STALKMASTER THERMSOLE™
HEATED HUNTING INSOLES
When you stop moving, the heat keeps going. Hours on stand at first light, and your feet go numb long before the deer show up. STALKMASTER THERMSOLE™ puts heat right inside your hunting boots: a 3000 mAh battery in each heel, up to 16 hours at 40 °C, and control from the heel button or your phone, left and right separately.
Sizing tip: S fits EU 35–40 (US men 4–7 / women 5–9), L fits EU 40–46 (US men 7–12). Trim the toe along the printed guides for a perfect fit, never the heel. Between sizes? Go L and trim.

Actually hunt with them. If they don't keep your feet warm on a cold sit, tell us. Most guarantees quietly assume you will never really use the product. This one assumes you will.
Slide it in. Lace up. Stay warm.
THERMSOLE™ heated insoles fit inside your hunting boots and lie flat along the footbed, so all you notice is the heat.

Your STALKMASTER THERMSOLE™ Heated Hunting Insoles (1, 2 or 3 pairs), each pair with its 2-in-1 USB charging cable.
The USB power adapter is not included: any standard 5V/2A adapter works. Boots, clothing and other gear shown in images are not included.
Thicker socks only slow down how fast your feet lose heat, and they squeeze your boots: less circulation, colder toes. Once you sit still, your feet cool down anyway.
The THERMSOLE™ adds heat under your feet, where you lose it to the frozen ground, and lets you dial it up or down for each foot. Switch on before you get cold and stay in the stand until the end of shooting light.
- 3 heat settings: 40 °C / 104 °F, 50 °C / 122 °F, 60 °C / 140 °F (heel button); 30–70 °C in the app
- Battery: 3000 mAh in each insole, sealed in a resin-reinforced heel
- Runtime: up to 16 h at 40 °C, about 7 h at 50 °C (manufacturer figures)
- Charging: USB 5V/2A, 2–3 hours, 2-in-1 cable included
- App: iOS & Android, left/right control, timer 15–120 min, °C/°F
- Water resistance: IPX7 (manufacturer rating)
- Sizes: S (EU 35–40, 23.5–26.5 cm) and L (EU 40–46, 27–30 cm), trim-to-fit
- Heel thickness: 18.6 mm
Wipe or gently rinse the surface with a damp cloth and mild soap. Do not wring, twist hard or soak for long. Let the insoles dry completely before switching them on. Charge only with a 5V/2A adapter.
Yes, a 90-day field-tested guarantee. Actually hunt in it. If it doesn't hold up or the size isn't right, contact us and we'll exchange it. Field use does not void the guarantee.
WARM FEET. STAY FOCUSED.
When you stop moving, the heat keeps going.
On a long sit, the cold comes up from the frozen ground. Your feet are the first thing to go, and once they are numb, every minute in the stand feels like ten.
The THERMSOLE™ fixes it:
1. Heat right under your feet, inside your own boots.
2. Three settings from the heel button, 30–70 °C from the app.
3. Up to 16 hours on one charge at 40 °C.
From the blind to the woods, adjust the heat to the morning and keep your mind on what is in front of you.
Warm feet. Stay focused.
