Description

Technical Field

[0001] This disclosure describes aspects generally related to footwear. In one aspect, the sole of the foot includes an insert positioned on the medial side of the arch area of ​​the foot. Background Technology

[0002] The background description provided herein is for the purpose of presenting the context of this disclosure in its entirety. To the extent that the work described in this background section is intended, the work of the currently designated inventors and aspects of the description that may not conform to the prior art at the time of submission are neither expressly nor implicitly acknowledged as prior art relative to this disclosure.

[0003] Recovery shoes, also known as post-workout or post-exercise shoes, are designed to provide comfort and support to individuals after physical activity. Following strenuous physical activity, the venous system in the feet can be under increased pressure. Furthermore, strenuous activity can lead to swelling of the feet and ankles, which can further impair the function of the venous system. Recovery shoes designed with cushioning and arch support to reduce pressure on the soles of the feet can help reduce foot fatigue and discomfort, potentially promoting better venous circulation in the lower limbs. When the muscles in the foot relax, they support the natural function of the venous pump in the foot, which helps blood return to the heart. Summary of the Invention

[0004] The invention includes a recovery shoe and a method of manufacturing the recovery shoe. In some examples, the recovery shoe includes an insert in the sole of the shoe to improve venous circulation in the lower limbs of a person.

[0005] According to one aspect of this disclosure, a shoe is provided. The shoe includes a sole. The sole includes a base and an insert. The base includes a toe portion, a heel portion, and an arch portion disposed between the toe portion and the heel portion. The insert is disposed in the arch portion of the base and further projects from a first surface of the base into the arch portion. The lowest position of the insert is the lowest point of the first surface of the sole relative to the ground. The shoe includes an upper above the sole.

[0039] Figure 11 A flowchart outlining some aspects of the manufacturing process according to this disclosure is shown. Detailed Implementation

[0040] According to previous reports on recovery shoes, most recreational runners stride 150-170 steps per minute. Therefore, having recovery shoes can help relax and initiate the repair process, such as recovering from muscle fiber tears, foot swelling, or collapsed arches after a race.

[0041] Running activities can be characterized based on running pace. Running pace is defined as steps per minute (spm). Most recreational runners have a running pace of 150 to 170 spm. Recovery is one of the key phases of running. Having recovery shoes can help relax and initiate the repair process, such as recovering from muscle fiber tears, foot swelling, or arch collapse after a race.

[0042] During long-distance running, the repeated load causes the arch height to gradually decrease, and it also decreases momentarily at each standing phase. Among volunteers aged 20-53 who registered for a half marathon, their foot posture became more pronated after the race.

[0043] If recovery from exercise takes time, the risk of injury may increase because changes in foot posture and / or foot parameters can alter running mechanics.

[0044] On the one hand, arch support insoles can significantly reduce peak VO2 during uphill and downhill walking. Peak VO2 is a measure of the maximum amount of oxygen the body can utilize during strenuous exercise. Arch support insoles can reduce fatigue of the rectus femoris muscle during downhill walking. The firmness of the insole not only increases physical sensory input but also increases fatigue of the lower limb muscles, such as the rectus femoris muscle fatigue in people with flat feet when walking uphill.

[0045] On one hand, requirements for recovery shoes may include arch support, cushioning, a wide toe box, breathability, lightweight design, and a swing sole design. In the example of a swing sole design, the sole facilitates a natural rolling motion during walking or running. This natural rolling motion can be characterized by a curved or upward-curving shape, such as at the forefoot, which promotes a smoother transition from heel strike to toe lift.

[0046] The plantar venous plexus is located in the sole of the foot, below the arch area. It acts as a built-in pump for blood return. Each time the foot interacts with the ground, the plantar venous plexus flattens, stretches, and compresses, pumping blood back to the heart. By creating a midsole geometry in the shoe, which stimulates blood pumping when weight is applied, it aids in recovery from muscle trauma caused by the exertion of exercise.

[0047] The plantar venous plexus comprises several large-diameter veins that cross the arch of the foot. Compression of the plantar venous plexus, which can occur during walking, can significantly increase flow into the popliteal vein via the posterior tibial venous system.

