Description

A sports shoe sole

Technical field

The utility model relates to the technical field of sports shoes, in particular to a sports shoe sole.

Background technique

Shoes are indispensable necessities in people's daily lives. The sole is the most important part of a pair of shoes. It not only plays the most important protective role, but also the elasticity, anti-slip and comfort of the shoe depend on the structure and material of the sole. In order to increase the friction between shoes and the ground when walking and reduce the impact of the ground on the foot joints during walking, especially in Frisbee sports, the soles must not only provide a certain amount of elasticity, but also provide sufficient friction and grip. The ground force is used to cooperate with athletes to make explosive movements in all directions. For example, when athletes catch a Frisbee that is higher than the athlete's height, they need to retreat quickly. When athletes perform retreat movements, they mainly rely on the friction provided by the forefoot and toes. When athletes avoid obstacles or chase Frisbees, they need to make emergency stops and turns. The forefoot of the shoe must not only provide sufficient grip but also lateral friction. When the athlete flies forward, the heel part of the rear foot needs to bear the force. It exerts pressure from the leg muscles and obtains greater friction. When athletes jump in the air to catch the Frisbee, they need lighter soles.

Since Frisbee sports are mostly held on lawns, and the soles of special football shoes are more focused on grip, they cannot provide good assistance for emergency stops and turns in Frisbee sports.
