The present invention relates to functional indoor shoes formed of a functional material having proper thickness, weight and elasticity, heat-keeping and waterproof properties, water-vapor permeability, and durability. A bio-ceramic covered layer is disposed on inside and outside surfaces of the bottom piece forming the appearance, which are formed of a resin covered with a functional material having various colors or shapes so that warming, antibiotic, odor removal and electromagnetic wave shielding functions are performed using far-red light radiation and negative ion emission. The indoor shoes are sewed in consideration of the material property to correspond to the three-dimensional foot shape, health and design functions, and a simple appearance in the form of outer socks without having an ankle piece. |