[0048] In one aspect of this disclosure, a testing program for pulse (recovery) shoes may include the following steps: Step 1, participants wear control shoes (e.g., running shoes) and undergo an exercise stress test. Step 2, the exercise stress test continues until the participant engages in full-force exercise based on VO2 and RPE (Perceived Rate of Exertion) monitoring. In this example, VO2 is a physiological measurement indicating the maximum amount of oxygen available to the body during strenuous exercise. RPE is a subjective measurement used to quantify the intensity of physical activity based on how a person feels during exercise. RPE can be a valuable tool for monitoring a person's exercise intensity, especially when a heart rate monitor or other objective measurements are unavailable. Step 3, after reaching full completion, participants change into recovery shoes and relax. Step 4, fatigue recovery is observed by lactate analysis before and after the exercise stress test. In this example, lactate levels are monitored at 5-minute intervals after the test to observe fatigue recovery.

[0049] The plantar venous pump comprises multiple veins located deep between the muscles of the foot and compressed during weight-bearing activities. The term "plantar venous pump" refers to the mechanism by which veins in the sole of the foot help blood return to the heart. The plantar venous pump is part of the overall venous system and plays a crucial role in maintaining proper blood circulation. On one hand, the venous pump in the foot is the first step in the venous return of blood during walking, just before the pump in the calf. The plantar venous pump is important in the legs and feet because blood flow in these areas faces the challenge of overcoming gravity to return to the heart.

[0050] Foot reflexology is a therapeutic practice involving applying pressure to specific points on the feet. Foot reflexology can help stimulate blood flow in the feet and calves and improve blood circulation. Improved circulation can be beneficial for individuals with venous problems, as it reduces swelling and discomfort associated with poor blood flow. By promoting lymphatic drainage and blood circulation, foot reflexology can aid fluid movement and reduce edema. Foot reflexology can help relieve pain in the feet, especially if a person has been working their feet for a long time or suffers from conditions such as plantar fasciitis. The pressure applied during foot reflexology can help reduce muscle tension and pain. Increased energy levels and vitality are reported after foot reflexology, likely due to improved circulation and relaxation of tense muscles.

[0051] The plantar venous arch is a network of veins located on the sole of the foot (e.g., the surface of the foot). This network of blood vessels is responsible for draining blood from the tissues of the foot and returning it to the larger veins in the lower limbs, ultimately returning to the heart. At rest, the plantar venous pump may not be active, therefore the plantar venous arch is necessary to provide a specific continuity of venous return.

[0052] This disclosure provides a recovery shoe. The recovery shoe (or shoe) includes an insert (or core) disposed in the arch portion of the sole of the shoe. The lowest point of the insert is the lowest point of a first surface of the sole relative to the ground. The insert is positioned on the medial side of the shoe and corresponds to a large vein (e.g., a large vein of the plantar venous plexus) in the arch region of the user's foot. The insert is configured to perform foot reflexology. For example, when the shoe is worn and the sole is pressed by the user, the insert can provide pressure to the user's arch (e.g., the plantar venous arch). The pressure can stimulate the veins in the arch region of the foot through the insert and promote blood flow via the plantar venous pump. The promoted blood flow can help aid recovery from muscle trauma caused by exertion during exercise and reduce fatigue in the lower limb muscles (e.g., the rectus femoris) of users with flat feet during uphill walking.

[0053] Figure 1A An exemplary recovery shoe (or footwear) 100 is shown. (As...) Figure 1AAs shown, shoe 100 includes a sole 102 and an upper 104 above the sole 102. Sole 102 includes a base 106 and an insert 108. Base 106 includes a toe portion 110, a heel portion 112, and an arch portion 114 disposed between the toe portion 110 and the heel portion 112. Insert 108 is disposed in the arch portion 114 of base 106 and further protrudes from a first surface 106A of base 106 into the arch portion 114. The lowest point 116 of the first surface 108A of insert 108 is lower than the first surface 106A of base 106 relative to a surface in contact with the shoe (e.g., the ground). Upper 104 includes a toe portion 118, a rear portion 120, and a tongue 122 disposed between the toe portion 118 and the rear portion 120. Insert 108 is configured to provide pressure to the arch area of ​​the user's foot (not shown) when the shoe 100 is worn and the sole is pressed by the user.

