DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to Fig. 1, the shoe of the present invention comprises a first part which includes a sole 11 and two fastening units 12 are connected to the front end and the rear end thereof. Each of the fastening units 12 includes a buckle 121 for fastening the wearer's foot to the first part 1.
A second part 2 includes a C-shaped resilient plate 21 and a top of the resilient plate 21 is fixed to an underside of the first part 1. The resilient plate 21 can be made by glass fibers, carbon fibers, plastic or metal strip. A first connection unit 212 is connected to a front end of the resilient plate 21 and a second connection unit 211 connected to a rear end of the resilient plate 21. The first connection unit 212 includes two clamping plates 2123 between which the first end of the resilient plate 21 is securely connected. A first tubular portion 2121 is connected to the two clamp plates 2123 and a first pin 2122 extends through the first tubular portion 2121. The second connection unit 211 includes two clamping plates 2113 between which the second end of the resilient plate 21 is securely connected. A second tubular portion 2111 is connected to the two clamp plates 2113 and a second pin 2122 extends through the second tubular portion 2111.
A base 22 includes two lugs 2221 extending from the top of the front end 222 of the base 22 and each lug 2221 includes a hole 2222 defined therethrough.
Two bushes 2223 are engaged with the two holes 2222 and each bush 2223 includes a through hole 2224. The first pin 2122 pivotably extends through the two through holes 2224 of the two bushes 2223 in the two lugs 2221. Two lugs 2211 extend from the top of a rear end 221 of the base 22 and each lug 2211 has an elongate slot 2212 defined therethrough. Two bushes 2213 are engaged with the two elongate slots 2212 and each bush 2213 includes an elongate slot 2214. The second pin 2112 movably extends through the two elongate slots 2214 of the two bushes 2213 in the two lugs 2211. An outsole 223 is attached to an underside of the base 22.
As shown in Figs. 2 and 3, when the wearer walks, the weight of the wearer presses the resilient plate 21 to move the second pin 2112 back and forth in the elongate slots 2214 of the bushes 2213, the resilient plate 21 moves up and down to absorb the shocks transferred from the ground. When the shoe is lifted from the ground, the resilient plate 21 bounces and the second pin 2112 moves forward.
Fig. 4 shows that two pairs of rollers 23 are rotatably connected to two ends of each of the first pin 2122 and the second pin 2112 by four respective bolts 231. As shown in Figs. 5 and 6, when the wearer rolls the rollers 23 against the ground, the weight of the wearer presses the resilient plate 21 to move the second pin 2112 back and forth in the elongate slots 2214 of the bushes 2213. The rollers 23 on the back of the second part 2 move backward and generate a forward force so that the wearer move forward. When the shoe is lifted from the ground, the resilient plate 21 bounces and the second pin 2112 moves forward.
Fig. 7 shows that the first part 1' can be made directly as a shoe with a sole 11' and a vamp 12' connected to the sole 11'. The user can easily wear the shoe.
When cooperated with rollers 23, the first part 1' can also be made directly as a shoe with a sole 11' and a vamp 12' connected to the sole 11'.

A second tubular portion 3111 is connected to the two clamp plates 3113 and a second pin 3122 extends through the second tubular portion 3111.
As shown in Figs. 10 and 11, when the wearer skates, the weight of the wearer presses the resilient plate 31 to move the second pin 3112 back and forth in the elongate slots 3211 in the ridges 321 so that the wearer moves forward. When the shoe is lifted from the ground, the resilient plate 31 bounces and the second pin 2112 moves forward.
A second part 2 includes a C-shaped resilient plate 21 and a top of the resilient plate 21 is fixed to an underside of the first part 1. The resilient plate 21 can be made by glass fibers, carbon fibers, plastic or metal strip.

The first pin 2122 pivotably extends through the two through holes 2224 of the two bushes 2223 in the two lugs 2221. Two lugs 2211 extend from the top of a rear end 221 of the base 22 and each lug 2211 has an elongate slot 2212 defined therethrough. Two bushes 2213 are engaged with the two elongate slots 2212 and each bush 2213 includes an elongate slot 2214. The second pin 2112 movably extends through the two elongate slots 2214 of the two bushes 2213 in the two lugs 2211. An outsole 223 is attached to an underside of the base 22.
As shown in Figs. 2 and 3, when the wearer walks, the weight of the wearer presses the resilient plate 21 to move the second pin 2112 back and forth in the elongate slots 2214 of the bushes 2213, the resilient plate 21 moves up and down to absorb the shocks transferred from the ground. When the shoe is lifted from the ground, the resilient plate 21 bounces and the second pin 2112 moves forward.
Fig. 4 shows that two pairs of rollers 23 are rotatably connected to two ends of each of the first pin 2122 and the second pin 2112 by four respective bolts 231.

A support unit 6 includes a resilient plate 61 which is received in the second part 52 and an insole 63 is put on the resilient plate 61. The resilient plate 61 includes a backward bent portion 614 extending from an underside of a front end thereof and a flexible protrusion extending from the underside of the rear end of the resilient plate 61. A pin 613 extends through the flexible protrusion 611. A fixed plate 62 is connected to an inner end of the second part 52 and includes two lugs 621 extending from a top of a rear end thereof.
Each lug 621 has an elongate slot 622 and the pin 613 movably extends through the elongate slots 622 of the two lugs 621. The backward bent portion 614 contacts the top of the front end of the fixed plate 62 so that the rear end of the resilient plate 61 moves up and down by movement of the pin 613 in the elongate slots 622.
When the wear walks, as shown in Figs. 18 and 19, the weight of the wearer presses the resilient plate 61, the underside of the backward bent portion 614 is pushed against the inner end of the second part 52 and the rear end of the flexible plate 61 is lowered so that the flexible protrusion 611 is pivoted to move the pin 613 backward in the elongate slots 622 to absorb the load of the wearer's weight. When the shoe is lifted from the ground, the resilient plate 61 and the flexible protrusion 611 bounce and the pin 613 moves forward.
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
