THERAPEUTIC INSOLES AND FOOTWEAR

RELATED APPLICATIONS

[0001] This application claims the benefit of U.S. Application No. 62/380,485, entitled "Footpad Insert," and filed on August 29, 2016, and U.S. Application No. 62/424,519, entitled "Footpad Insert," and filed on November 20, 2016, both of which are

incorporated herein by reference in their entirety for all purposes.

BACKGROUND

[0002] Plantar fasciitis results in about 1 million patient visits per year to medical professionals. Treatment of plantar fasciitis is estimated to cost between $192 and $376 million dollars annually for treatments such as injections, surgeries, steroids and physical therapy. Average recovery time for plantar fasciitis can be as long as 6 weeks.

Reoccurrence of plantar fasciitis is not uncommon. There are also likely a large number of unreported cases of plantar fasciitis and/or related conditions for which afflicted people seek over the counter treatments such as new shoes, shoe inserts, massage therapy and other stretching aids or tools used for comfort and treatment.

[0003] The plantar fascia is a thick band of ligament located at the bottom of the foot that contributes to supporting the arch of the foot. There are many factors that can cause the arch to fall, and some may lead to formation of scar tissue at the bottom of the heel. Pain in and around the heel is a common complaint and the heel area tends to be a source of pain. Chronic scar tissue may not respond to conventional treatments or modalities. [0004] Plantar fasciitis can include degeneration and localized inflammation of the proximal fascia (the part closest to the heel). Plantar fasciitis is bilateral (in both feet) in up to a 1/3 of cases, and about 10% of plantar fasciitis cases may be a result of running injuries. Unfortunately, if not treated right plantar fasciitis can last for months or years, and can be a debilitating condition.

[0005] Fasciitis can occur when the fascia is overloaded from tight calves or Achilles tendons, a sudden increase in activity or training, poor footwear (e.g., worn or over- flexible running shoes), a hard training surface, an arch being too high or too low, and/or a weight increase.

[0006] This overload can produce excessive stress on the fascia, which can result in a number of small tears in the fascia tissue. The tears can cause the body to go into a protective mode and start an inflammatory healing reaction, which can make the fascia thicker, less flexible, more sensitive, and painful. If plantar fasciitis is not treated properly, an afflicted person can get stuck in a chronic inflammatory phase, which can be frustrating and painful.

[0007] Shoe inserts are widely available devices that are useful can also be specifically designed orthotic devices used to relieve painful conditions, such as corns, calluses, metatarsal conditions, or other painful conditions of the foot. Over-the-counter shoe inserts are relatively inexpensive but can provide limited relief of many conditions. It is important to note that there are few, if any readily available devices specifically to address this condition of plantar fasciitis. Specially designed orthotics can provide more relief, but are expensive and inconvenient to replace. [0008] Other foot wearing items that support or aid in plantar fasciitis are as one unit, attached to footwear. It is not easily transported into other footwear. You are very limited to when and where you can wear them. There are other concepts such as foot wraps or compression wear that can be uncomfortable and or expose strapping, wrapping or Velcro, which may not be acceptable to users due to aesthetic and/or dress code considerations.

[0009] Accordingly, there remains a need in the art for footpad inserts/insoles that are relatively inexpensive, widely available, provide relief for a wide range of painful and/or damaging foot conditions, and that easily provide therapeutic benefits to a wide range of users with a wide range of conditions affecting the foot. The present invention meets this need.

[0010] Some implementations were conceived in light of the above-mentioned problems and limitations.

SUMMARY

[0011] Plantar- Fasciitis is a tough layer of connective tissue that supports the arch and runs from the heel to the ball of the foot. The plantar footpad has weight bearing, solid pods embedded to create maximum resistance and pressure while standing or walking. The results can include trigger point therapy and plantar fasciitis benefits such as helping break up the soft connective tissue in the foot, which can help promote blood flow to the area, aiding, restoring and rebuilding the fascia in the foot. The embedded pods can be arranged and configured in the insole to trigger the areas where plantar fasciitis conditions or symptoms are prevalent. The embedded pods can range in size, shape, diameter, height and composition, depending on placement and configuration as well as depth and material of footpad. Insoles in accordance with some implementations can be inserted into other footwear of choice and can be used as frequently as needed. Insoles and footwear can include one or more weight bearing, spherical embedded pods that provide pressure on the trigger points as a user walks or stands. The pods can help stimulate areas associated with problematic foot issues such as plantar fasciitis. Because the spherical (or semi- spherical) pods are embedded in and through the insoles and footwear, the pods provide pressure to trigger points as well as breaking through fascia to promote blood flow to aid in restoring the fascia in the foot.

