Technical field

The present invention relates generally to an improved shoe insole, and more particularly to an insole providing improved cushioning and support to the wearer ' s foot.

The insole is inserted into the user's shoe to provide one or more advantages in comfort of the wearer or support of the foot. The insole is generally sold in pairs, one of each pair being configured for use on the user's right footwear, and the other being configured for use on the left footwear. It is advantageous to provide a suitable structure for the insole to meet the user's purpose.

Human feet are a very complex biological mechanism. The load on the foot at the time of heel strike is typically about 1.5 times the weight of a person when he or she is walking. When running or carrying extra weight such as a backpack, the load on the foot may exceed three times the weight. The multiple bones, muscles, ligaments and tendons of the feet function to absorb and dissipate impact forces, support weight and other loads, and provide force for propulsion. Properly designed shoe insole can assist the foot to perform these functions and protect the foot from injury.

An insole may be tailored to address the specific needs of the individual. These insole may be made based on the cast of the end user's foot or may be made of a thermoplastic material molded into the contours of the end user's foot. Like most custom made items, customized insole tends to be expensive due to the small amount and the vast amount of time required to properly manufacture and fit these insole. As such, it is not practical to manufacture such tailored insole for the general public.

To make it practical for distribution to the general public, the insole should be able to provide benefits to the user without the need for personalized adjustments and fittings. A commonly available over-the-counter type 1 insole emphasizes foot cushioning to maximize shock absorption. In normal individuals, the cushioning insole is suitably performed while engaged in mild or moderate activities such as walking or running. That is, buffer insole provides sufficient buffer and support for these activities. However, for more intense or technically challenging behavior, such as carrying a heavy backpack or crossing a rough terrain, a normal cushioning insole would not be appropriate. Under these conditions, the buffer insole itself will not provide sufficient support and control and tends to bottom out during use by compressing the buffer insole to the maximum.

Other types of commercial insole emphasize control. Typically, such insole is manufactured to be relatively stiff and rigid to control foot bending and torsion by restricting foot motion. Rigid structures are good for motion control, but are not very forgiving. As a result, when the motion of the foot reaches the limit imposed by the rigid structure, the load on the foot tends to change abruptly and increases the structural load on the foot. Because biological tissues, such as tendons and ligaments, are sensitive to the speed at which they are loaded, a sudden change in load can cause injury or damage to the foot, ankle or leg.

In view of the above, it would be desirable to provide a commercially available insole that provides both cushioning and control. It would also be desirable to provide both buffering and control and to provide a practical insole for use by the general public during cross-training or triathlon-related activities.

Applicants have received a patent for an insole having a support cushion and a plurality of pods positioned thereon. These patents are described in U.S. Patent Nos. 7,484,319; 7,665,169; 7,908, 768; And 8,250,784. These conventional patents, however, do not address the problem of setting up improved cushioning and stability, possible shifting of the insole during shoe operation, or improved cushioning characteristics to handle running and walking customs.

The forefoot pad 107 may be made from a low density polyurethane memory foam, ethylene glycol polyurethane, ethylene vinyl acetate (EVA), prebonded EVA, polyurethane (PU), or thermoplastic rubber (TPR) (Pattern spacing 1.0 mm to 1.50 mm). The rigidity of the forefoot pad 107 can be adjusted to handle over / under spur, over / under spur problems, and other problems associated with foot motion by changing pad size, shape, and material properties. The configuration, material, and location of the forefoot pad 107 provide cushioning and act in conjunction with other items to stabilize the ankle. The forefoot pad and heel pad are made of rubber or synthetic rubber, including those made of a neoprene synthetic rubber layer which is a polymer.

The outer edge of the forefoot pad (107) connects the base edge to the upper edge of the forefoot pad (107). In use, the forefoot pad indentation region 102A and the forefoot pad 107 lie beneath the "ball" of the foot and the big toe portion of the user's feet, except for the first metatarsal head or inner ball of the user's feet. Forefoot pad 107 provides buffering and energy return at landing from vertical jumping. Which serves as a support for the propulsion pads and the metatarsal head, especially the first and second metatarsals, of the user's feet. The forefoot pad 107 has a diamond-shaped groove pattern 117 on its bottom surface to improve the forefoot cushioning properties, which results in a static friction and adhesion force of the insole along the inner bottom surface of the user's shoe, And improves the durability and cushioning of the forefoot pad compared to known materials.

The support cushion 105 is made of a polyurethane polyester glycol (hardness 10 to 30 ash ± 3 - low density). The support cushion indent region 102B is located in the middle portion and the heel region of the bottom surface of the insole. The mid-leg to heel cushion indentation region 102B extends from an inner edge proximate the inner boundary to an outer edge proximate the outer boundary of the base layer 102 and from a distal edge at a proximal end of the forefoot pad indentation region 102A Extends to a proximal edge proximate to the heel end 104 of the base. The medial side of the distal edge is shaped to receive the downward motion of the first metatarsal during toe retraction. The support cushion 105 is molded substantially identically to the cushion-to-heel support cushion indentation region 102B and has a base-facing surface and a shoe-facing surface. A base-facing surface is secured to the cushion-to-heel cushion indentation region 102B.

The midsole / heel support cushion 105 has an arch 119A raised in the medial arch region and a curved indent 132 located along at least two major angles from the longitudinal axis, It extends from the heel to the toes. The longitudinally curved indentations 132 extend in the first angled direction compared to the longitudinal axis of the insole 100. The first angled orientation is measured relative to the major axis length of the longitudinal curved indent 132. The first angled orientation is approximately 5 degrees to 65 degrees as compared to the longitudinal axis, which is a longitudinal axis extending from the heel to the toe on the insole 100. The longitudinal curved indent 132 in the raised arch region 119A provides additional stiffness to the raised arch support which improves the support of the raised arch 119A in the support cushion 105. [ In this configuration, these indentations 132 also facilitate polyurethane material flow in the region of the midsole, while helping to minimize cavitation caused by air trapping. The curved indent 132 of the arch region also allows the arch region to fold and conform to the shoe thus providing a more receptive design.
