In the cold of winter, when the chill spreads from your feet to your entire body, every step feels like treading on ice, a chill that penetrates your bones and leaves you feeling gloomy. You may have tried thick, fleece insoles, but while they offer warmth, they also bring the unpleasant prospect of foot odor from sweating. You may have used a heat pack, but you’ve always worried about the safety risks. Those arch fit sole insoles that require constant charging add a chore to your busy life… Now, our self-heating, constant-temperature insoles, developed specifically for winter, bring you warmth and comfort.
Instant Warmth
Simply slip them on, and the insoles instantly heat up to a constant, comfortable 54°C in a fraction of a second. This doesn’t rely on external power or chemicals, but rather on the unique, patented Ousulai smart fabric. Whether you’re indoors or out, warmth is always with you.

The high-elastic material of the Ousulai surface is not only soft and conforms to the foot’s shape, but also offers both thermostatic and breathable properties, ensuring the ideal “warmth without being stuffy.”
This winter, don’t let your feet suffer from cold and discomfort. Choosing this self-heating thermostatic arch fit sole insole is a warm, comfortable, and elegant way to spend the winter. Let it become your most reliable companion for winter travel.