[0012] Some implementations can include a footwear system comprising a footwear body having a sole disposed on a bottom of the footwear body, a plurality of apertures disposed on a surface opposite the sole, one or more straps joined to a toe portion of the footwear body and extending from the toe portion rearward toward a heel portion of the footwear body. The footwear system can also include one or more removable insoles, each insole having a plurality of protruding members that extend from a bottom of the insole downward toward the apertures when the insole is installed in the footwear body. The plurality of protruding members correspond to the plurality of apertures and each protruding member has a first perimeter defined by an outer edge of an interface where each protruding member is joined to the bottom of the insole, and a second perimeter defined by an outer edge of a distal end of each protruding member. In some

implementations, the first perimeter is smaller than the second perimeter, and each of the apertures is configured to receive and engage a corresponding protrusion through interference fit. [0013] In some implementations, the plurality of removable insoles includes a first insole having a toe ridge, an arch support and a heel cup.

[0016] The plurality of apertures can include a first aperture and a second aperture, wherein the plurality of protruding members include a first protruding member and a second protruding member, wherein the first aperture corresponds to the first protruding member and the second aperture corresponds to the second protruding member, and wherein the first aperture is disposed in an area adjacent a front portion of the arch support and toe support section, and the second aperture is disposed in an area adjacent to the heel cup and a rear portion of the arch support. [0017] Some implementations can include an insole comprising an insole body portion, and a plurality of receptacles, wherein each receptacle is configured to receive and retain a pod, and wherein the plurality of receptacles includes one or more groups of receptacles arranged to retain a plurality of pods in positions to apply pressure on corresponding areas of a foot of a wearer. One or more of the plurality of receptacles can include a receptacle that has a first opening on a top surface of the insole body portion, a second opening on a bottom surface of the insole body portion, and a hollow section connecting the first opening and the second opening, and wherein the first opening is smaller than the second opening.

[0018] In some implementations, the insole can further comprise one or more pods, each pod having a first member and a second member, wherein the first member is configured to be positioned on the top surface of the insole body and includes a receptacle, and wherein the second member is configured to be positioned on the bottom surface of the insole body portion and wherein the second member includes a protrusion that is configured to extend upward from the second opening through the hollow section and engage the receptacle of the first member of the pod.

[0019] One or more of the plurality of receptacles can include a receptacle that has a first opening on a top surface of the insole body portion and a hole extending partially into the insole body portion, and wherein the hole is configured to retain a protrusion from a bottom of a pod. In some implementations, the insole can further comprise one or more pods, each pod having an upper surface configured to apply pressure to a foot of a wearer when the insole in placed into a shoe worn by the wearer, and a protrusion extending from a bottom of the pod, wherein the protrusion is configured to engage the hole of one of the receptacles in the insole body portion.

DETAILED DESCRIPTION

[0044] It will be appreciated that while the various example implementations may be described in terms of an insole and/or footwear, the insoles can be integrated with footwear and the insoles of the footwear examples could be made as standalone insoles that can be inserted into various types of shoes.

