Definitions

  • This invention relates generally to footwear, and more particularly, to a shoe having incorporated therein a leaf spring-like member which is formed of a fiber-reinforced poly­meric material for absorbing and releasing energy during each step.
  • One well known approach utilizes resilient, spring-like arrangements which absorb and release energy during each step of walking or running.
  • the known arrangements store and release energy via resilient members which generally are arranged to operate in a direction which is generally orthogonal to the sole of the shoe so as to absorb and redistribute localized loads and forces.
  • U.S. Patent No. 4,492,046 describes a running shoe which has a spring wire arrangement disposed in a longitudinal slot in the sole.
  • the spring wire is arranged to urge the slot open ap­parently so that as the heel of the wearer comes downward, the slot is closed, and as the weight of the runner shifts forward onto the metatarsal heads, or ball, of the foot, the spring urges the upper section of the sole away from the lower section so as to assist in the weight shift.
  • Such assistance is stated in the patent reference as launching the runner into a comfortable stride.
  • this known arrangement is complex, heavy, and probably dangerous in that the heel end of the bottom of the shoe may cause the runner to trip and fall.
  • a further known spring-action running shoe is described in U.S. Patent No. 4,534,124 which shows an athletic shoe coupled at its toe end to a leaf spring; the leaf spring being coupled at its rearward end to a further, lower sole.
  • the running shoe proper is arranged parallel and at some distance with respect to the lower sole such that any weight being applied to the running shoe would result in a storage of energy in the leaf spring.
  • a structure is heavy, bulky, complicated, and accident-prone.
  • this invention provides a shoes having a leaf spring-like flexible resilient member arranged in the vicinity of the sole of the shoe.
  • the flexible resilient member has a predetermined flexure characteristic and is arranged to flex with the sole of the shoe, in the region of the ball of the foot of the human wearer, during each step.
  • the material which may be a fiber-reinforced polymeric material, stores and releases energy in response to such flexure during each step.
  • the material which forms the flexible resilient member may be a carbon fiber reinforced epoxy which is formed of a plurality of layers.
  • the configura­tion and thickness of each layer, as well as the number of such layers can be selected to form the predetermined flexure charac­teristic.
  • the flexible resilient member is adapted to the weight and other characteristics of the wearer.
  • the various layers are bonded to one another. Additionally, the entire flexible resilient member may be interposed between an outer sole of the shoe and an inner sole thereof which communicates with the foot of the wearer.
  • Each layer of fiber-reinforced polymeric material may have a flexure characteristic which is directional resulting from the orientation of the reinforcing fibers within the material. Typically, such material can withstand greater forces, such as bending forces, in the direction of the fiber orientation, than transverse thereto.
  • the various layers of fiber-reinforced material which form the flexible resilient member may each have a directional aspect to the flexure characteristic. Such layers may be arranged so that the directions of the fiber orientation are at respective angles to one another. In this manner, the longitudinal and transverse flexure characteristics of the flexible resilient member can be tailored for a specific activity in which the human wearer is expected to engage.
  • the layers are arranged such that the fiber orientation of some of the layers is longitudinal with the shoe, while other such layers are at 45° to either side thereof.
  • the flexible resilient member will be stiffer in the longitudinal direction.
  • the stiffness of the flexible resilient member can be tailored to specific applications by varying the number of layers of fiber-reinforced material, as well as the angular orientations of the layers.
  • the particular flexure characteristic to be incorporated in any given shoe should be tailored to the weight of the wearer, the running style of the wearer, the nature of the particular activity in which the wearer is expected to engage, and the characteristics of the surface on which such activity will take place.
  • a heavy runner will require a fairly stiff flexible resilient member, and therefore the flexible resilient member of a shoe tailored for such a runner would be formed with a greater number of layers of carbon fiber material, irrespective of shoe size.
  • sprinters will require stiffer flexible resilient members than marathon runners, since sprinting imposes greater forces and inertial loads on the foot of the runner than slower running, such as marathon running.
  • Football players who generally are heavy athletes and are required to sprint, would require rela­tively stiff resilient members in their shoes.
  • the present invention is premised at least partially on the recognition by the inventor herein that the achievement of effectual energy return for a runner, sufficient to improve the performance of the wearer in a given activity, requires shoes having incorporated therein resilient, spring-like members which are significantly stiffer, or more resistant to flexing, than conventional athletic shoes.
