Disclosed are a shock absorption and ventilation enhanced shoe sole and a preparation method therefor. The shoe sole comprises a body. At least one layer of communication-type air passage is provided in the body, and a plurality of first air holes provided in the circumferential side face of the body and a plurality of second air holes provided in the upper surface of the body cooperate, so that air intake and deflation for heat exhaust can be alternately achieved in the process of alternately lifting a foot and treading of a user, thereby preventing heat from accumulating on the foot sole, being beneficial to foot health, reducing foot perspiration, and helping slow down heart rate acceleration; and in addition, the shoe sole can achieve the functions of shock absorption, buffering, ventilation and power assistance, so that the shoe sole is more comfortable to wear.

A plate is used for a sole forming a part of a shoe. The plate includes a front support portion and a center support portion. The front support portion is formed in a flat shape or a curved shape with a single downward protrusion in a cross section in a foot width direction, when the sole is placed on a flat plane. The center support portion has a shape with an upward protrusion and a downward protrusion arranged alternately in the foot width direction in a cross section in the foot width direction, when the sole is placed on the flat plane, where the upward protrusion has a shape curved to protrude upward and the downward protrusion has a shape curved to protrude downward.

A protective device, in particular a safety toe cap, for use with an article of footwear is provided. A safety toe cap of the present technology includes one or more strain hardened portions configured to strengthen or reinforce sections of the safety toe cap against impact, particularly from above. The one or more strain hardened portions have increased strength in relation to adjacent non-strain hardened portions and therefore may maintain adequate protection of a user's toes and foot, while simultaneously allowing for lowered material use and a device with a lightweight, streamlined profile.

Devices with internal flexibility sipes, such as slits, provide improved flexibility, improved cushioning to absorb shock and/or shear forces, and improved stability of support. Siped devices can be used in any existing product that provides or utilizes cushioning and stability. These products include human and other footwear, both soles and uppers, as well as orthotics; athletic, occupational and medical equipment and apparel; padding or cushioning, such as for equipment or tool handles, as well as furniture; balls; tires; and any other structural or support elements in a mechanical, architectural, or any other product.

An article of footwear with a ball contacting surface is disclosed. The ball contacting surface includes a raised peak member at the top and gripping members along a medial side. The ball contacting surface enhances the ability of a wearer to kick a ball with a low trajectory and to control the ball.

A footwear systems utilizing silica derived gel sheets used as a footwear component in upper linings of the footwear. The upper linings provide a cushioning and shock absorption system, particularly in inclined high-heel shoes where the toes and MTP (metatarsophalangeal) joints typically bear most of the weight in such shoes and come in contact with the footwear linings. The material advantageously not only provides padding, but also absorbs shock to further reduce force placed on the foot by dissipating energy of each footstep. In addition like material may be disposed in the sole of the shoe under the ball of the foot to provide shock absorption and cushioning below as well.

A foot and ankle support system using one or more pressure-flexed support bars made of resilient material, each of which can be adjustably positioned and removably attached to selected positions along the medial, lateral, or posterior heel sides of an article of footwear. One end of the support bar is affixed to the base portion of the article of footwear and the other end is affixed to the collar or ankle portion causing the resilient support bar to flex into a bow-like position. Each support bar stores energy and returns resistance when engaged by various directional movements of the foot during walking, running, sports activities or rehabilitation. A plurality of pressure-flexed support bars work in tandem to provide additional support and control of foot inversion and eversion, pronation and supination. An alternative embodiment uses a pressure-flexed bladder type support bar filled with air, gas, liquid gel or other material.
