Insole

a technology of insoles and shoes, applied in the direction of insoles, uppers, bootlegs, etc., can solve the problems of insufficient footwear to hold the insole in position during a normal gait, inability to use insoles with open style footwear, and restricted foot movement of wearers, so as to achieve convenient and economical making and use

Benefits of technology

[0006] It is another object of the present invention to provide an insole that can be worn with open style footwear.
[0008] It is yet another object of the present invention to provide an insole that provides cushioning at the forefoot and heel areas.
[0010] It is a yet further object of the present invention to provide an insole that is easy and economical to make and use.

Problems solved by technology

However, when wearing open style footwear where the perimeter of the footwear is exposed, such as sandals, clogs, slides, slingbacks and the like, the boundary of the footwear is not sufficient to hold the insole in position during a normal gait.
As a result, such insoles cannot be used with open style footwear.
Further, with conventional shoes, the wearer's foot is restricted by the upper which is connected to the outer and / or inner sole.
As a result, any insole placed therein is also limited by the same upper.
However, this is not true with open style footwear in which the wearer's foot is given greater freedom of movement.
As a result, the wearer may notice a step between the relatively thick edge of the insole and the inner sole of the footwear, causing discomfort to the wearer.

first embodiment

[0028] Referring to the drawings in detail, and initially to FIGS. 1-6 thereof, a left insole 10 according to the present invention is adapted to be placed in an article of footwear, as is well known. A right insole (not shown) is identical to left insole 10 and is a mirror image thereof.

[0029] Insole 10 was designed to fit the shape of a human left foot and therefore includes a curved toe or forefoot portion 12, a heel portion 14, and a mid-foot portion 16 which connects forefoot portion 12 and heel portion 14 together.

[0030] Insole 10 is formed by a generally planar cushioning layer 18, having a generally dome shaped, lower pillow 20 extending from the lower surface of cushioning layer 18 at forefoot portion 12 and a generally dome shaped, lower pillow 22 extending from the lower surface of cushioning layer 18 at heel portion 14.

[0031] In one embodiment, layer 18 and pillows 20 and 22 are formed as a unitary, one-piece layer of the same material, which is preferably a polyuretha...

second embodiment

[0043] Referring now to FIGS. 7-9, a left insole 110 according to the present invention will now be described. A right insole (not shown) is identical to left insole 110 and is a mirror image thereof.

[0044] Insole 110 has the same shape as insole 10 of FIGS. 1-6, and therefore includes a curved toe or forefoot portion 112, a heel portion 114, and a mid-foot portion 116 which connects forefoot portion 112 and heel portion 114 together.

[0045] Insole 110 is formed by a generally planar cushioning layer 118, having a generally dome shaped, lower pillow 120 extending from the lower surface of cushioning layer 118 at forefoot portion 112 and a generally dome shaped, lower pillow 122 extending from the lower surface of cushioning layer 118 at heel portion 114.

[0046] In this embodiment, layer 118 and pillows 120 and 122 are formed as a unitary, one-piece layer of a gel material. The gel material can be of the same general type described in U.S. Pat. No. 6,598,321 to the same assignee here...

Abstract

A removable full length insole for insertion into open style footwear, includes a forefoot portion, a heel portion and a mid-foot portion connecting together the forefoot portion and the heel portion; a uniform thickness cushioning layer of a resilient material extending through the forefoot portion, heel portion and mid-foot portion; a substantially dome shaped pillow extending down from the cushioning layer at the forefoot portion and heel portion; and an arrangement for maintaining the insole in position in the footwear during a gait.

Description

BACKGROUND OF THE INVENTION [0001] The present invention relates generally to shoe insoles or inserts, and more particularly, to insoles particularly adapted to be used with open style footwear. [0002] Various types of insoles are known which fit within shoes in order to correct various foot problems, alleviate pain and otherwise provide more comfort to the wearer. Examples of such insoles are those sold by the assignee of the present invention under the trademark Dr. SCHOLL'S®. [0003] However, when wearing open style footwear where the perimeter of the footwear is exposed, such as sandals, clogs, slides, slingbacks and the like, the boundary of the footwear is not sufficient to hold the insole in position during a normal gait. As a result, such insoles cannot be used with open style footwear. [0004] Further, with conventional shoes, the wearer's foot is restricted by the upper which is connected to the outer and / or inner sole. As a result, any insole placed therein is also limited ...
