If you constantly have cold feet, we recommend the 5mm insoles. These produce significantly more warmth than the 3mm insole. However, it is important that you still have enough space in the shoes despite the 5mm insoles, so that you can compress the insoles and then release them again. Because the heat production occurs through the continuous compressing and relaxing of the material.

The sole can basically be used many times. We assume that the heat-producing base material can be compressed about 1 to 1.5 million times before "fatigue" occurs. Assuming you take about ¾ meter per step, this corresponds to roughly 2 x 1,000 km. However, depending on the condition of the shoe and socks, the upper material will wear down over time. Please note that a sole is quite "battered" by the feet and shoes and therefore will show wear from this side over time.
With intensive use, we have also found that the upper or lining material can come loose. Using a simple iron or a heat press (without steam and with a cloth between the material and the iron), the material can sometimes be "ironed" back into place.

The chili-feet® insoles adapt to the shoes by taking on and maintaining the shape of the shoe bed. The sole does not arch, but rather lies optimally in the shoe. Since the sole has no fixed arch, it is suitable for every type of shoe. The sole also readjusts accordingly after switching to a new/different pair of shoes. The insoles from chili-feet® are therefore suitable for every shoe and foot shape.

The chili-feet® are not optimally suited for alpine skiing. Our extensive tests have shown that during alpine skiing, you move too little over time. Although the insulation effect gained from the sole is present, the heat production is very low. Heat production only occurs when you walk and thus continuously press on the soles and then relieve them again. This is less the case in alpine skiing. Therefore, the effect is limited and, in our view, not sufficiently noticeable. It is different with snowshoeing, cross-country skiing, or walking. There, chili-feet® works best.

Since the soles convert the pressure of body weight into heat, a certain minimum weight is required. The benefit of the heated sole is limited to the insulating effect at a weight under 48kg. At lighter weights, the heat production is significantly lower. Whether noticeable heat is produced at, for example, 35kg has not been tested so far.

This cannot be conclusively assessed, as the sensation of warmth is always a subjective feeling. However, since the pressure point when cycling is primarily at the front of the ball of the foot, it is quite conceivable that a warming effect occurs. On the toes, as the most exposed area, hardly any pressure is applied while biking, and thus hardly any heat is produced. In this case, it is especially recommended to use the 5mm sole, as it produces considerably more energy than the 3mm warming sole.

chili-feet® can be purchased directly on this website in our webshop. Additionally, here all other points of sale can be found.

For logistical reasons, we do not accept orders by email/contact form. Please order through our webshop. There you can also order with prepayment if you do not wish to pay by credit card. For larger order quantities (from 6 products), you are welcome to contact us by email, contact form, or phone.

If you want to place orders on a larger scale, please contact us by email, contact form, or phone.

The chili-feet® can be cut with normal scissors. Cutting does not negatively affect the functionality of the heated insole.

Each package always includes one pair of insoles, that is, for the left and right shoe.

Upon successful order, you will receive a confirmation email with an invoice. The payment instructions are visible on the invoice. Additionally, you can find the same payment instructions on the homepage in the imprint. No payment slip will be sent. Please note that the payment must be made in favor of the company Wafe Technology GmbH.

Yes, that is possible. You can complete the purchase process normally even without customer login.
