<P>PROBLEM TO BE SOLVED: To improve a blood circulation by irradiating far-infrared rays on a foot. <P>SOLUTION: The foot protective tool has a stain-resistant outside cover 21 whose inside has a thermal insulation action and an antimicrobial action, forms an inner body 23 for irradiating far-infrared rays, also inside of which an inner cover 24 is formed with thin thickness for irradiating far-infrared rays or having the antimicrobial action and forms a foot shape to house a foot of a person. Synergistic far-infrared-ray effects are achieved with effects of the far-infrared rays from the inner body 23 which are not reduced due to interruption or absorption of the far-infrared rays irradiated from the inner body 23 by the inside cover 24. The far-infrared rays from the inner body 23 are irradiated sufficiently even at a lower temperature than that of a human body, and have short wavelength and an instantaneous effect. <P>COPYRIGHT: (C)2003,JPO |
