Photoelectron is a special ceramic that uses far-infrared energy emitted from the human body to warm the body to the core. By combining it with various materials, it can be used to achieve a more effective heat retention effect. It also has the characteristic of improving the evaporation and quick-drying properties of moisture such as sweat. 
Uses "THERMOLITE" which provides warmth and a dry effect with its macaroni-shaped hollow fiber structure, making it comfortable to wear.
Mid-length rounded toe model.
By increasing the number of threads at the toes and heels, the warmth retention and strength are improved.
Support rubber prevents slipping.
Pile lining. *By not using pile above the ankles, slipping down is reduced.