[0045] The plantar fascia is a tough layer of connective tissue that supports the arch and runs from the heel of the foot to the ball of the foot. Some implementations of the disclosed insoles and footwear can include weight bearing, solid pods (e.g., round protrusions) embedded within the insoles and footwear to create resistance and pressure while standing or walking. The pressure results in trigger point therapy and, for plantar fasciitis benefits, the focused pressure from the pods can help break up the soft connective tissue in the foot, which can help promote blood flow to the area, helping to aid, restore and rebuild the fascia in the foot. The embedded pods can be arranged and configured in the insoles and footwear to trigger areas where plantar fasciitis may be most prevalent. The embedded pods can vary in size, shape, diameter, height and composition, depending on placement and configuration as well as depth and material of footpad. Insoles according to the disclosed subject matter can be inserted into other footwear of a user's choice and can be used as frequently as needed. In some

implementations, insoles and footwear can include weight bearing, spherical embedded pods (e.g., having diameters of about 10mm, 12mm, or 14 mm, or other suitable dimensions) that apply pressure on trigger points as a user walks or stands. The insoles and footwear with pods can help stimulate areas associated with problematic foot issues such as plantar fasciitis. Because the spherical (e.g., marble like) or semi- spherical pods can be embedded in and through the insoles and footwear to provide resistance to maintain the trigger points as well as breaking through fascia creating blood flow to aid in restoring the fascia in the foot. [0046] Some implementations include insoles and footwear having a variety of useful properties. The insoles and footwear can provide particular therapeutic benefits to specific areas of the foot. This may be accomplished through the specific combination of multiple pod components that function together to modulate localized areas of foot pressure. Moreover, this combination of components can provide insoles and footwear that are easily customizable by the user to fit not only the specific needs of the user but also the changing needs of the user.

[0047] Accordingly, in one aspect, some implementations can include a removable insole configured for placement in a shoe between the shoe sole and the foot of a user, when the shoe is worn.

[0048] The insoles and footwear can be used in conjunction with an existing shoe insole or even in addition to another shoe insert. In some implementations, the insoles can be used to replace an existing shoe insole or an existing shoe insert. In some

implementations, the insoles may work particularly well when the insoles are the only insert present to modulate pressure between the foot of the user and the permanent shoe sole (e.g., the midsole or a non-removable insole). Additionally, some implementations may be integrated directly into a shoe or footwear product, such as a conventional closed toe shoe, a sandal or a flip-flop.

[0049] The insoles and footwear may comprise of a combination of materials. For example, the insoles and footwear may include a first material that is at least partially covered or enclosed by a second material. In other embodiments, the insoles and footwear may comprise multiple layers as well as a single layer. The insoles and footwear may comprise a gel material and a covering material that completely surrounds and encloses the gel material. In some embodiments, the covering material can be a thermoplastic polyurethane (TPU) material. For example, the insoles and footwear may include a gel that is comprised of a urethane gel coated with a thin film, such as a TPU film, silicone film, or other thermoplastic film. Some implementations can be made fully or partially from an ethylene vinyl acetate (EVA) based chemical composite.

[0050] For example, the gel material could be partially surrounded by a covering material such that different portions of the insoles and footwear interact differently with the shoe. In this instance, the covered portions of the insoles and footwear can resist adhering to other surrounding materials due to surface interactions such as by minimizing surface tension or friction.

[0051] In some implementations, the pods, insoles and/or footwear may be instrumented with force sensors (or other sensors) and associated electronics (e.g., power source (battery, kinetic power generator, etc.), microcontroller, flash memory, wired or wireless data communication interface, etc.) to measure forces in one or more locations to help measure the efficacy of the treatment provided by the insoles and footwear, and store data corresponding to the measured forces or other sensed parameters (e.g., number of steps, speed of steps, impact of steps, etc.).

[0052] The dimensions of the insoles and footwear may vary depending upon the shape of the pad, the location of the pad relative to other pads, the location of the pad relative to an anatomical part of the foot, and the overall size of the insoles and footwear.

[0053] In some implementations, the insoles and footwear can include multiple layers and can be formed using, for example, a single material injection or a "double shot" molding process. In this regard, a first layer or skin of a moderator sheet (e.g., TPU material or the like) may be placed into a mold and a first shot of polymeric material (e.g., thermoset or thermoplastic polyurethane or similar materials of various durometers) may be placed on the skin and the mold closed to cure the first shot and form a first layer of polymeric material on the skin. The mold may then be opened and a second shot of polymeric material (e.g., thermoset or thermoplastic urethane) may be placed on the skin and the first layer of polymeric material. The mold is then closed to cure the second shot and form the second layer of polymeric material. The first and second layers formed on the skin may have different material properties from one another, such as different stiffness and/or elasticity. For example, the first layer formed on the skin may be stiffer than the second layer formed on the skin. Foamed materials tend to resist full

deformation of the layer.

