Definitions
- This invention generally relates to footwear and more particularly to shoes for use in athletics and rehabilitation that are tailored for a specific activity and a level of the wearer's expertise for that activity.
- Shoes suited for physical activities such as running, jogging, brisk walking, aerobic exercise and the like which involve stepping and landing on an individual's feet are well known. Generally these activities are characterized by suspension and landing of the foot. In such physical activities the individual's foot acts as a shock absorber upon landing, a support member during the period between landing and stepping off, and a spring for propelling, launching, or stepping from the surface such as the ground.
- injuries incurred during such activities continue to be widespread. Such injuries include heal spurs, plantar fascia, shin splints, and stress fractures of the sesamoid bones and head of the metatarsal bones, as well as metatarsalgia.
- Forefoot landings as opposed to heel landings, have proven to be the most efficient landing pattern during physical activities that involve such stepping off and landing.
- the landing forces are applied generally to the dynamic front part of the foot, or forefoot, comprising the toes and the ball of the foot simultaneously.
- the intrinsic muscles of the foot and the skeletal structure including the gastrocnemius, Soleus, Plantaris, Tibialis Posterior, Flexor Halluces, Peroneus Longus and Brevis place the arch of the foot in a proper attitude to act as a shock absorbing spring as the forefoot impacts a support surface.
- stepping off from the forefoot without initial heel contact tends to increase efficiency as there is no effort expended to roll the foot from the heel to the toe.
- Forefoot landings also reduce the strain on the musculoskeletal structure.
- individuals also must consciously attempt to land on the forefoot. Frequently they revert to a heel landing when they become fatigued or otherwise distracted or preoccupied.
- Penka for a heelless athletic shoe which enhances forefoot landing during various physical activities, inhibits heel landings, enhances an individual's performance and does not cause the foot to undergo unnecessary and potentially dangerous dorsiflexion from the step off to the pre-landing phase.
- Penka also provides a shoe that is adapted for use during rehabilitation from injuries caused by heel-to-toe landing patterns and encourages pre-disposition of the foot for landing on and immediate stepping off from the forefoot while not placing undue tension on the Gastrocnemius-Soleus muscle and the Achilles tendon.
- Such a shoe has an upper and a multiple part lower sole forming an interior volume for receiving an individual's foot.
- the multiple part sole comprises an inner sole, a midsole and an outer sole.
- the inner sole engages the plantar surface of the foot.
- the midsole is relatively rigid and attaches to the exterior of the inner sole to be coextensive with at least a portion of the forefoot and supports the plantar surface of the foot.
- the front or proximal section of the outer sole may have a different thickness according to different embodiments of this invention which underlies at least a portion of the forefoot and a contiguous rear portion for underlying the heel.
- the front section provides a landing surface for the shoe.
- the rear portion is thinner than the landing surface whereby an exterior surface of the rear portion is elevated relative to the landing surface thereby to prevent heel landings.
- the prior art does not specify the depth or thickness and the length of the recess area appropriate for different individuals who engage in different types of activities at different levels of skill.
- This lack of specification is leading to a new trend of musculoskeletal injuries such as calf reaction, plantar fascia, metatarsalagia and the cuboid syndromes.
- the recess area of the heel must be clearly defined in depth, length and thickness of the sole of the shoe.
- Another object of the invention is to enhance the performance of the wearer of such a shoe in their activity of choice.
- Still another object of the invention is to provide previously unavailable embodiments for an athletic shoe or shoes suited for rehabilitation of individuals with various types of injuries or conditions.
- an embodiment of a heelless shoe has an upper including a toe portion, a midsection and a rear portion and a multiple part sole forming an interior volume for receiving an individual's foot.
- the multiple part sole comprises an inner sole for engaging the plantar surface of the foot, a midsole having an inner surface attached to the exterior of the inner sole to be substantially coextensive with the inner sole, the midsole having an outer surface, and an outer sole attached to the outer surface of the midsole intermediate the inner and outer soles.