[0054] Still referencing Figure 1A The midsole (or arch portion) 114 of shoe 100 includes a core (also called an insert) 108. The lowest point (or location) 116 of insert 108 is located on the medial side of the arch region and is the lowest point of shoe 100 relative to the ground. In other words, when shoe 100 is placed on a table, insert 108 protrudes below any other surface of shoe 100 (e.g., 106A). This protruding geometry of shoe 100 results in pressure being applied to a group of veins located deep beneath the arch region of the user's foot. When the user walks or engages in physical activity, insert 108 stimulates this group of veins based on a repetitive base (or load). For example, the user's foot may press against the ground during walking. Pressure can be returned to the arch region of the foot via insert 108. The pressure returning from the ground via insert 108 stimulates the veins in the arch region of the foot and promotes blood flow via the plantar venous pump.

[0055] On one hand, the base 106 and the insert 108 are made of different materials. On the other hand, the base 106 and the insert 108 are made of the same material.

[0056] On one hand, the density of insert 108 is different from the density of base 106. On the other hand, the density of insert 108 is greater than the density of base 106.

[0057] On one hand, insert 108 and base 106 are a single piece, wherein insert 108 is attached to base 106 by inserting it into base 106 from a first surface 106A of base 106.

[0058] On the one hand, insert 108 and base 106 are single pieces formed together based on a mold.

[0059] Figure 1BThe bottom view of shoe 100 is shown. (As shown) Figure 1B As shown, the base 106 includes one or more recessed regions 124 concentrically arranged around the insert 108. The insert 108 is closer to the inner side 114A of the arch portion 114 than the outer side 114B of the arch portion 114.

[0060] Figure 1C Another bottom view of shoe 100 is shown. (See image) Figure 1C As shown, the lowest position 116 of the insert 108 is the lowest point of the first surface 102A of the sole 102. The first surface 102A of the sole 102 is the contact surface with the ground. The first surface 102A of the sole 102 may include the first surface 108A of the insert 108 and the first surface 106A of the base 106. The insert 108 is positioned on the inner side 114A of the arch portion 114 of the base 106 and corresponds to the large vein (not shown) in the arch region of the foot. In one aspect, the first surface 108A of the insert 108 (corresponding to the lowest position 116) is a curved surface protruding from the first surface 106A of the base 106 of the sole.

[0061] Figure 2 An enlarged view of the sole 102 is shown. (As shown) Figure 2 As shown, the base 106 includes one or more recessed regions 124. These recessed regions 124 are concentrically arranged around the insert 108. In one aspect, the recessed regions 124 are configured to help activate the insert 108 to stimulate veins in the arch region of the foot. In another aspect, the recessed regions 124 form cavities of relatively small thickness within the base 106, which in turn reduces the area of ​​the insert 108. Therefore, the recessed regions 124 isolate areas of the insert 108 and create fracture zones that allow for changes in the user's movement rate. In one aspect, the recessed regions 124 are formed by removing material from the base 106 within the recessed regions. In another aspect, the recessed regions 124 are produced based on a mold in which a pattern is provided to form the recessed regions.

[0062] Figure 3 The area of ​​foot 300 is shown. Foot 300 includes a weight-bearing area 302. Foot 300 also includes a manual compression area 304 for the plantar veins. The manual compression area 304 can be located in the arch region of foot 300. In one aspect of this disclosure, a core / insertion (e.g., 108) is included in the sole (e.g., 102) of a shoe (e.g., 100). The core (or insert) can stimulate the manual compression area 304 for the plantar veins, which can improve blood circulation via the plantar venous pump. Therefore, it promotes recovery after physical activity (e.g., running).

