Each elastic band 140 comprises a length of elastic material 141a-d and a pair of elastic band connection ends 142a-d on each end of the length of elastic material 141a-d. The elastic band connection end 142a-d is sized to fit within the keyhole slots of the hexagon connection hook segments as described above. An inner edge of the elastic band connection ends 142a-d is larger than the straight slots in the hexagon connection hook segments permitting the elastic band connection ends 142a-d to engage the inner surface of the straight slots in the hexagon connection hook segments when coupling the shoe support plate 120 to the frame structure 110, 150. The elastic band connection ends 142a-d are inserted into the keyhole slot in the hexagon connection hook segments and slid inward towards the shoe support plate 120. When the inner surface of the straight slots in the hexagon connection hook segments engages the inner edge of the elastic band connection, the elastic band 140 is forced against the inner end of the straight slot in the hexagon connection hook segments as the elastic band is stretched to engage connection slots 122a-l in the shoe support plate 120. The forces generated by elastic bands 140 on opposite sides of the shoe support plate 120 coupled to opposing sides of the frame structure TOO, 150 creates a retention force that keeps the elastic bands 140 within the straight slots in the hexagon connection hook segments. This same retention force also keeps the elastic bands within the connection slots 122a-l of the shoe support plate 120. The connection slots 122a-l are wide enough to permit the stretchable cords of FIGS. 13a-d to pass long ways through the connection slots.

In a preferred embodiment, the elastic band connection end 175 comprise a cylindrical shaped element 176 having through hole 177 lengthwise through the element 176. The outer circumference of the cylindrical shaped element 176 is sided to be wider than the set of connection hooks 122a-l in the shoe plate 120 and the set of connection hooks in the support frames 110, 150. The stretchable cords 141a-d are coupled to an inner surface of the through hole 177 as the stretchable cords 141a-d are arranged to run out of and away from the cylindrical shaped element 176. A cylindrical shaped element 176 is coupled to each end of the stretchable cords 141a-d to permit the stretchable cords 141a-d to be coupled between the shoe plate 120 and the frame structure 110, 150.
The stretchable cords 141a-d are secured within the through hole 177 in each of the cylindrical shaped element 176 by a pin (not shown) inserted into a hole 178 through the side of the cylindrical shaped element 176 and connecting to the stretchable cords 141a-d. The cylindrical shaped element 176 also includes a set of mounting holes 179a-c to connect a pair of bushings to the top 152a and bottom 152b of the cylindrical shaped element 176.