- the outer sole has a first portion extending from the proximal end of the shoe to a position under the foot selected according to an intended use of the shoe and a second contiguous portion extending from the selected position to the distal or rear portion of the shoe.
- the first portion of the outer sole provides a landing surface for the shoe and the second, relatively thin portion as compared to the first portion thereby inhibiting landings on the heel for different embodiments of the shoe and generally promoting an appropriate posture or gait for the wearer while performing the motions involved in the selected activity.
- FIG. 1 is a side external view of a shoe in accordance with this invention
- FIG. 2 is a side cross sectional view of the embodiment of the shoe shown in FIG. 1 ;
- FIG. 3 is a table that is useful in understanding this invention.
- FIGS. 4A through 4F are views illustrating various embodiments of the present invention as related to the anatomical structure of a foot for different applications;
- FIG. 5 is a side cross sectional view of an embodiment of the invention.
- FIG. 6 is a side cross sectional view of another embodiment of the invention.
- a shoe 10 includes an upper 11 that attaches to a multiple part sole 12 to define a volume for receiving an individual's foot with a toe box 13 , a heel box 14 , and an intermediate section 15 .
- the multiple part sole 12 comprises an inner sole 16 , a midsole 17 and an outer sole 20 .
- a first portion 21 of the outer sole 20 defines a landing surface 22 for engaging a support surface 23 formed by the ground, floor or the like.
- Rearward end 24 of the midsole 17 and rearward end 25 of the outer sole 20 and the first portion 21 respectively, underlie a portion of the intermediate section 15 proximate the heel box 14 .
- a relatively thin rear or second portion 28 of the outer sole 20 extends from the rearward end 25 to underlie the heel box 14 and define an exposed recessed surface 30 under the heel that is elevated from the support surface when the shoe 10 is in a normal resting position as shown in FIG. 1 .
- This construction in combination with the mechanics of the ankle and foot minimize heel contact before the landing surface 22 contacts the support surface 23 .
- the upper 11 as depicted in FIG. 1 may have any conventional construction depending upon seasonal factors, foot conditions and other criteria.
- the upper 11 comprises a substantially standard upper with laces 31 for securing the shoe 10 on an individual's foot 32 ( FIG. 2 ).
- the upper 11 defines an access aperture 34 through which the individual's ankle 35 extends.
- Materials for forming the upper 11 can include, for example, canvas, leather or plastic materials.
- Velcro® strips or other tying arrangements can be substituted for the laces. The shoe could even be constructed as a loafer with no tying arrangement.
- the inner sole 16 extends from a front or toe end 36 of the toe box 13 through the heel box 14 and has an upper or inner surface 37 and a lower or outer surface 38 .
- the upper surface 37 engages a plantar surface 39 of the foot 32 .
- the lower surface 38 abuts an upper surface 40 of the midsole 17 .
- Upper heel surface portion of the outer sole 20 extends back beyond the midsole 17 .
- the inner sole 16 preferably comprises a thin layer of relatively soft material that resiliently deforms to correspond to both the shapes of the overlying plantar surface 39 and the underlying surface 40 and surface portions 41 and 42 .
- a soft, thin foam having an open cell construction is an example.
- the midsole 17 preferably comprises a material that is relatively hard with some elasticity such as various natural and synthetic cellular foam with small apertures or like.
- a closed cell, elastic, pressure deformable foam is an example.
- the midsole 17 underlies a portion of the toe box 13 and the intermediate section 15 , preferably from a front end 43 proximate the distal phalanges 45 to the rearward end 24 underlying an area corresponding to the Calcaneum bone 50 .
- the outer sole 20 underlies the entirety of the shoe 10 and may even wrap around leading and trailing ends 51 and 52 of the upper 11 .
- the second portion 28 is preferably thin compared to the combined thicknesses of the rearward ends 24 and 25 to avoid friction tear.