[0054] The insoles and footwear can include formed pressure pods, especially in combination with the series of pods. These pods may be of various geometric

configurations from simple semi spheres to semi oblique spheroids, and may have transfer functions describing natural curvature, such as the Fibonacci spiral segments. As well, these pods may be either active or static wherein the active members may be spring loaded with elements that compress and then expand swiftly to cause a massaging element. Additionally, the insoles and footwear may contain radio frequency emitting elements, heat, infrared heat, vibration, cooling elements, plant-derived essential oils and/or dried plant products applied to or constructed within the insoles and footwear, flip- flop, footwear and or footwear components to deliver the comfort, disinfectant and/or therapeutic benefits of aromatherapy through direct contact with the wearer's feet with the volatile components of the plant derived oils and/or plant products. For instance, a flip- flop or sandal may have an aromatherapy component built in which distributes out of perforations strategically placed on the flip-flop. The flip flop may also have larger perforations, aesthetically pleasing to allow pass-through of sand and water to make it easier to walk.

[0055] The insoles and footwear with pods may contain a rivet, fastening, crimping or snap system and the like. This system may also apply to a flip-flop, permanent foot bed, sole and the like.

[0056] Some implementations provide an ability to distribute pressures on the foot by both applying beneficial pressure and simultaneously modulating that pressure. This provides a unique system for providing foot therapies through the use of insoles and footwear.

[0057] The insoles and footwear may be formed of materials and/or configured to reduce noise during use. In this regard, the insoles and footwear may be texturized to reduce if not eliminate noises while a user is wearing the insert. For example, the insoles and footwear may be texturized in specific areas in order to reduce frictional noise or squeaking between the insert and the interior of the insoles and footwear. The insoles and footwear may be texturized using a micro finish (e.g., ridges and indentations) or mat finish. For instance, portions of the insoles that are expected to interface with the shoe could be texturized, such as the sidewall surfaces of the insole (i.e., those between the major opposing surfaces of the insole), which could include those surfaces in the region of the arch, heel cup, and/or other outer edges of the insole. The insole could be texturized using other techniques such as by adding an additional layer of fabric or other material or adding a lubricant such as silicone. [0058] Smaller pods may provide more intense pressure while the larger pods may provide a gentler pressure. Natural shape and dimensions allow the user to apply weight - bearing pressure for as long as required to achieve relief and/or restorative effects. The design and accurately placed therapy pods create weight bearing pressure to the appropriate points in a user's foot to accomplish the required or desired therapy such as: trigger point therapy, myofascia release, reflexology, Shiatsu, Thai massage and a host of other modalities to promote healing for common complaints such as plantar fasciitis, heel pain, foot arch pain, generalized complaints that may correspond to certain reflex points in the feet.

[0059] Some implementations can include insoles and footwear with embedded, elevated pods to stimulate and sustain trigger points while helping to tenderize and break up scar tissue by penetrating deep into the fascia to restore or relieve foot pain, plantar fasciitis, metatarsal pain, heel spurs, neuromas, pinched nerves and aching feet.

[0060] Some implementations can include conventional footwear features associated with sandals and other common types of footwear. The insoles and footwear can include a pair (e.g., left and right footwear) with conventional features including soles and latching straps for securing a shoe to a user's foot. Yet still another object of the present invention is to provide improved traction means on slippery surfaces via a tread surface along a bottom surface of the footwear.

[0061] The pods are preferably positioned in the insoles and footwear to correspond to anatomical portions of the foot where pressure points are likely to occur or where foot diseases or conditions related to pressure may occur. In some embodiments, at least a portion of the pods can be positioned in an area of the footpad insert/insole corresponding to plantar fasciitis, trigger point therapy or many other modalities used for common foot complaints.

