AI Technical Summary

Benefits of technology

The present invention is about providing better shock absorbing properties to footwear and giving lift and propulsion to the foot of the wearer while walking or running. This is achieved by using coil springs and magnetic springs together designed to support an air-flux gap within the sole member at all times, which permits continuous and more effective shock dissipation. The shock absorbing insert of this invention can be used in any type of footwear and significantly reduces shock to the body while walking, running or in other types of foot motion, and adds lift and propulsion, thereby reducing fatigue. Flexible and easily replaceable, the spring insert in the heel is the technical effect of this invention.

Problems solved by technology

Some of these structures are bulky and heavy, or cannot effectively be manufactured.
One problem with prior shock absorbing footwear, including my own, is that the characteristics of the shock absorber, particularly including the load capacity, cannot be easily adjusted.

Embodiment Construction

[0023]As shown in FIGS. 1 and 2, which depict two embodiments of the invention, shock absorbing footwear embodying the invention includes an outsole 10, an insole 20, and an insert assembly 30.

[0024]The outsole 10 is preferably made of rubber, EVA, composite or polyurethane. It has an open heel cavity or a similar cavity beneath the ball of the foot, approximately as wide as the heel or ball, 2.5″ for example.FIG. 2 shows the heel cavity only, as an example. The reader will understand that the principles illustrated can easily be adapted to an insert placed beneath the ball of the foot (as suggested in FIG. 1) rather than—or in addition to—at the heel location.

[0025]The heel cavity has an opening on one side, e.g., toward to the arch or heel, approximately 3.0″ wide, for receiving the insert assembly.

[0026]The outsole has a perimeter bead made of rubber, eva, composite or polyurethane. Alternatively, it may have multiple beads (upper and lower) to allow the insert to be manually pre...

Abstract

An article of footwear has a shock absorbing insert placed between the insole and the outsole thereof, for example at the heel. The insert includes a spring carrier having upper and lower portions, each having a plurality seats for receiving a respective ends of respective coil springs. Each of the springs extends between said upper and lower portions and is captured therebetween. A magnetic spring supplements the mechanical springs. The springs and carrier are protected from environmental elements and abrasive particles by a debris shield.

Description

[0001]This application claims benefit of provisional application 61 / 957910, filed Jul. 15, 2013.BACKGROUND OF THE INVENTION[0002]This invention relates to shock absorbing footwear.[0003]Numerous footwear inventions have been proposed for absorbing shock and adding lift, particularly in the athletic shoe field. For example, U.S. Pat. No. 4,817,304 describes footwear with a cushioning sole structure in which a sealed internal member in the sole is inflated with gas to form a resilient insert in the heel region of the shoe. Various shoe structures have also been proposed in which springs are embedded in the shoe sole in the heel region or over the entire sole. See, for example, U.S. Pat. No. 5,502,901, No. 5,138,776, No. 4,566,206, and No. 4,592,153. Some of these structures are bulky and heavy, or cannot effectively be manufactured. My own patents (U.S. Pat. Nos. 5,502,901 and 7,213,350) describe improvements over those prior patents.[0004]One problem with prior shock absorbing footwe...
