Freezing legs in winter is a common problem that causes unpleasant sensations, discomfort and health problems. People are looking for a solution to the problem of cold and wet feet, as well as the dangers that hide from it. This project solves the problem in an extremely flexible way, based entirely on an innovative idea. I was involved in the development of the product, of Innovatronic Ltd., with the owner Todor Nestorov. In relation to development and implementation of innovation – OP “Innovation and Competitiveness”. The project is supported by years of experience and analysis. It was necessary to develop two basic principles for warming the feet.