- the recessed surface 30 thus remains substantially spaced from the support surface 23 upon initial contact by the landing surface 22 during walking, running, jogging or other similar activities.
- the second portion 28 is preferably formed of a substantially rigid, hard material, such as a non-elastic rubber or any of various plastic compounds that tend not to deflect under pressure loads associated with use of the shoe 10 . Consequently, the second portion 28 firmly supports an individual's heel 47 through the inner sole 16 while maintaining the spacing from the support surface 23 .
- the first portion 21 including the landing surface 22 is preferably formed of a softer, more flexible or elastic material, such as other known rubber or plastic compounds to provide more cushioning while also providing support and durability during use.
- the spacing, or recess depth D in FIG. 1 , of the second portion 28 above the support surface 23 is based upon a number of considerations. These include the normal range of foot movement, typically 20° in dorsiflexion, shoe size, body weight, and type of activity in which the individual intends to engage, skill level and any limitations particular to the individual by whom the shoe is to be worn.
- a range of values for a length, L, of the outer isole 20 and a recess depth D suited to a typical individual for use during participation in certain common activities define different values.
- the length L represents the distance from the front end 36 of the toe box 13 rearward to the beginning 55 of the recessed portion 28 of the outer sole 20 .
- L T represents the full length of the shoe 10 from the tip of the toe 36 to the back of the heel 57 .
- the length L suited for a given individual may vary from the distance “a” between the front end 36 of the toe box 13 to the apex of the Calcaneus 47 , to shorter lengths b, c, d, e or f corresponding to termination 55 of the landing surface 22 optimized according to the intended use of the wearer in a particular type of activity.
- the approximate percentage of the length L of the first part of the outer sole 20 relative to the full length of the shoe L T is given in FIG. 3 .
- the midsole 17 of the shoe between the inner sole 16 and outer sole 20 is not illustrated in FIG. 4 for simplification.
- the skeletal structure of the foot is shown as it would be positioned inside the shoe as viewed from the inside of the foot so as to particularly show the medial arch 59 which comprises the metatarsal bone 61 , the cuneiform 63 , the navicular 65 , the talus 67 , the calcaneus 50 and associated connective tissue ( FIG. 2 ).
- the landing surface 22 is still longer since the weight of the body is typically pressing further back towards the heel of the foot during landing and the greater length of the landing surface 22 provides for cushioning of the foot from landing through transfer of the body weight forward during motion through stepping off while preventing potentially harmful heel strikes.
- the length L of the landing surface is decreased for an individual engaging in an activity in which the person's weight lands further forward on the forefoot.
- the length of the landing surface as given in FIG. 3 is generally reduced and the depth of recess D for the shoe constructed to correspond to the higher end of the ranges specified. This additional thickness provides for some cushioning. Also, the thickness of the landing surface and the corresponding depth of recess D are greater for a skilled athlete than for a beginner.
- the different lengths L of the landing surface 22 correspond to anatomical features of the individual's foot inside the shoe as illustrated in FIG. 4A .
- the first part of the outer sole extends from the tip of the toes 36 rearward to the region underneath the apex 47 of the calcaneus 50 .
- the recessed heel portion helps to prevent heel strikes and promotes better posture.
- Such shoes are intended for competitive athletes with a reasonable degree of fitness and, as explained above, can enhance the performance of the wearer by capitalizing on the natural “springiness” of the forefoot landing and the quick landing and stepping off.
- a sprinter's heel should never touch the ground and a bulky heel cushion is a disadvantage.
- FIG. 3 the corresponding depth of recess D in FIG. 3
- a shoe according to this invention may be further customized for an individual based on various factors and the full range of values for the length L are contemplated between those illustrated in FIG. 4 . It should now be apparent that the actual length L (see FIG. 3 ) selected for a particular individual's foot will be determined by the actual size of the individual's foot and be informed by a professional fitting the shoe and by the preferences of the wearer.
