ABSTRACT:
A device and method of use for reducing knee bend, and therefore knee stress, when climbing and descending stairs. The method includes a first step of removably securing to a first foot of a user a device having an elevation of approximately half a step rise. A second method step includes lifting a second foot of the user onto a first stair step while applying full body weight to the first knee. A third method step includes lifting the first foot and the device while applying full body weight to a second knee in order to place the first foot and the device on the first step adjacent to the second foot. Lifting the second foot and lifting the first foot and the device are achieved while the first and second knees are bent no more than an angle necessary to climb approximately half a step rise. The sequential foot lifting is repeated until the user has climbed the stairs. The device includes a foot securing portion for removably attaching it to only one of a user's feet. The device also includes an elevating portion connected to the foot securing portion. Together both portions have an elevation approximately half a step rise.
