## Title
Footwear with integral massager

## Abstract

An integral massaging means within heel and sole portions within footwear is herein disclosed. The footwear resembles a conventional pair of shoes or sandals with a soft upper area and cushioned soles; however, the sole area is slightly thicker than normal to accommodate a battery pack and a series of vibrating motors across the sole, thereby producing a massaging effect. The duration and intensity of the vibrating motors may be controlled using external control switches and may be activated by pressing an ON/OFF button or by using a remote controller. The massaging apparatus may be activated whether a wearer is sitting down, lying down, or standing upright. User replaceable batteries are provided and accessed through a door located on the bottom of the footwear.

## Background
RELATED APPLICATIONS
The present invention was first described in and claims the benefit of U.S. Provisional Application No. 61/066,989 filed on Feb. 26, 2008, the entire disclosures of which are incorporated herein by reference.


FIELD OF THE INVENTION
The present invention relates generally to footwear and, more particularly, to said footwear comprising an integral, remote-controlled, battery-operated massaging apparatus.
BACKGROUND OF THE INVENTION
Footwear comprises garments worn on the feet for adornment and protection and have been around for thousands of years. In fact the oldest known footwear made of woven sagebrush bark indicates humans have been wearing shoes for ten-thousand (10,000) years. Over the generations footwear has become highly technical and specialized for various activities, including running, hiking, everyday wear, and the like. Boots, sandals, loafers, and slippers made from leather, plastic, rubber, and even wood can be found in shoe stores around the world. Although footwear protects a user's foot and improvements in comfort have increased, regularly wearing shoes can cause feet to become fatigued, uncomfortable, and even damaged over a period of time.
Many people find relaxation and overall comfort from receiving a personal massage. While these massages can be applied virtually anywhere on the human body, one area in particular that is often massaged is the foot. For many people, direct and firm massage to the sole of the foot can reduce muscle aches and pains and even reduce stress and strain. If nothing else, it just feels good. While many people massage their feet immediately after removing their shoes, it is usually only for a limited time and thus the beneficial results are short-lived. While larger automatic massaging devices do exist, most are not specifically designed for the foot and cannot easily be used while at work, while simply waiting for the bus, or while performing any other activity.
Accordingly, there exists a need for a means by which one's feet can protected in a normal manner while always having a means to receive a soothing and relaxing foot massage, still while not encumbering the user from performing other activities. The development of the invention herein described fulfills this need.
Various attempts have been made in the past to overcome these problems and provide for messaging footwear. Among the solutions are several U.S. Pat. No. 4,694,831, issued in the name of Seltzer, describes footwear having an inner sole with an upwardly projecting raised flat foot support and spaced massage bumps which provide a sort of acupressure stimulation to the bottom of a wearer's foot. However, unlike the present apparatus, the Seltzer massage footwear relies heavily on precise location of the acupressure bumps to provide relief and requires the wearer to apply the massaging pressure.
U.S. Pat. No. 5,682,690, issued in the name of Chang, describe footwear having an elongated sole and a plurality of spring-loaded massage rods which provide an opposing pressure point to the bottom of the wearer's foot during walking or other activity. However, unlike the present apparatus, the Chang footwear with adjustable massage units again relies on pressure point locations to provide massaging relief requires the wearer to manually participate in the massage.
U.S. Pat. No. 5,802,743, issued in the name of Chien, describes a massaging slipper having a movable massaging ball mounted to a top surface of the slipper. However, unlike the present apparatus, the Chien structure of massaging slipper does not provide the functionality of everyday footwear.
Other known prior art for footwear with massaging means include U.S. Pat. Nos. 5,287,638 and 6,234,987.
While these devices fulfill their respective, particular objectives and appear to disclose various attempts to provide a means of massaging the foot and providing varying levels of protection; none of the prior art particularly discloses footwear which provide the protection and comfort of everyday shoes and provides for the soothing effects of a foot massage. Accordingly, there exists a need for an apparatus that operates without the disadvantages as described above.
SUMMARY OF THE INVENTION
In view of the foregoing prior art, the inventor recognized a problem and the object of the present apparatus is to solve the aforementioned inherent disadvantages and thus it has been observed that there is need for footwear with integral massager.
To achieve the above objectives, it is an object of the present apparatus to provide footwear having an integral massaging apparatus within a sole portion. The footwear resembles and functions in a substantially similar manner to that of a conventional pair of shoes or sandals comprising a soft upper area and cushioned soles.
A further object of the present apparatus is to provide footwear comprising a sole area which is thicker than conventional shoes in order to accommodate a battery pack and a plurality of vibrating motors dispersed across the sole which provide a soothing massage effect to a bottom portion of a wearer's foot.
Yet still another object of the present apparatus is to provide a plurality of internal vibrating motors which are activated and controlled by a side mounted control switches. The control switches provide a means of turning the massaging effect on and off as well as control the frequency and duration of operation.
Yet still another object of the present apparatus is to provide a time controlling means and an intensity controlling means.
Yet still another object of the present apparatus is to provide an access door which provides the wearer with access to a replaceable power source.
Yet still another object of the present apparatus is to provide a remote control unit which provides a remote means of activating and controlling the massaging effect of the invention via a radio frequency transmitter, receiver and processing unit.
Yet still another object of the present apparatus is provide the wearer with a means of receiving the massaging effect while sitting down, lying down, or standing upright.
Yet still another object of the present apparatus is to provide a method for utilizing footwear with integral massager.
Further objects and advantages of the present apparatus will become apparent from a consideration of the drawings and ensuing description.
