an auto shut-off timer.
Full private label: logo, manual, colorbox, barcode and FBA-compliant cartons prepared to your brand guidelines.
Functional samples ship in 7–10 days; sample fees are credited back against your first bulk order.
