Abstract
Biomechanically, a human foot operates as a lever of the second class during the motions involved with walking, running or jumping. Extending the toes during such motion increases the distance between the fulcrum and effort of the foot-lever and results in increased foot propulsion. Disclosed are apparatus and related methods of accomplishing extended toes during the motions involved with walking, running or jumping
Description
- This application is a continuation of U.S. application Ser. No. 13/507,508 (field Jul. 5, 2012), which claims the benefit of Prov. Pat. App. Ser. No. 61/574,072 (filed Jul. 28, 2011), entitled “Fulcrum Athletic Shoe.” Both of these earlier filed applications are incorporated by reference in their entirety,
- Not applicable.
- Not applicable.
- The subject disclosure relates to athletic footwear, soles, insoles, inserts and slip-ons.
- During the motions involved with walking, running or jumping, the human foot operates as a second class lever to cause propulsion. This operation of a
foot 1000 is illustrated byFIGS. 1A and 1B . As shown in those figures, the weight of the body (or load) 2000 resting on thearch 1100 of thefoot 1000 is propelled byeffort 3000 from thecalf 1200 to raise the heel and leverage theweight 2000 against thetoes 1300, which act as afulcrum 4000. The propulsion caused by thefoot 1000 is equal to the amount ofeffort 3000 times the distance between the effort and the fulcrum. When thetoes 1300 of the foot are curled, as illustrated inFIG. 1A , thefulcrum 4000 is closer to theeffort 3000 than when thetoes 1300 are extended. The result is that that increasedfoot 1000 propulsion can be accomplished by operating thefoot 1000 with extended toes 1300 (FIG. 1B ) instead of curled toes 1300 (FIG. 1A ). - The ability to walk or fun faster and jump higher via increased foot propulsion is desirable because it advantageously increases athletic and exercise performance. However, the human toes naturally curl during walking, running or jumping movements so that, thus far, toe extension has only been achieved during the initial foot propulsion (e.g., via a starting block). Subsequent foot propulsions are naturally accomplished with curled toes. In view of the foregoing, a need exists for apparatus and related methods of increasing foot propulsion via continued toe extension.
- In the past several years there have been many advancements in the field of athletic footwear, but none of these advancements have been focused on increased foot propulsion. U.S. Pat. Nos. 5,257,470 and 5,253,435 to Auger, et al. discloses athletic footwear with inflatable and deflatable chambers and a built-in pump. The bladder systems focus on the metatarsal, arch and ankle portion for a custom fit that will increase comfort. However, the shoes do not inflate/deflate underneath the ball of foot and do not increase propulsion or facilitate continued toe extension. U.S. Pat. No. 2,086,389 to Pearson and U.S. Pat. No. 2,365,807 to Dialynas both teach an inflatable insole that fits under the arch of the foot. However, this does not affect the distance between the toes and heel of the foot or increase the amount of effort exerted by a user. U.S. Pat. No. 7,086,180 to Dolan, et al. teaches a fluid-filled bladder that provides traction, but does not move the fulcrum forward via toe extension, which is key to propulsion. As a result users of these types of footwear don't get the full explosive movements and propulsion out of their feet.
- Thus a need exists for an insole or footwear that moves the fulcrum or toes of the foot relative to the effort or heel of the foot during motion so that the result is increased athletic performance.
- It is an object of the present invention to create an athletic footwear that will engage the toes or phalanges of the foot, moving the fulcrum of the foot forward.
- It is an object of the present invention to create increased propulsion in the feet.
- It is a further object of the present invention to increase stride length while walking.
- It is a further object of the present invention to create a footwear that allows the wearer to run faster and jump higher.
- Other objectives and desires may become apparent to one of skill in the art after reading the below disclosure and viewing the associated figures. Also, These and other embodiments will become apparent from the drawings.
- The following represents brief descriptions of the drawings wherein:

Also, figures are not necessarily made to scale.
- Biomechanically, a human foot operates as a lever of the second class during the motions involved with walking, running or jumping. Extending the toes during such motion increases the distance between the fulcrum and effort of the foot-lever and results in increased foot propulsion. Disclosed are apparatus and related methods of accomplishing extended toes during the motions involved with walking, running or jumping.

FIG. 2 depicts the bottom of ahuman foot 1000.FIG. 3 depicts the bottom of ahuman foot 1000 with theball 1500 of thefoot 1000 divided into three sections. As seen inFIG. 3 , theball 1500 of thefoot 1000 may be divided into three areas, the upper third 1510, the middle third 1520, and the bottom third 1530. - Referring to
FIGS. 1A through 3 , the middle of thetoes 1310 are normally curved or curled. As alluded to above,FIG. 1A depicts what happens when a person pushes off on thetoes 1310 so that thefoot 1000 acts as a second-class lever. Thetoes 1300 act as a fulcrum, and theeffort 3000 is the lifting of thecalf 1200 muscles. As seen in FIG. 1A when a person pushes off on thetoes 1300, the middle of thetoes 1300 are usually not flattened. Instead the ball 1500 (FIG. 3 ) of the foot and the top 130 of the toes are engaged with the ground. The flattening of thetoes 1300, as shown inFIG. 1B , effectively moves thefulcrum 4000 of the lever forward or away from theeffort 3000. This increases the distance of the lever. The amount of propulsion generated from the lever is equal to the distance of the lever times the effort. Thus, when thetoes 1300 are Moved forward, the propulsion will increase even though the amount of effort remains the same. -
FIG. 4 depicts a typicalathletic shoe 200 with atypical insole 220. As shown inFIG. 4 , only theball 1500 of thefoot 100 and thetip 1310 of thetoes 1300 are in contact with theshoe 200insole 220 and the toes are free to curve or curl. - The preferred embodiment of the disclosure flattens or extends the toes to increase propulsion.
