To provide footwear with a magnet for allowing more electrons to act on blood by intercepting the escape of electrons.

A permanent magnet is mounted to the footwear. The permanent magnet is mounted such that magnetic flux formed of the N-pole and S-pole rises toward the internal direction of the foot on the footwear from the surface of the footwear, and nonmagnetic conductive metal members are arranged in the positions facing the magnetic flux, with their faces intersecting a direction almost orthogonal to the magnetic flux direction. When wearing the footwear, blood inside the foot thereby passes through the inside of the magnetic flux. The electric field generated in an orthogonal direction to the direction of the magnetic flux and bloodstream is thereby intercepted by the nonmagnetic conductive metal members to prevent the leakage of electrons, thus allowing the electrons to act on the blood.
