Cold feet can cut even the most perfect ski day short. After all, just like your fingers, your feet and toes are particularly sensitive to temperature variations, as they receive less stimulation. Just think about it: When it’s cold, your feet can reach temperatures of 28 °C – which is a far cry from the 37 °C core temperature your body needs.
That’s why many winter sports enthusiasts who are prone to cold feet opt for a simple solution: heated insoles. These handy gadgets can not only prevent pain and cramping, they are also your secret weapon to extending your time on the mountain.

Remember the 28 °C we talked about earlier? Your feet can easily get this cold – be it during skiing or because of a medical condition. For instance, Reynaud’s disease, a chronic circulation problem, can cause loss of feeling, tingling, cold feet or cold hands.
To maintain the core temperature as far as possible and fight the cold, your body’s temperature regulation system will stimulate blood flow. When you start to feel cold, this will send pain signals to your brain. As a result, more than 90 per cent of available energy will be used to warm up the affected muscles. The result: shivering, reduced muscle power and decreased endurance.
In fact, without heated insoles like those by Therm-ic, as much as 75 per cent of muscle power and endurance is lost!
Heated insoles like the Heat Flat or the Heat 3D by Therm-ic, instantly deliver the required heat to critical areas. Muscle power is restored, blood flow is stimulated, and your shivering will cease. This will not only benefit your well-being and endurance – full physical and muscular strength also means reduced risk of injury!
Heated insoles by Therm-ic feature ultra-fine heating elements that diffuse constant heat and quickly lead to an optimal foot temperature. This way, you’ll be back at full strength in no time at all!