  • This understanding requires acceptance of a premise which is entirely contrary to the approach accepted by present day shoe designers and manufact­urers.
  • the flexible resilient member is formed of plural layers of carbon fiber material which may be cast in a solidifying mate­rial, such as epoxy.
  • a solidifying mate­rial such as epoxy.
  • transverse stiffness it is desired, in a running shoe embodiment of the inven­tion, to minimize transverse stiffness. Although significant amounts of transverse stiffness can be avoided by aligning the fibers of the carbon layers longitudinally with respect to the foot of the user, the resulting absence of transverse support will permit the epoxy of the casting to fracture in a direction along the carbon fibers. Thus, in a practical embodiment a compromise is achieved by orienting the carbon fiber layers at predetermined angles with respect to one another, whereby they layers are arranged at offsets corresponding to rotations of approximately 10° from the longitudinal axis.
  • the resilient spring-like member is formed of four layers of carbon fiber material.
  • the first layer is arranged so that its aligned carbon fibers are disposed at a 10° counter clockwise orientation (+10°) with respect to the longitudinal axis, and the second layer is arranged at a 10° clockwise orientation (-10°).
  • the third and fourth layers are arranged at -10° and +10°, respectively.
  • a shoe constructed using the flexible resilient member described hereinabove is thus tuned, in the sense of energy storage and return, within a range which would achieve the advantages of the present invention for a broad segment of the population.
  • the tuning of shoes for specific individuals can be achieved in a variety of ways, including using different numbers of carbon fiber layers in the resilient member. For example, for sizes 4 to 8, two or three carbon fiber layers may be used.
  • the shoe of the present invention is not as flexible as conventional running shoes. Moreover, certain embodiments of the inventive shoe may be heavier than conventional shoes. Thus, the advantages of the present invention are achieved in a manner which seems contrary to the current thinking of those skilled in the art of shoe manufacture.
  • transverse stiffness may not be desirable in running shoes. Substantial transverse stiffness will exaggerate the wearer's tendency toward pronation, which is manifest as a rapid medial shift in the center of pressure immediately after the heel strikes the ground during running. There are, however, activities such as tennis or basketball which require the participant to apply high transverse loads, part­icularly during rapid changes in direction.
  • shoes constructed for these types of activities are preferably provided with significant lateral stiffness, which can be achieved by increasing the angles of orientation of the aligned carbon fibers from approximately ⁇ 10° to ⁇ 90°.
  • the flexible resilient member will be generally planar and extend only throughout the foremost two-­thirds of the shoe.
  • the heel portion of such a shoe could be provided with a cushioning material which will absorb and redistribute shock forces and loads.
  • the flexible resilient member extends throughout the length of the shoe and can serve the same function at the heel of the shoe as described hereinabove for flexure in the region of the metatarsal heads of the foot of the wearer.
  • the flexible resilient member need not be entirely planar, and instead may be curved in a manner which conforms to the sole of the shoe. For example, the flexible resilient member may be curved upward in the region of the front of the shoe.
  • the rear portion of the shoe may be provided with a spacer formed of a resilient damping material.
  • a spacer may be formed of a cushioning material, including a commercially available force distributing material marketed under the trade name Sorbothane. When subjected to a shock-type load, this material functions somewhat as a liquid in that it distributes the load throughout itself. This has the effect of reducing the overall shock force experienced by any given point in the region of the heel of the foot of the wearer of the inventive shoe.
  • an inner sole is provided to prevent communication of the foot of the wearer directly with the flexible member. Such direct communication could result in bruising or other injury to the foot of the wearer, particularly in the region of the metatarsal heads. Elimination or reduction of this type of injury can result in significant improvement in the wearer's athletic performance.
  • certain embodiments of the invention may be provided with a metatarsal pad which is located on the inner sole in a region thereof which corresponds to a location immediately behind the metatarsal heads of the foot of the wearer. Such a metatar­sal pad has the effect of lifting the foot slightly so as to ease the load on the metatarsal heads. This, of course, can reduce fatigue and improve performance.
  • the inner sole may be provided with a metatarsal cushion located immediately beneath the metatarsal heads. Such a cushion would serve to distribute more evenly the forces applied to the metatarsal heads.
  • the flexible resilient member cooperates with the outer sole and the heel of the shoe to achieve a tuned response.
