Warmth where you actually feel the cold
Control without bending down
Change the heat from your pocket instead of taking your boot off in the snow.
Rechargeable
No disposable batteries and nothing to run out halfway through the day.
Trim to fit
Cut to your size along the marked guide for a proper fit in any boot.
Even heat spread
Warmth across the sole rather than one hot spot under the arch.
Before you head out
Two minutes to set up
The insoles slip easily into most boots and everyday shoes, and they can be trimmed for a better fit if needed. Two size ranges cover most adult shoe sizes, from EU 35 to 46. Charge them fully before first use, then start on the lowest heat setting and check your feet regularly until you find the level that suits you.
Out in it
Adjust without stopping
A wireless remote lets you switch the heat on and off and change temperature levels without taking your shoes off. That makes it easy to stay comfortable as conditions change on a freezing commute, a hike, a ski day or a long shift outdoors. If you have reduced sensation in your feet, diabetes or circulation problems, check with your doctor before using them.
Overnight
Charge and go again
The rechargeable batteries provide hours of warmth on a single charge and top up easily between uses, so there are no disposable heat packs to buy. Wipe the insoles clean and let them air dry fully before charging, and never submerge them. Keep them dry and do not use them while sleeping, so they are ready for the next cold morning.