[0063] Figure 4 This is an inner side view of the sole 102 according to some aspects of this disclosure. For example... Figure 4 As shown, the sole 102 has a first surface 102A and a second surface 102B opposite to the first surface 102A. The first surface 102A is a contact surface with a surface (such as the ground). The second surface 102B is a contact surface with the foot (such as foot 300). In one aspect, the lowest position 116 of the insert 108 is the lowest point of the first surface 102A of the sole 102. The second surface 102B of the sole 102 protrudes from the arch portion 114 of the base 106 toward the arch region of the foot (not shown).

[0064] Figure 5 This is a bottom view of the sole 102 according to some aspects of this disclosure. For example... Figure 5 As shown, one or more recessed areas 124 are concentrically arranged around the insert 108. In one aspect, the recessed areas 124 are configured to help activate the insert 108 to stimulate veins in the arch region of the foot.

[0065] Figure 6 This is an external view of the sole 102 according to some aspects of this disclosure. For example... Figure 6 As shown, insert 108 has an elliptical or rounded triangular cross-sectional shape obtained from a vertical plane along the direction from the toe portion 110 to the heel portion 112 of base 106. Insert 108 extends from a first surface 106A of base 106 into the arch portion 114 of base 106. Second surface 108B of insert 108 contacts the first surface 106A of base 106. First surface 108A of insert 108 is a curved surface protruding from the first surface 106A of base 106.

[0066] Figure 7 It is along the direction from the toe portion of the base 106 to the heel portion (such as... Figure 5 The cross-sectional view of the recovery shoe 100 obtained from the vertical plane (direction A1-A2 in the figure). Figure 7 As shown, shoe 100 includes a sole 102 and an upper 104. The lowest position (or point) 116 of insert 108 is the lowest point of the first surface 102A of sole 102. Insert 108 corresponds to the arch region of the foot. Insert 108 has an elliptical cross-sectional shape or a rounded triangular cross-sectional shape.

[0067] Figure 8 This is a top view of the recovery shoe 100 according to some aspects of this disclosure. In one aspect, a 3D model of the human foot (such as an anatomical last) is applied to the design of the upper 104 of the shoe 100 to improve fit and comfort. Figure 8 In the example, the FLL-2730-1 anatomical last is applied to design shoe 100.

[0068] Figure 9Various cross-sectional views 901-904 are shown from the inner to the outer side of the recovery shoe 100 according to some aspects of this disclosure. For example... Figure 9 As shown, cross-sectional view 901 along Figure 5 The directions B1-B2 in the diagram are obtained from the vertical plane. Section 902 is along... Figure 5 The directions C1-C2 are obtained from the vertical plane. Section 903 is along... Figure 5 The directions D1-D2 are obtained from the vertical plane. Section 904 is along... Figure 5 The directions E1-E2 are obtained from the vertical plane.

[0069] Figure 10A A bottom view of the recovery shoe 100 according to some aspects of this disclosure is shown. Figure 10B It shows in Figure 10A A cross-sectional view of the recovery shoe 100 obtained from the vertical plane along the direction D1-D2. (See figure) Figure 10A As shown, the arch portion 114 of the base 106 may include a center position 126, and the insert 108 may include a center position 128. The center position 126 of the arch portion 114 may be the geometric center, pressure center, or design center of the sole 102. Therefore, the center position 126 may indicate the center of the sole 102. In the example, the geometric center is calculated using the average of the x (or horizontal) and y (or vertical) coordinates of all points on the sole. In the example, the pressure center indicates the point where most of the pressure is applied when the shoe is worn. In the example, the design center indicates the point that the shoe designer intended to be the center, typically based on aesthetic or functional considerations. In the example, the center position 126 may have the same distance to the inner side 100A and the outer side 100B of the shoe 100. The center position 128 of the insert 108 is offset from the center position 126 of the arch portion 114 of the base 106 by a distance... L. Therefore, the center position 128 of insert 108 is closer to the inner side of the shoe than the outer side of the shoe. In the example, the distance is... L is in the range of 2 mm to 8 mm.