[0062] Some implementations can include a footpad insert/insole that can provide therapeutic benefit to a user by modulating pressure applied to the foot of a user. The insoles and footwear make use of a combination of removable foot inserts to beneficially alter pressure in the localized area of the feet to activate reflex or trigger points that correspond to the anatomy of the body or to the foot itself.

[0063] The insoles and footwear may further comprise a cushioning layer. Such layer may have a variety of sizes covering all or a part of the overall area of the insert. In particular, the cushioning layer may be positioned to separate at least a portion of the pods from the foot of the user. The cushioning layer may be made of a variety of materials, such as polyurethane foam as well s a mixture of materials to attain the desired durometers (or hardness).

[0064] The beneficial pressure abilities of the insoles and footwear can particularly be related to the pressure of the pods and the properties thereof that allow for distribution of pressure between the foot user and the pods, which can comprise a thermoplastic polyurethane material and the like or any other moldable composition available.

[0065] Listed below are three costly restorative therapy treatments recommended for plantar fasciitis. These treatments may offer the same result as the disclosed insoles and footwear by helping increase blood flow to the injured area, which can help naturally restore the soft tissue. [0066] Amniotic cell treatment delivered through a needle can cost up to $1000 per treatment it is believed that the umbilical cord matrix increases the blood flow response by delivering healthy cells to the area. Blood flow naturally restores the soft tissue.

[0067] Shockwave therapy gradually increased the blood flow supply to area by tenderizing the fascia and breaking up scar tissue.

[0068] Radio frequency penetrates the deepest causing the most aggressive blood flow to the area and may be the only conventional restorative treatment that penetrates deep into the fascia layer. This really targets the area and helps generate healthy cells for soft tissue to regenerate itself, essentially sending a red flag up for the body to come heal itself.

[0069] The design of the disclosed pods can trigger a response in a patient's body similar to the response from PRP (Platelet Rich Plasma) therapy. PRP therapy uses a process in which blood of a patient is extracted, spun it and the blood cells are separated from the plasma. The plasma carries a concentrated amount of vital nutrients that is thought to accelerate the healing and regeneration of soft tissue (fascia).

[0070] In a professional setting, plasma is extracted and delivered via injection to the plantar fascia. PRP injections can cost about $2500 each, and may not be covered under insurance. Further, PRP therapy is invasive and aggressive.

[0071] The disclosed pod insoles and footwear therapy creates surface resistance to tenderize the fascia and break up fascia adhesions to signal the body to send blood flow to the injured area. This approach using the disclosed insoles and footwear is natural and very comparable to PRP in that pod therapy using disclosed insoles and footwear can promote sustainable, consistent blood flow to the injured fascia. While an injection may work within a few days, a patient must account for down time associated with PRP. The disclosed insoles and footwear may also take extended days to help promote a similar amount of nutrients as PRP without the down time of PRP. Therapy using insoles and footwear having pods as disclosed herein can offer an advantage of a non-invasive therapy for literally a fraction of the price of PRP (and the other therapies mentioned above).

[0072] The removable insoles and footwear provide a single solution, designed for restorative therapy, allowing a user to treat and rehabilitate herself/himself. Some implementations if the insoles and footwear can both tenderize the scar tissue and penetrate deep down to the fascia layer to help promote blood flow to help restore the fascia back to a healthy, mobile state. The weight bearing pods penetrate deep into the fascia for a restorative experience combined with reflexology and trigger point therapy.

[0073] Various configurations, placement, height, width, material, durometer, overlays, shape, hollowing, solid or semi-solid composition of pods reflects the particular functionality of the insoles and footwear, for instance, different configurations may impact various common conditions such as plantar fasciitis or by stimulating the appropriate reflex zones or pressure points of the foot may impact sleep problems by such stimulation the following points: pineal - secretes melatonin and controls sleep, head/brain - induces clarity and positive thinking, thyroid - normalizes melatonin, pituitary- master gland-balances hormones, neck/shoulder -releases tension, chest/lung- calms breathing.