  • the flexible resilient member functions as a spring, while the outer sole and heel operate as a damping medium.
  • the inner sole can also function as a damping medium.
  • the damping media may assist in reducing one or more oscillation modes of the shock wave produced in a runner's leg by the impact at foot-strike and also may assist in tuning the system for the particular running characteristics of the wearer.
  • cushioning material in this region can served to dampen oscillations as described hereinabove.
  • FIG. 1 is a cross-sectional representation of a shoe 10 constructed in accordance with the invention.
  • shoe 10 has an upper portion 11 which may be constructed in a manner which is known in the art.
  • the shoe has an outer sole 12 which, in this embodiment, serves as the outermost bottom layer.
  • a flexible resilient member 13 is arranged to communicate with outer sole 12 and extends throughout the front portion of the shoe.
  • a cushion spacer 15 communicates with the outer sole and serves to dampen and distribute shock forces which are created when the heel portion of the shoe is urged into communication with the ground (not shown) during running.
  • cushion spacer 15 serves to retain the flexible resilient member in place and avoid its shifting backward.
  • the flexible resilient member and the cushion spacer are covered, in this embodiment, by an insole 16.
  • this embodiment is provided with a soft cushion layer 17.
  • the insole and the cushion layer serve to provide comfort to the wearer, while also protecting the foot of the wearer from direct com­munication with the flexible resilient member.
  • cushion layer 17 is provided with additional thick­ness in the vicinity of the heel portion of the shoe. This extra thickness provides an additional cushioning support which reduced transmission of peak forces during running to the heel of the wearer.
  • FIG. 2 is a cross-sectional representation of a shoe 20 constructed in accordance with the invention so as to have removable components.
  • This shoe has an upper portion 21 which may be of conventional construction. Additionally, the shoe is provided with an outer sole 22 and a flexible resilient member 23. However, in this embodiment, an inner sole 24 is in direct communication with outer sole 22 and is interposed between the outer sole and the flexible resilient member.
  • a cushion spacer 25 is provided in the heel region of the shoe. However, unlike the embodiment of FIG. 1, the cushion spacer and the flexible resilient member in the embodiment of FIG. 2 are removable. When thus removed, shoe 20 can be used as a conventional shoe, with the foot of the wearer communicating directly with insole 24. Cushion spacer 25 is shown to couple with the flexible resilient member.
  • a soft cushion insole 27 is provided on top of the flexible resilient member and the cushion spacer.
  • cushion layer 27 is removable, thereby permitting access to the removable flexible resilient member and cushion spacer.
  • FIGS. 3 and 4 are side and top plan views of an illustrative embodiment of a cushion insole 30 which is suitable for use with the shoe embodiments of FIGS. 1 and 2.
  • Cushion insole 30 can be formed in a conventional manner.
  • a metatarsal pad 32 which is arranged on the cushion insole in a region thereof corresponding to a position immediately behind the metatarsal heads of the foot of the wearer.
  • the cushion insole is provided with a metatarsal cushion 33 which is located so as to communicate with the metatarsal heads of the foot of the wearer.
  • metatarsal cushion 33 is of the same thickness as the rest of the cushion insole.
  • FIG. 5 is a cross-sectional representation of a shoe 50 constructed in accordance with the invention and utilizing the insole described hereinabove with respect to FIGS. 3 and 4.
  • This embodiment of the invention has an outer sole 52, immediately above which is arranged a flexible resilient member 53.
  • the flexible resilient member extends for only a portion of the length of the shoe, there being provided a cushion spacer 55 which operates in the manner described hereinabove with respect to the cushion spacers of FIGS. 1 and 2.
  • the cushion spacer may be formed of a viscous material which cushions the heel and also serves to dampen oscillations of the flexible resilient member.
  • the flexible resilient member can extend to the rear of shoe 50 , thereby obviating the need for cushion spacer 55.
  • outer sole 52, and possibly an inner sole 56 all cooperate with the foot of the wearer to dampen any oscillations in the flexible resilient member.
  • flexible resilient member 53 has a predetermined curvature which can add a measure of comfort to the wearer.
  • This embodiment of the invention utilizes a removable cushion insert 30 , as described hereinabove with respect to Figs. 3 and 4. As shown in FIG. 5, cushion insole 30 conforms to the curvature of the shoe.
