A kind of hygienical shoes with mobile magnet piece, which can produce the static and dynamic magnet field for the sole of foot of human body, especially it can carry out the magnetotherapy for the sole of foot with take advantage of the static and dynamic magnet field generated respectively at sole when human body stops and walks. Wherein the shoe sole includes a lower sole and a insole covering on the upper surface of the lower sole; the grooves is set on the upper surface of insole, and the mobile magnet pieces is provided on the bottom of groove. When the shoes according to the present invention are wore on foot for walking, as the foot lift up and fall down, the front and back portions of grooves will change their relative position repeatedly, and the magnet pieces in the grooves will move fore-and-aft depending on the obliquity of the bottom of groove under the effect of gravity, which result in the movement of magnet field, i.e. the dynamic magnet field. In resting state, the magnet pieces generate the static magnet field. When human body stops and walks, the shoes according to the present invention perform the magnetotherapy for the sole of foot with two forms of magnetic field thereby improving the effect of magnetotherapy in the sole of foot.
