Because the player typically leaves the forefoot and rear of the foot as he steps forward, the bottom contour of midsole 10 is shaped like a boat, i.e., both the front and rear ends are designed to warp upward to better accommodate the curvature of the forefoot. When the front sole is pedaled to the ground, the first slope 521 is contacted with the ground, so that the slope of the first slope 521 is smaller and the slope length is longer, which is helpful for enhancing the contact area between the second nail 52 and the ground and increasing the grabbing force. Meanwhile, the structure of the first slope 521 makes the vertical section of the second pin 52 be trapezoid, that is, the contact area between the second pin 52 and the outsole 20 is larger than the contact area with the ground, and the structure has the function of shock absorption and buffering. In other embodiments, the second pin 52 may not have the first slope 521.

Further alternatively, the front end surface of the first nail 51 in the long axis direction is provided with a first slope 521, when the front sole is kicked on the ground, the first slope 521 is contacted with the ground, so that the slope of the first slope 521 is smaller and the slope length is longer, which is helpful for enhancing the contact area between the first nail 51 and the ground and increasing the grabbing force.

In other embodiments, the first nail 51 may not be provided with the first slope 521.

Optionally, a second slope 522 is provided on the rear end surface of the second pin 52 located at the rear side of the second hole 62, and the slope of the first slope 521 is equal to the slope of the second slope 522. When the sole is stepped on, the second nail 52 at the rear side of the second hole 62 leaves the ground, so that the first slope 521 is not contacted with the ground, and the structure of the first slope 521 and the second slope 522 makes the vertical section shape of the second nail 52 be trapezoid, that is, the contact area of the second nail 52 and the outsole 20 is larger than the contact area with the ground, and the structure has the function of shock absorption and buffering. In other embodiments, the second pin 52 located at the rear side of the second hole 62 may be provided without the first slope 521 and the second slope 522.

Further alternatively, the rear end surface of the first pin 51 located at the rear side of the second hole 62 is provided with a second slope 522, and the slope of the first slope 521 is equal to the slope of the second slope 522 thereof. When the front sole is stepped on the ground, the first nail 51 at the rear side of the second hole site 62 leaves the ground, so that the first slope 521 does not contact with the ground, and the structure of the first slope 521 and the second slope 522 makes the vertical section shape of the first nail 51 be trapezoid, that is, the contact area of the first nail 51 and the outsole 20 is larger than the contact area with the ground, and the structure has the function of shock absorption and buffering. In other embodiments, the first nail 51 located at the rear side of the second hole 62 may be provided with no first slope 521 and no second slope 522.

Alternatively, the weight-reducing holes 60 located at the sole portion 40 include third holes 63 disposed opposite to each other and distributed in the left-right direction, and the plurality of cleats 50 are disposed in the circumferential direction of the third holes 63. That is, the fifth pin body 55 is disposed at a space between the two third hole sites 63, and the sixth pin body 56 is disposed in other regions of the half sole portion 40, that is, the weight of the half sole portion 40 is reduced while the fifth pin body 55 sufficiently supports the inner side of the half sole portion 30. In other embodiments, only one third hole 63 may be provided and disposed near the front end of the half sole 40.

Further alternatively, the fifth pin 55 and the sixth pin 56 are each provided with a first slope 521 at the rear end face thereof in the longitudinal direction. In general, the running action is that the rear sole falls to the ground first, and when the rear sole falls to the ground first, the warp part at the rear end of the sole is contacted with the ground first, that is, the first slope body is contacted with the ground first, so that the anti-skid function is achieved. The structure of the first slope 521 makes the vertical cross-section of the second pin 52 be trapezoid, that is, the contact area between the second pin 52 and the outsole 20 is larger than the contact area with the ground, and the structure has the function of damping and buffering, so that the damage of running to the knee and the crotch bone can be effectively slowed down.
