Epicstar Warm shoe insoles, size. L, 30 sets

Epicstar warming shoe insoles in size L (41–46) keep your feet warm for up to 8 hours. With a thickness of just 2mm, they fit into any type of footwear. They are activated by contact with the air and start to warm up as soon as they are removed from the packaging.

Simple activation and use

The warming insoles work on the principle of an exothermic reaction, which starts when the packaging is opened and they come into contact with oxygen. A mixture of iron powder and activated carbon immediately begins to generate heat, reaching a temperature of 39 to 40°C. To interrupt the heating, simply take the insoles out, which stops the reaction. When you take them out again, the process reactivates until the total eight-hour heating time is used up.

Slim profile in any shoe

With a thickness of just 2mm, these insoles are designed not to take up space in your shoe or restrict your movement. You can put them in all types of footwear without any worries. Their slim profile ensures they adapt well. This makes them suitable for all-day wear.

Natural composition

The composition of the insoles is based on natural and non-toxic materials. They contain a mixture of iron powder, activated carbon, water, salt and earth. You don't have to worry about any harmful chemicals. Once the warming effect is completely used up, you can safely dispose of the insoles in regular household waste, as they do not harm the environment.
