In addition, the first component 21A1 of the first impact response part 21A and the second component 21B1 of the second impact response part 21B are interchangeable. That is to say, the first component 21A1 or the second component 21B1 can be used as the first component 21A1. The impact response part 21A or the second impact response part 21B can meet the user's needs.

The frame 22 has a third response parameter. The frame 22 is made of one of polyethylene and ethylene-vinyl acetate copolymer, but is not limited thereto.

Therefore, the first response parameter of the first impact response part 21A is the stiffness and the second response parameter of the second impact response part 21B is the stiffness respectively depends on the first component 21A1 and the second component 21B1 being made of different materials. The stiffness corresponds to the first response parameter and the second response parameter. The second response parameter of the second impact response part 21B is the stiffness and the third response parameter of the third impact response part 22A is the stiffness respectively depends on the second component 21B1 and The frames 22 are made of the same material and have the same stiffness to correspond to the second response parameter and the third response parameter.

The present invention takes as one embodiment that the first response parameter of the first component 21A1 of the first impact response part 21A is greater than the second response parameter of the second component 21B1 of the second impact response part 21B. Or As the second embodiment, the first response parameter of the first component 21A1 of the first impact response part 21A is smaller than the second response parameter of the second component 21B1 of the second impact response part 21B.