[0070] Therefore, the lowest position (or point) 116 of the core (or insert) 108, serving as the pressure point, can be positioned closer to the medial side of the foot for manual compression of the plantar vein area. The transverse arch of the human foot is higher on the medial side and has a gradually decreasing structure. In the example, for the plantar vein pump system, the apex (or top) of the core (or insert) can be located approximately 5 mm to 7 mm on the medial side. In the example, the center of the core (or insert) (e.g., 128) can be moved 5 mm to 7 mm towards the medial side from the center (e.g., 126) of the shoe's sole interlayer.

[0071] On one hand, the insert can be stiffer than the rest of the sole, allowing it to push force back to the arch area of ​​the foot. For example, the insert can have a higher density than the rest of the sole. On the other hand, the insert and the rest of the sole can have the same density. As described above, the insert protrudes from the rest of the sole (e.g., the base). When the foot strikes the ground, the ground pushes upwards through the insert to the arch area of ​​the foot. The insert then stimulates the veins in the arch area. Therefore, with each step and each time a person steps on the insert, the insert pumps more blood through the plantar veins compared to a shoe without an insert. For example, more blood can be pumped through the insert protruding from the sole compared to an arch support from the shoe. In this example, the more the insert protrudes from the rest of the sole, the more blood can be pumped.

[0072] On the one hand, the insert can be made of any suitable material, as long as it is the lowest point (or area) of the shoe's sole. When body weight is applied to the insert, it can stimulate the arch area of ​​the foot through pressure.

[0073] On one hand, the inserts on the sole are separate from the rest of the sole. Therefore, the sole and the rest of the sole are two separate pieces. The inserts can be inserted into the sole and further bonded to the rest of the sole.

[0074] On the one hand, the chemical composition of the insert differs from that of other areas of the sole. On the other hand, the insert and other areas of the sole may have the same chemical composition.

[0075] On one hand, the insert and other areas of the sole have the same components. For example, the insert and other areas of the sole are manufactured together, such as based on the same mold.

[0076] On one hand, the insert in the sole is positioned at the arch region of the foot. To ensure the insert is located (or corresponds) to the arch region of the foot, mathematical equations are applied to different shoe sizes. According to these equations, for each shoe size, the insert is arranged at the arch region of the foot. Therefore, the anatomical placement of the insert in the shoe aligns with the plantar venous plexus, which includes a series of veins. Thus, inserts with rounded triangular or elliptical shapes correspond to (or contact) the largest venous cluster in the lower limbs of the body.

[0077] Figure 11 A flowchart outlining the process 1100 for forming a shoe according to one aspect of this disclosure is shown. The process begins at S1101 and proceeds to S1110.

[0078] In S1110, the base of the sole is formed based on the first mold, wherein the base includes a toe portion, a heel portion, and an arch portion disposed between the toe portion and the heel portion.

[0079] In S1120, an insert for the sole is formed. The insert is arranged in the arch portion of the base and further protrudes from the first surface of the base into the arch portion. The lowest position of the insert is the lowest point of the first surface of the sole that contacts the ground.

[0080] In S1130, an upper is formed above the sole, wherein the upper includes a toe portion, a rear portion, and a tongue disposed between the toe portion and the rear portion.

[0081] Then, the process proceeds to S1199 and terminates.

[0082] Process 1100 can be adjusted as appropriate. One or more steps in process 1100 can be modified and / or omitted. Additional steps(s) can be added. Any suitable implementation order can be used.

For example, references to at least one of A, B, or C; at least one of A, B, and C; at least one of A, B, and / or C; and at least one of A through C are intended to include only A, only B, only C, or any combination thereof. References to one of A or B and one of A and B are intended to include either A or B or (A and B). Where applicable, such as when the elements are not mutually exclusive, the use of “one of” does not exclude any combination of the listed elements.

[0084] While this disclosure has described several examples of aspects, there are variations, substitutions, and different alternative equivalents that fall within the scope of this disclosure. Therefore, it should be understood that those skilled in the art will be able to design numerous systems and methods that, although not expressly shown or described herein, embody the principles of this disclosure and are therefore within its spirit and scope.
