Double-layer shockproof sole

Abstract

The invention provides a double-layer shockproof sole, which comprises an outsole and a midsole. The double-layer shockproof sole is characterized in that double-layer elastic shockproof pads are arranged on the midsole and at least distributed in the front and the rear of the midsole, the upper elastic shockproof pad is provided with a first upward protrusion, the lower elastic shockproof pad is provided with a second downward protrusion, and the first upward hollow protrusion and the second downward hollow protrusion are arranged oppositely so that an inner cavity of the first protrusion is opposite to an inner cavity of the second protrusion. The double-layer shockproof sole has excellent shock proofing effect, thinner positions of the sole such as the front and the like are capable of structural shock proofing, movement impact and fatigue can be relieved effectively, sport injury is avoided, movement stability of the sole is unaffected, movement starting force can be increased, walking or sports are easier, and vitality is multiplied.

Description

technical field [0001] The invention belongs to the field of shoemaking, in particular to a shock-absorbing shoe sole. Background technique [0002] The shoe is mainly composed of the upper and the sole. Whether the shoe is comfortable or not depends first on the sole. The sole is the part of the shoe that is in direct contact with the ground. It is directly subject to the friction and impact of the ground, and at the same time transmits the reaction force of the ground to the foot. The sole includes the insole, midsole and outsole from top to bottom. For sports shoes, the sole needs to have sufficient shock absorption function in order to avoid the injury caused by the impact of sports, so as to achieve the purpose of exercising or competing. People hope that the feet can be effectively protected during sports, and at the same time reduce Exercise fatigue. [0003] At present, the realization of the cushioning and shock-absorbing function of sports shoes mainly relies on ...

AI Technical Summary

Problems solved by technology

For example, the shock absorption design of common soles is a fully enclosed shock-absorbing airbag based on aerodynamic principles. However, once the seal of the shock-absorbing airbag is damaged and the air leaks, the shock-absorbing effect will be lost, and the shock-absorbing airbag is thick and soft. When the sole transmits the ground impact force to the sole of the foot, the shock-absorbing airbag is easy to be skewed and cannot be corrected, and the sole cannot be restored to its original shape to protect the foot from being sprained; there are also EVA high-elastic materials used to make the midsole, and its shock-absorbing effect only depends on The midsole itself has elasticity and acts as a shock absorber. Its shock absorber effect is not great, and it does not have anti-twist function.

The general shock-absorbing structure uses shock-absorbing columns, etc., which have a single function and only have a shock-absorbing function, and the shock-absorbing columns can basically only be used on the heel, because a higher heel can accommodate a longer vertical At the same time, the use of shock-absorbing columns also reduces the torsion resistance of the soles, and the movement stability is poor.
