The disposable warming insole that can be placed inside the shoe is the perfect solution for cold days. The insole provides pleasant and even warmth for up to 9 hours, keeping your feet warm and comfortable all day. The heat-activated reaction of the sole starts simply by opening the package, so its introduction is quick and effortless.
The heat in the insole comes from natural ingredients that react with air. The ingredients list includes iron powder, water, activated carbon, vermiculite and sodium chloride. The combination of these ingredients creates a thermal reaction that maintains comfortable warmth for a long time. Activated carbon and vermiculite help regulate and keep the heat consistent, while iron powder and water initiate a chemical reaction to produce heat.
This warming insole is an excellent choice for outdoor activities in the winter, and it also brings comfort to situations where you move in cooler conditions for longer periods of time.
