A shock absorption and energy return assembly for increasing the stability, shock absorption and energy return capabilities of a shoe. The assembly generally includes lower and upper guide members having a plurality of spring retainers, a plurality of springs positioned within the spring retainers, and a resilient connecting member which fixedly attaches the lower guide member to the upper guide member and serves to limit the separation between the guide members, preventing disengagement of the springs from within the guide members while simultaneously providing a means of allowing the springs to compress below their uncompressed height when a force is applied on the assembly. Alternatively, the assembly could be surrounded by a sealed, transparent encasement, which in one embodiment would comprise a lower portion and an upper portion surrounding the lower guide member and the upper guide member, and a plurality of lower extrusions and upper extrusions. The extrusions would extend into a plurality of apertures contained within the guide members as well as the plurality of compression springs positioned between the guide members, and would be adjoined. The encasement may also be filled with a pressurized gas for added stability and dampening of the springs. The inventive device is designed to be inserted or molded within the heel or forefoot portion of the mid-sole of a shoe, with the mid-sole optionally having one or more cutouts, thereby allowing a means of viewing the inventive device in operation.

The article of footwear incorporating a shock absorption and energy return assembly of claim 2 wherein the lower guide member of the forward shock absorption and energy return assembly is integrally attached to the lower guide member of the rear shock absorption and energy return assembly by a medial connecting member. 4. The article of footwear incorporating a shock absorption and energy return assembly of claim 1, wherein said mid-sole has one or more openings to provide a means of viewing the assembly. 5. The article of footwear incorporating a shock absorption and energy return assembly of claim 1, wherein said assembly is surrounded by a sealed transparent encasement made of a flexibly resilient material. 6. The article of footwear incorporating a shock absorption and energy return assembly of claim 5, wherein said sealed encasement contains a pressurized gas. 7. The article of footwear incorporating a shock absorption and energy return assembly of claim 1, wherein the springs positioned at a medial portion of the sagittal plane of the assembly are of a different spring rate than the springs of the lateral portion, providing for a means of pronation control to the footwear. 8. The article of footwear incorporating a shock absorption and energy return assembly of claim 1, wherein the springs positioned at a lateral portion of the sagittal plane of the assembly are of a different spring rate than the springs of the medial portion, providing for a means of supination control to the footwear. 9. An article of footwear which includes an upper, a mid-sole attached to the upper, and an out-sole, said mid-sole incorporating a shock absorption and energy return assembly comprising:a resiliently strong lower guide member including a plurality of spring retainer cavities;a resiliently strong upper guide member including a plurality of spring retainer cavities;a plurality of springs positioned between said lower guide member and upper guide member, whereinsaid lower guide member is fixedly attached to said upper guide member by way of a resilient connecting member, andsaid assembly is surrounded by a resilient encasement having a lower portion and an upper portion, whereinsaid encasement includes a plurality of extrusions extending from said lower portion and a corresponding plurality of extrusions extending from said upper portion, whereinsaid lower guide member includes a plurality of apertures and said upper guide member includes a plurality of apertures, whereas said apertures receive said extrusions, wherein said extrusions extend into said plurality of springs, and said plurality of extrusions are adjoined. 10. The article of footwear incorporating a shock absorption and energy return assembly of claim 9, wherein at least one extrusion from the lower portion is connected to one extrusion of the upper portion to form a support portion. 11. The article of footwear incorporating a shock absorption and energy return assembly of claim 9, wherein there is more than one resilient connecting member. 12. The article of footwear incorporating a shock absorption and energy return assembly of claim 9, wherein the resilient connecting member is an elastically deformable element including one or more apertures, whereas one or more said extrusions extending from said lower portion, and one or more extrusions extending from said upper portion, extend into said apertures and are adjoined. 13. The article of footwear incorporating a shock absorption and energy return assembly of claim 9, wherein the resilient connecting member contains a horizontal aperture located through a central axis of its diameter to allow insertion of an air insertion nozzle used in the manufacturing process. 14. The article of footwear incorporating a shock absorption and energy return assembly of claim 9, wherein the springs positioned at a medial portion of the sagittal plane of the assembly are of a different spring rate than the springs of the lateral portion, providing for a means of pronation control to the footwear. 15. The article of footwear incorporating a shock absorption and energy return assembly of claim 9, wherein the springs positioned at a lateral portion of the sagittal plane of the assembly are of a different spring rate than the springs of the medial portion, providing for a means of supination control to the footwear.