[0074] Another configuration example can be a weight loss footpad insert/insole with the pods appropriately placed that stimulate the following points: stomach/pancreas- stimulation of these points allows the body to absorb more nutrients, spleen- reduces hunger, gallbladder- stores bile, bile emulsifies fats, endocrine glands-promotes hormone balance and regulates appetite, diaphragm line- all sleep and relaxation. There are many configurations to combat the most common complaints and or customized configuration to address a particular condition or multiple conditions in one footpad. There can also be a very standard configuration which may correspond to all the major reflex points in the foot to impact an overall, generalized state of well being.

[0075] The pods on the disclosed insoles and footwear can help to loosen up the fascia (connective tissue), increase blood flow, promote restoration of soft tissue, massage the muscles, mobilize the bones, increase lymphatic circulation and as a bonus it increases foot flexibility.

[0076] Reflexology theory corresponds to a particular area upon one's foot linked to various points and organs therein the body such as kidneys, liver, skeletal joints, and the like, as defined thereby conventional reflexology diagrams. Thus, as a user walks using the insoles and footwear, they may experience massaging, relaxation, and an overall body wellness.

[0077] According to reflexology theory, the application of direct pressure to the reflex- zones or pressure points in the feet, promotes a healing response (or reflex) in the corresponding anatomy. According to reflexology theory, every part of the anatomy is connected to the foot and is represented by a reflex-zone located on a specific part of the foot. By accurately applying pressure to these specific areas, the relevant part of the foot and/or body is stimulated or affected.

[0078] The concept of reflexology involves the relief of stress in various parts of the human body by vigorous stimulation of specific areas located on the sole of the foot. For example, the area of the big toe is associated with relieving sinus problems. The area at the ball of the foot is associated with stomach disorders. Each specific area of the sole of the foot is connected to a different organ of the body according to those who practice reflexology. Conventional footpad inserts do not give an adequately deep tissue massage to all the specific reflexology points of the sole of a user's foot. The disclosed insoles and footwear can provide relief to other body parts through the concept of reflexology.

[0079] The left foot corresponds to the left side of the body and all organs, valves, etc. found there. The right foot corresponds to the right side of the body and all organs found there. For example, the liver is on the right side of the body, and therefore the

corresponding reflex area is on the right foot. The pods are positioned to correspond to areas of the foot that are linked to various points and organs in the human body such as kidneys, liver, skeletal joints, and the like. Thus, as the user walks, they experience a trigger point massaging effect resulting in increased relaxation, and overall body wellness. This design may be incorporated into various styles of footwear including sandals, shoes, boots, and the like.

[0080] The footpad can be configured in many ways depending on the therapy being used and how aggressively it will break through fascia. Smaller pods provide different pressure than larger pods. A combination of different sizes will also result in different pressure and therapy. Someone who walks under 5 miles a day may choose insoles and footwear with a less aggressive configuration and maximum pressure on trigger points and fascia breakup. Weight of the user can also be a factor. Someone who walks more than 5 miles a day may consider insoles and footwear with a less aggressive configuration since pods apply continuous pressure on trigger points as well as fascia ruptures. There can be variations of the insole material and embedded pod configuration to create insoles and footwear for broader foot therapies such as Shiatsu or reflexology. The footpad can also be customized for isolated issues such as someone who is diabetic or has sensitive feet. The embedded pods can be any size, shape or composition and can have any placement configuration for a multitude of health and or foot benefits. In some implementations, the insoles can include any material and or combination of pods with a variety of arch supports as well as an extended food pad around lower ankle, creating support with or without pods in the lower ankle and upper heel. Strategic pod

configurations can result in trigger point therapy in foot to relieve a host of issues such as heel spurs, circulation, and anything else related to foot health or the repair and rebuild of fascia. The pods break through fascia in the foot, increasing blood flow to the area, creating an environment for repairing and rebuilding the fascia. Insoles and footwear can also include metals or magnets for other therapeutic values. The pods help relax tense muscles while applying pain relieving trigger point therapy to points along the foot, to promote blood flow, energy levels and maximize healing so that a user's feet can perform better.

