Definitions
- the present invention relates to a disposable insole pad, and more particularly, a thin disposable insole pad that is removably attachable to a user's foot and placed between the user's foot and a footwear insole.
- Insole or footbed is often disposed a top of the sole of footwear to be in contact with a foot to provide warmth, comfort, or support of the foot's structure (e.g. arch support).
- An insole can be a fixed inner sole or a removable sole. It is usually made of synthetic material, rubber, silicone, plastics, leathers, gels, or fabrics, and thus, it is relatively thick and placed inside of the footwear for relatively extended period of time without washing.
- Insoles are generally not adapted to the problem of sweating or odor caused by the foot. Insoles are typically thick, and even when washable, they are not washed frequently, which exacerbates such problems that often result in bacterial or microbes growth, which leads to sticky, odor-filled, and unhygienic footwear. Furthermore, washing an insole is time consuming and inconvenient. Sometimes, an insole has to be hand washed. Sometimes, insoles are made from non-washable materials, and thus, washing can damage or destroy them. Besides, wearing footwear barefooted or without socks has become a fashion trend and, accordingly, conventional thick insoles are not well suited for such times.
- a thin disposable insole pad which is removably attachable to a user's foot, is provided, as there is a need for a device that accomplishes this goal.

- Yet another object of the invention is to provide a disposable insole pad 100 which includes an absorbent layer 10 , first and second side attachment parts 25 , 26 , and a heel attachment part 27 .
- the first and second side attachment parts 25 , 26 are extended from the absorbent layer 10 toward opposite sides of the absorbent layer 10 for being respectively attached to opposite sides of the user's foot.
- the heel attachment part 27 is extended from the absorbent layer for being attached to a heel of the user's foot.
- the insole pad of the present invention is thin and disposable and can effectively absorb a large amount of liquid or sweat, and thus, it is sanitary and hygienic; (2) the insole pad of the present invention is thin and attachable to the bottom of the foot, and thus, it is well suited for the fashion trends of today where wearing footwear (e.g.
- barefoot or without socks is preferred at least without any outward appearance of socks;
- antibacterial agents, antimicrobials, and/or deodorizers are added to the absorbent layer, and thus, the present invention prevents or reduce bacterial or microbial growth, which removes foul odor inside the footwear;
- the size of the present invention can be adjusted by cutting toe or hill-end of the present invention;
- the present invention is thin and foldable, and thus, not only making it easy to stack and transport but also reducing transportation costs;
- first and second side attachments parts and the heel attachment part can effectively hold the present invention to the user's foot;

Description
- The present invention relates to a disposable insole pad, and more particularly, a thin disposable insole pad that is removably attachable to a user's foot and placed between the user's foot and a footwear insole.
- Insole or footbed is often disposed a top of the sole of footwear to be in contact with a foot to provide warmth, comfort, or support of the foot's structure (e.g. arch support). An insole can be a fixed inner sole or a removable sole. It is usually made of synthetic material, rubber, silicone, plastics, leathers, gels, or fabrics, and thus, it is relatively thick and placed inside of the footwear for relatively extended period of time without washing.
- Insoles are generally not adapted to the problem of sweating or odor caused by the foot. Insoles are typically thick, and even when washable, they are not washed frequently, which exacerbates such problems that often result in bacterial or microbes growth, which leads to sticky, odor-filled, and unhygienic footwear. Furthermore, washing an insole is time consuming and inconvenient. Sometimes, an insole has to be hand washed. Sometimes, insoles are made from non-washable materials, and thus, washing can damage or destroy them. Besides, wearing footwear barefooted or without socks has become a fashion trend and, accordingly, conventional thick insoles are not well suited for such times.
- Therefore, to solve the above problems, a thin disposable insole pad, which is removably attachable to a user's foot, is provided, as there is a need for a device that accomplishes this goal. This invention is directed to solve these problems and satisfy the long-felt need.
- The present invention contrives to solve the disadvantages of the prior art. The present invention provides a disposable insole pad that is removably attachable to a user's foot and placed between the user's foot and a footwear insole.
- The object of the invention is to provide a
disposable insole pad 100 which includes anabsorbent layer 10, aremovable skin adhesive 20, afirst release liner 30, and ananti-slip member 40. Theremovable skin adhesive 20 is attached to thetop surface 12 of theabsorbent layer 10, and theanti-slip member 40 is attached to thebottom surface 14 of theabsorbent layer 10. Theremovable skin adhesive 20 is intended to be removably attached to a user's foot, and afirst release liner 30 is provided to cover theremovable adhesive 20. The user wears thepresent invention 100 by removing thefirst release liner 30 and attaching his foot to theremovable skin adhesive 20, and then, he wears a shoe such that theanti-slip member 40 is to be in contact with a shoe insole. - Another object of the invention is to provide a
disposable insole pad 100 which includes anabsorbent layer 10, ananti-slip member 40, arelease liner 50, and atoe cap 60.
