BACKGROUND OF THE INVENTION 
The conventional shoes having a resilient sole are generally provided with 
an elastic body disposed between the insole and the outsole thereof. Such 
conventional shoes as described above are generally limited in design in 
that they are provided respectively on the undersides of the front and the 
rear ends thereof with a relatively small area for making contact with the 
ground surface, and that they are incapable of providing their wearers 
with the state of balance so as to enable their wearers to keep themselves 
properly oriented or positioned, and further that they do not fit all foot 
sizes. 
SUMMARY OF THE INVENTION 
It is therefore the primary objective of the present invention to provide a 
shoe with a resilient sole which is provided respectively on the 
undersides of the front and the rear ends thereof with a relatively 
greater contact area, a better controllability and a better cushioning 
effect. 
It is another objective of the present invention to provide a shoe which 
has a resilient sole and can be worn adjustably by persons having 
different foot sizes, or by the growing children and youngsters. 
The foregoing objectives of the present invention are attained by the shoe 
comprising an insole, an outsole, and a resilient portion located between 
the insole and the outsole. The insole is provided integrally with a 
U-shaped ring portion which is in turn provided respectively and 
oppositely at both sides of the front end thereof with a front retaining 
hole and at both sides of the rear end thereof with a plurality of first 
rear retaining holes arranged in a parallel manner. The insole is further 
provided at the rear end thereof with a plurality of retaining portions 
arranged in a parallel manner. The outsole is provided respectively on the 
undersides of the front and the rear ends thereof with an anti-skidding 
piece. An adjustment piece of a U-shaped construction is provided 
respectively and correspondingly on both sides of the front end thereof 
with a second rear retaining hole. The adjustment piece is further 
provided on the bottom side thereof with a second retaining portion. The 
adjustment piece is fitted into the rear end portion of the U-shaped ring 
portion such that the second retaining portion is engaged with one of the 
first retaining portions of the insole, and that the second rear retaining 
hole of the adjustment piece is corresponding in location to one of the 
first rear retaining holes. 
The foregoing objectives, features, functions and advantages of the present 
invention will be more readily understood upon a thoughtful deliberation 
of the following detailed description of the present invention in 
conjunction with the accompanying drawings.

rear retaining holes 132 parallel to one another. The plate portion 11 is 
provided at the rear end thereof with three first retaining portions 14 
which are arranged side by side in a parallel manner and are of a round 
hole construction. The insole 10 is further provided on the side wall 
thereof with a plurality of holes 15. 
The outsole 20 is made integrally and provided with five tubular inner 
fitting portions 21 which are corresponding in location and number to the 
outer fitting portions 12 of the insole 10. The outsole 20 is further 
provided respectively at the front and the rear ends thereof with a recess 
22 which is so dimensioned as to receive therein an anti-skidding piece 23 
fastened thereto. The outsole 20 is still further provided on the side 
wall thereof with a plurality of holes 24. 
The resilient portion 30 comprises five coil springs 31 which are fitted 
respectively over the inner fitting portions 21 of the outsole 20 and the 
outer fitting portions 12 of the insole 10. The resilient portion 30 
further comprises a resilient casing 34 which has an outer wall 341. 
Located respectively at the upper side and the lower side of the outer 
wall 341 is an upright inner attaching portion 342 extending outwards. The 
inner attaching portion 342 is provided with a plurality of threaded holes 
343 corresponding in location to the holes 15 of the insole 10 or the 
holes 24 of the outsole 20. The resilient casing 34 is fastened with the 
insole 10 by a plurality of bolts engageable with the holes 15 and the 
threaded holes 343 of the upper attaching portion 342. The resilient 
casing 34 is further fastened with the outsole 20 by a plurality of bolts 
engageable with the holes 24 of the outsole 20 and the threaded holes 343 
of the lower attaching portion 342. 
The adjustment piece 40 is U-shaped in its cross section and is fitted into 
the rear end portion of the U-shaped ring portion 13 of the insole 10. The 
adjustment piece 40 is provided respectively on two opposite side walls 
thereof with a second rear retaining hole 41 and is further provided on 
the bottom wall thereof with a second retaining portion 42 of a tubular 
construction and engageable with any one of the first retaining portions 
14 of the insole 10. 
In combination, the adjustment piece 40 is disposed at the rear end of the 
ring portion 13 of the insole 10 such that the second retaining portion 42 
of the ajustment piece 40 is engaged with one of the first retaining 
portions 14 of the insole 10, and that the second rear retaining holes 41 
of the adjustment piece 40 are corresponding in location to the first rear

persons having different foot sizes to wear the shoe. The position 
adjustment of the adjustment piece 40 can be done easily by relocating 
manually the adjustment piece 40 such that the second retaining portion 42 
of the adjustment piece 40 is engaged with another first retaining portion 
14 of the insole 10. 
The bouncing effect of the shoe of the present invention is brought about 
by the coil springs 31 of the resilient portion 30. The shoe of the 
present invention enables its wearer to do a stable jumping motion, thanks 
to the anti-skidding pieces 23 of the outsole 20, which are made of a soft 
material and are deformable upon making contact with the ground so as to 
provide the outsole 20 with a better control area for mitigating the 
inertia impulse of a human body in motion. It must be noted here that the 
coil springs 31 of the resilient portion 30 may be replaced with a 
plurality of inflatable air sacs. 
As shown in FIG. 4, the second preferred embodiment of the present 
invention comprises the outsole 20 which is provided with a plurality of 
inner fitting portions 21 of a tubular construction. The inner fitting 
portions 21 are provided therein respectively with a cushioning rod 26 for 
regulating the compression of the coil spring 31 and providing the 
cushioning effect. 
As shown in FIG. 5, the third preferred embodiment of the present invention 
comprises four wheels 25 which are fastened with the outsole 20 to allow a 
person to coast on the shoe. 
The shoe of the present invention is unique in that it fits all foot sizes, 
and that the adjustment piece 40 can be relocated easily without the use 
of a hand tool, and further that the outsole 20 is provided with two 
anti-skidding means capable of preventing the skidding of the outsole 20 
and of providing the outsole 20 with the cushioning effect. 
The embodiments of the present invention described above are to be regarded 
in all respects as merely illustrative and not restrictive. Accordingly, 
the present invention may be embodied in other specific forms without 
deviating from the spirit thereof. The present invention is therefore to 
be limited only by the scope of the following appended claims.