[0081] The human foot contains 26 bones, 19 muscles and more than 100 ligaments. The foot also contains hundreds of nerves and blood vessels. According to the Chinese medicine, there are more than 60 reflex points, which correspond directly with other pails of the body. With the proper configurations and placement of embedded pods, most, if not all of these reflex points can be stimulated while walking or standing. The insole concept can also apply to a flat variation on a foam flip flop with pods embedded into flip flop. This can change the way flip flops are used, where the flip flops provide therapeutic properties and yet still remain stylish. The insoles and footwear can have a variation with pods embedded directly into the sole of the footwear, as a permanent feature, providing the same design and benefit as the insole.

[0082] The term pods refers to a footpad insert/insole, flip flop, foot bed, sole or permanent structure of any footwear that consists of a protrusion or knob embedded or not embedded at a full depth, partial depth or sitting flat on surface. The pods can be elevated above footpad/insole surface to allow for both resistance and continuous stimulation. While the pods stimulate pressure points, the pods can also help tenderize and or break up fascia in the foot area, where various forms of fasciitis are relevant. Blood flow will be established by penetrating the layer between the skin and muscle. When the fascia in foot is manipulated it helps to create flexibility, allowing foot to become pliable. The pods will break through soft tissue and restore and strengthen fascia in the foot.

[0083] Fascia restriction may result in pain or restriction of movement as well as weaker muscles, decreased circulation of fluids leading to high blood pressure, lower immune function and hormone imbalance, affecting our ability to withstand stress and perform daily activities. The disclosed insoles and footwear having pods, hydrates the soft tissue of the fascia by flooding it with oxygenated blood and fluid.

[0084] As mentioned above, the human foot contains 26 bones, 19 muscles and more than 100 ligaments. The foot also contains hundreds of nerves and blood vessels.

According to the Chinese medicine, there are more than 60 reflex points, which correspond directly with other parts of the body. With the proper configurations and placement of embedded pods, most, if not all of these reflex points can be stimulated while walking or standing. The insoles and footwear concept can also apply to a flat variation on a conventional foam flip flop with pods embedded into the flip-flop. This can change the way flip flops are used and the flip flops can still remain stylish. The flip- flop can be made of any material to achieve the outcome of desired results. The insoles and footwear can have a variation with pods embedded directly into the sole of the footwear, as a permanent feature, providing the same design and benefit as the footpad insert/insole, flip-flop or foot bed. In addition, the foot pad insert/insole may contain proper arch design to provide foot alignment and balances to impact areas for shock absorption, reduced foot fatigue, and potential of increased footwear life. Some foot pad insert/insole elements may also consist of a foam top piece that absorbs and wicks away moisture, cork and EVA construction to provide flexibility and absorb impact shock, an anti-slip bottom coat increases durability and protects for longevity of foot bed life, raised side flanges to aid in controlling foot movement and stability, a deep heel cup to provide natural cushioning, shock absorption, and protects the heel bone for foot pain relief.

[0085] The inventive footpad insert/insole, flip-flop or permanent integration directly into the shoe product with pods can also consist of any material, combination of materials, compositions and the like until desired comfort and effectiveness has been satisfied. An example may be the ultralight, ultraflexible Ethylene- Vinyl Acetate (EVA) material that keeps the user light on their feet throughout your day. EVA's nano- molecular structure also provides an effect of smoothness and gives a consistently comfortable fit. Another example may be foam, memory foam, carbon fiber memory foam and the like. [0086] Footpad inserts/insoles can come in standardized sizes, which allow for customization. A user may need to trim them to fit into the shoe or footwear of choice.

[0087] The plantar fasciitis insoles and footwear with pods standard size allow for proper therapy because the plantar fascia runs the length of the foot bed from heel to toe.

[0088] To customize insoles and footwear, trim the footpad inserts/insoles using a pair of scissors sharp enough to cut through dense cardboard. Cut the excess material around the toes and instep areas, as clipping these areas is less likely to disfigure the shape of the footpad insert/insole. Once the footpad insert/insoles are trimmed, they should fit properly into your shoes. You can also trace around the original footpad insert/insole of the footwear you will be replacing to get an outline to cut along, although this method may make the new footpad insert/insole slightly bigger than necessary, you can revert to a foot outline for a more custom fit.
