To improve blood circulation promoting and fatigue recovering effects by constituting at least the heads of one parts of projections out of a plurality of accupressure projections formed on the surface of a tread mount of magnet products.

A tread mount is formed of synthetic resin in a half-cut cylindrical shape having a semicircular vertical section and being long in the left and right direction. Its central part is swelled into two stages so as to be formed into an elliptical first-stage swell part 2a long in the front/rear direction and a circular second-stage swell part 2b in the center of the swell part 2a. A plurality of projection groups 3 are formed with the two stage swell parts 2a 2b set to the boundary. Small recess and projection parts 4 are formed in the adjacent to the left and right end parts. The projection groups 3 are constituted of synthetic resin projections 5 integrally formed with the tread mount 1, metal projections 6a, 6b having different ionization tendencies from each other, and magnet projections 7. This constitution can provide the blood circulation improvement and fatigue recovery effects as well as acuppressure effect.