FIG. 5A is a top view the preferred embodiment of aninsole 400.FIG. 5B is a side view of theinsole 400. Theinsole 400 features an abrupt drop off 410 and aridge 420 surrounding the drop off 410. The drop off 410 preferably fits under the top third 1510 (FIG. 3 ) of the ball 1500 (FIG. 3 ) of the foot 1000 (FIG. 3 ). Theridge 420 supports the pads of the toes 1300 (FIG. 3 ).FIG. 8 depicts ashoe 200 with theinsole 400 ofFIG. 5 built into theshoe 200. Theinsole 400 ofFIGS. 5A and 5B is attached to the sole of theshoe 200 ofFIG. 8 via adhesive, sewing, melting, electrostatic welding, molding process, or another method known in the art. Theinsole 400 can also be manufactured as part of asock 300, as shown inFIG. 11 . Thesock 300 ofFIG. 11 can then be worn inside of a typical athletic shoe 200 (FIG. 8 ). - In the preferred embodiment, the
insole 400 is constructed from pliable materials. In preferred embodiment, theinsole 400 is manufactured with a “cookie cutter type process” (e.g. via a die and press arrangement) or cut (e.g. via a blade, scissors or laser) from flat sheets of the pliable material. However, theinsole 400 may also be constructed via any other manufacturing method known in the art. In the preferred embodiment, the thickness of theinsoles 400 is in the range between 3/16 of an inch to 1 inch. The range of with ¼ of an inch to ⅜ is the ideal thickness within that range, but other thicknesses may be used. Preferably, the length from the heel to the drop off 410 edge, is determined by the average heel to ball of foot length, although varying lengths may be available to accommodate different anatomies. -
FIG. 14 illustrates the strategic placement of a serrated orother edge 410 under the upper third 1510 (FIG. 3 ) of theball 1500 of thefoot 1000 in theinsole 400 ofFIG. 5A . This depicted placement allows thetoes 1300 to extended, and this moves the fulcrum of thefoot 1000 forward and increases propulsion. The pads of thetoes 1300 are supported by theinsole ridge 420 and this allows thetoes 1300 to be put in their most explosive propulsive position. - An alternate embodiment of the
insole 400 is theinsert 700 shown inFIG. 6A and 6B . This embodiment features a serrated orother edge 705 that preferably goes under the upper third 1510 (FIG. 3 ) of theball 1500 of thefoot 100.FIGS. 7A and 7B feature another embodiment of theinsole 800 with anedge 805 that features varying degrees of a severe drop off. This means that the angle A between the drop-off and the toe portion of the insole can be selected as an abrupt angle or a gradual angle or anything in between.FIG. 9 is a perspective view of theinsole 700 inside ashoe 200.FIG. 15 shows a side view of anathletic shoe 200 with theinsert 700 ofFIG. 9 .FIG. 10 is a perspective view of theinsole 800 inside ashoe 200.FIG. 16 shows a side view of anathletic shoe 200 with theinsert 800 ofFIG. 10 , Theinserts shoe 200 using enhanced, non-slip treatment to strengthen the grip of theinsert insert insert shoe 200 may be used. - In preferred embodiment, the
insoles FIGS. 6A and 6B , the thickness of theinsoles other edge ball 1500 of thefoot 1000, although varying lengths may be available to accommodate different anatomies. -
FIGS. 11 through 13 illustrate theinsoles sock 300. Thesock 300 can then be worn inside of a typicalathletic shoe 200. - Accordingly the reader will see that at least one of the embodiments illustrated provides the user the ability to change the fulcrum of the foot and the phalanges angle of launch point and increase its ability to propel said user.
- Other possible embodiments include:
- An athletic device constructed with no insole. The sole could be formed to interact with the balls of the foot and phalanges to increase the fulcrums propelling ability.
-
- An athletic device with an inflatable system under the pad of the toes and ball of the feet that adjusts to be rigid or collapses when desired.
- An athletic device under the pad of toes and/or under the bails of the foot that snaps back each step, with a spongy or collapsible area.
- An athletic device that forces the toes down upon push off into a rigid, but collapsible area under the toe.
- An athletic device that manipulates the heel, sole or parts of the upper third of the ball of the foot to move the fulcrum forward and engage the phalanges for more propulsion.
- A device similar to the disclosed embodiments, but with straps that can be put on the foot so that the device can be used independently.
