Benefits of technology

[0005] The primary object of the present invention is to provide a shoe sole that provides an energy return force to reduce pressures to the forefoot area, and requires less effort to walk during toe off stance.
[0006] Another object of the present invention is to provide a shoe sole that includes two support members to support the plantar arch of the foot. This will provide stability to both the medial and lateral columns of the rearfoot.

Problems solved by technology

The load of the body could hurt the ankle joint and / or other parts of the foot.
The conventional shoe soles are not satisfied because they lack to provide sufficient support to the foot.

Embodiment Construction

[0014] Referring to FIGS. 1 to 4, the shoe sole of the present invention is arranged on a top of the outsole 1 of a shoe and comprises a sole body 10 which is made by a flexible and soft material and a flexible heel member 13 is connected to a heel portion of the sole body 10. The heel member 13 includes a concavity which has a proper curvature for matching the wearer's heel and a rear end of the heel member 13 extends upward from an inside of the concavity about 10 to 15 degrees.

[0015] Two solid and stiff support members 12 are connected to two sides of an arch area of the sole body 10 wherein the arch area is located corresponding to a plantar arch of wearer's foot. The two support members 12 each have an L-shaped cross section including a horizontal portion and a vertical portion. The horizontal portion is attached to a bottom of the sole body 10 and the vertical portion is attached to a side of the sole body 10

Abstract

A shoe sole includes a sole body and a flexible heel member is connected to a bottom of a heel portion of the sole body and two support members are connected to two sides of an arch area of the sole body to support the wearer's plantar arch. A composite material plate is connected to the bottom of the sole body and extends toward the heel portion. The plate has two thinner ends and a thick middle portion.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a shoe sole that includes two side support members at two sides of the plantar arch, a flexible heel member at the heel and a composite material plate connected to the front end and extending toward the heel. The plate is transferring energy from the heel onto the forefoot to reduce the pressure on the wearer's foot, and requires less effort to walk during toe off stance. BACKGROUND OF THE INVENTION [0002] A conventional way of walking or jogging is to put the heel on the ground first and the sole, the ball of the foot, the transverse arch and the toes touches the ground in sequence. The load of the body could hurt the ankle joint and / or other parts of the foot. Although there are different types of shoe soles are developed to absorb the load applied to the joints of the wearer's foot, most of the shoe soles are simply made by soft material such as foam which can be deformed to reduce the pressure that applies to the joi...
