Attached to be removed. The sole 5 of the training shoe 1 according to the present invention has the front side (toe) of the sole higher than the rear side (heel) of the sole, and has a minimum thickness at the rear end of the heel part of the sole. 5mm
As described above, the heel contact surface 53 that is inclined about 10 ° (= θ1) downward with respect to the line L1 connecting the tip 51 of the toe of the shoe sole and the rear end 52 of the heel is formed. The toe contact surface 54 of the sole of the shoe is about 23 ° upward with respect to the extension line L2 of the heel contact surface 53 with the tread portion corresponding to the ball of the foot on the sole as a base point K.
(= Θ2) It is inclined and formed into a curved shape substantially parallel to the sole of the foot.

[0010] A plurality of projections and depressions are provided on the contact surface side of the sole 5 to prevent slippage. Heel contact surface 5
The ground surface of the ground surface 3 may have a flat shape, but may have a shape in which the center of the ground surface is slightly depressed in an arc shape to make the sole more cushioned.

The training shoe 1 of the present invention has a last 6.
The toe tip 51 and the heel rear end 52 of the upper surface of the shoe sole 5 correspond to the tip of the toe portion and the heel rear end of the bottom surface 61 of the last 6 and the shoe with the insole 4 attached. Upper surface of sole 5 is last 6
Corresponds to the bottom surface 61 of FIG.

The sole 5 is made of a synthetic rubber such as natural rubber, styrene-butadiene rubber, butadiene rubber, urethane rubber, or a synthetic resin such as vinyl chloride, or a material obtained by mixing these. As described above, it is formed into a weight that can load a leg. Therefore, in the training shoe 1 of the present invention, since the front part of the sole is formed thicker, a shoe weighing about two to three times that of a normal shoe can be obtained, and the center of gravity of the shoe is located forward of the center of the shoe. Is set to be located at
