If you have cold feet all the time, we recommend the 5mm soles. These produce quite a bit more heat than the 3mm sole. However, it is important that you have enough space in the shoes despite the 5mm soles so that you can compress the soles and relieve them again. Because the heat is produced by the permanent compression and relaxation of the material.

In principle, the sole can be used many times. We assume that the heat-producing base material can be compressed to "flame" on the order of about 1 - 1.5 million times. Assuming you take about ¾ meters per step, this results in a range of 2 x 1,000 km. Depending on the condition of the shoe and the socks, however, the upper material will wear off over time. Please note that a sole is quite "maltreated" by the feet and the shoes and therefore wear and tear also occurs from this side over time.
With intensive use, we have already noticed that the upper or lower material comes loose. With a simple iron or an ironing press (without steam and with a cloth between the material and the iron), the material can be partially "ironed on" again.

The chili-feet soles adapt to the shoes by taking and maintaining the shape of the shoe bed. The sole does not bulge, but lies optimally in the shoe. Since the sole does not have a fixed curvature, it is suitable for any type of shoe. The sole also adapts accordingly after changing to a new/different pair of shoes. The soles from chili-feet are therefore suitable for every shoe and foot shape.

The chili-feet are not ideal for alpine skiing. Our extensive tests have shown that you tend to move too little when it comes to alpine skiing. The insulation effect also gained with the sole is there, but the heat production is only very low. The heat production only occurs when you run and thus constantly press on the soles and relieve them again. This is less the case with alpine skiing. The effect is therefore only limited and, from our point of view, not noticeable enough. This is different when snowshoeing, cross-country skiing or walking. This is where chili-feet works best.

Since the sole converts the pressure of body weight into heat, a certain minimum weight is required. The benefit of the thermal insole is limited to the insulating effect with a weight under 48kg. With a lighter weight, the heat production is significantly lower. Whether a noticeable heat is produced at e.g. 35kg has not yet been tested.

This cannot be judged conclusively, since the feeling of heat is always a subjective feeling. However, since the pressure point when cycling is primarily in the front of the ball of the foot, it is quite conceivable that a warming effect occurs. The toes, on the other hand, are the most exposed area and hardly any pressure is exerted when biking and therefore hardly any heat is produced. In this case, it is particularly recommended to use the 5mm sole, as it produces a lot more energy than the 3mm thermal sole.

chili-feet can be purchased directly from this website in our web shop. Also can here all other points of sale can be found.

For logistical reasons, we do not accept orders by email/contact form. Please order via our web shop. If you do not wish to pay by credit card, you can also order with advance payment. For larger order quantities (from 6 products) you are welcome to contact us by email, contact form or telephone.

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

The chili-feet can be cut with normal scissors. The cutting has no negative impact on the functionality of the thermal insole.

Each pack always includes a pair of soles, i.e. for the left and right shoe.

If your order is successful, you will receive a confirmation email with an invoice. The payment instructions can be found on the invoice. You will also 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 Wafe Technology GmbH.

Yes, that is possible. You can carry out the purchase process as normal, even without a customer login.
