The above embodiment, using the Explicit analytical solver software, Abaqus explore, for kinetic analysis, simulates the movement of spikes through ice material and predicts the force response. The simulation experiment method was to construct four comparison groups, each of which was composed of 2 rows of 10 spikes, the first comparison group being 2 rows of aligned common spikes without spikes, the second comparison group being 2 rows of aligned spikes 1 of this example, the third comparison group being 2 rows of staggered common spikes without spikes, and the fourth comparison group being 2 rows of staggered spikes 1 of this example. The studs of each comparison set are located at the same position above the ice material, the studs are modeled as rigid bodies, and all studs in each comparison set move in synchrony rather than individually. The ice layer was modeled as a deformable solid block with the bottom and side walls of the ice layer constrained, preventing the ice layer from moving and enabling the spikes to penetrate the ice pieces. The simulation experiment process is divided into two steps, namely step one, the spikes of each comparison group are vertically displaced by 4 millimeters in an ice layer; and step two, horizontally displacing the spike by 3.5 millimeters after the spike penetrates through the ice layer. The prediction of the force required to pull the stud horizontally indicates the traction imparted to the stud, and the resistance of each set of configurations is compared to determine which set of configurations will provide the greatest traction. The data measured in the simulation are shown in the following figure, where the horizontal displacement is plotted in mm on the abscissa and the traction force is plotted in N on the ordinate.

The simulation results show that the grip of the shoe spike of the embodiment is obviously better than that of the common shoe spike without nail pricks. And within 3 mm of horizontal displacement, the ground holding power of the staggered arrangement of the spikes is better than that of the aligned arrangement of the spikes.

The sports shoe sole 100 and the sports shoe 1000 with the spikes 1 in the embodiment can be used not only for steel frame snowmobile sports, but also for other sports needing the spikes 1 to grip the ground, such as running spiked shoes. The sports shoes provided with the sports shoe soles have good ground gripping force, improve the stability and acceleration characteristic of sports and improve the competition result.

In other embodiments, the spike comprises a spike body, a spike tip and a spike, wherein the spike tip is located at one end of the spike body, the outer surface of the spike tip is a conical surface, and the spike tip extends from the conical surface of the spike tip in a direction away from the spike body. As the spike tip part is provided with the spike prick, the ground contact area of the spike after being pricked into the racetrack is increased, and higher ground holding force can be provided. Preferably, the spike is a rotation body, the rotation center line of the spike intersects with the rotation center line of the conical surface of the spike tip, so that the spike is easy to pierce the racetrack, and the stress of the spike tip are not easy to form torque force to damage the spike during piercing. Further, the intersection of the rotating center line of the nail spike and the rotating center line of the nail tip conical surface forms an included angle of 30 degrees, and in other embodiments, the intersection of the rotating center line of the nail spike and the rotating center line of the nail tip conical surface forms an included angle smaller than 30 degrees, so that the nail spike can conveniently penetrate into the racetrack and can better provide ground gripping force.

The description of the above specification and examples is intended to be illustrative of the scope of the present application and is not intended to be limiting.
