The frame is divided into two parts, consisting of a left frame and a right frame. Multiple sets of grooves are provided on the opposite surfaces of the upper sole 1 and the lower sole 2. Each set of grooves consists of two grooves. The grooves of the upper sole 1 and the lower sole 2 are all connected, and the upper and lower grooves are combined to form an arc-shaped connecting channel 7. A hemispherical connecting part 8 is formed at the middle of each set of grooves of the upper sole 1 and the lower sole 2. The connecting parts 8 are fitted together. A connecting plate 12 is installed on the left frame and the right frame opposite the connecting channel 7. The connecting plates 12 are inserted into the connecting channel 7 and abut against each other. The outer side of the connecting part 8 is wrapped by the connecting plate 12.
[0023] In this embodiment, the left frame is composed of multiple first arc-shaped plates 4 and first rubber plates 13. The first rubber plates 13 are all installed between the first arc-shaped plates 4, and the left frame formed by the combination of the first rubber plates 13 and the first arc-shaped plates 4 matches the outer contour of the left half of the upper sole 1 and the lower sole 2. The right frame is composed of multiple second arc-shaped plates 3 and second rubber plates 6. The second rubber plates 6 are all installed between the second arc-shaped plates 3, and the right frame formed by the combination of the second rubber plates 6 and the second arc-shaped plates 3 matches the outer contour of the right half of the upper sole 1 and the lower sole 2 to ensure the sealing between the upper sole and the lower sole after installation.
