[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] Example 1

[0019] like Figures 1-4 As shown, this embodiment includes a midsole 100 and an outsole 200. The midsole 100 has a streamlined outer contour, with its forefoot bottom surface forming a first arc surface that curves upward from back to front, and its heel bottom surface forming a second arc surface that curves upward from front to back. The midsole 100 is provided with a groove 104 for placing a cushioning plate 102. The upper surface of the cushioning plate 102 is flush with the upper surface of the midsole 100. Below the groove 104, there is a hollow area 106 that penetrates the lower surface of the midsole 100. The outsole 200 is attached to the bottom of the midsole 100 and is provided with a plurality of hollow portions 202 that penetrate its upper and lower surfaces.

[0020] In this embodiment, the midsole 100 has a first arc surface and a second arc surface at the front and back, which can simulate the walking trajectory of the foot, reduce the resistance when the toes leave the ground, accelerate the transmission of the impact force to the midfoot, reduce the heel dwell time, and ensure a smooth transition from heel to forefoot during running.
