As the name implies, core means the core of the sun. The light of the sun that illuminates all living things, including us humans, and the world. The center (nucleus) of the sun is the driving force that constantly produces that light (energy). For us humans, it is both feet that generate that energy when we are active. We thought that the feet (shoes) that support both feet and are the driving force of energy are the core of human beings. The people who get it feel the certain amount of heat we generate. People who wear it can share the feeling of constant light shining in their daily lives. People who walk can work forever and forever. We are aiming for such manufacturing. It is usually written as Solar Core, but to make it more familiar and familiar to the ears, replace the core "c" with the temperature symbol "℃" as sun instead of solar, and use it. With the amount of heat, we chose "sun ℃ ore".
