Definitions

• This invention relates to shoe soles and, more specifically, to an inner shoe sole that is structured to react to movement by the wear's foot.
• Shoe soles are well known in the prior art. Modern shoe soles include many layers, e.g., an outer sole, an middle sole and an inner sole. Typically, there is a rubber outer layer that is structured to contact and engage the ground. This layer has a bottom face that includes a tread or a plurality of protrusions. The rubber outer layer has an upper face that contacts an inner layer.
• the inner layer typically includes one or more layers of padding. The inner layer may be shaped, e.g., have an arch support. The inner layer, however, is not structured to react to movement occurring within the foot and be guided by the foot during walking.
• the human foot is a complex machine of bone linked by a matrix of ligaments and tendons. As a person walks, the foot performs complex actions to stabilize the body and move the body in the desired direction. For example, a runner's bare or naked foot structure naturally adjusts or conforms its shape to provide balance for the body on the soft beach to the inclined variables of the terrain.
• the internal structure moves its complex matrix and adjusts its shape to work in opposing planes in motion.
• the moving structure alters the shape of multiple arches. This changes multiple structural functions that suspend, lock, and lever toe extensions along transverse, sagittal and frontal planes. However, the ability of the structure to move along multiple planes is limited and altered by man- made footwear. Much of the natural movement is lost do to the opposing shoe structures.
• the present invention provides a sole assembly that includes a outer sole assembly and a reactive upper sole assembly.
• the reactive upper sole assembly is structured to react to movements by and within the wear's foot. These movements are translated by the reactive layer to movement between the reactive upper sole and the outer sole. That is, both the outer sole and the reactive upper sole have a plurality of contact or engagement points. These contact or engagement points may be: (1) two or more protrusions, (2) a protrusion and a void, or (3) two or more voids, soft areas, or areas of different resiliency. Depending on how the foot of a specific user moves, these engagement points are activated.
• the outer sole assembly reacting to and in response to the reactive upper sole assembly, is changed. That is, the upper and outer sole assembly, according to the present invention, facilitate a sole in which the foot guides the sole instead of the sole guiding the foot.
• the protrusions on the lower surface of the outer sole can be programmed or designed for gripping, braking and guidance. That is, by having the external protrusions shaped or angled in desired directions, different tread functions may be accomplished.
• the external protrusions cooperate with the reactive upper sole assembly.
• the outer sole may have a hollow downward protrusion below the big toe, that is structured to engage with the ground.
• a void is provided within the protrusion.
• the reactive upper layer also includes a downward protrusion which, when the foot is at rest, is disposed above the void.
• the protrusion in the outer sole becomes rigid and provides a strong lift off point for the foot.
• the user could take a step backward.
• the big toe does not force the active upper sole protrusion into the void or hollow outer sole protrusion.
• the external protrusions do not become rigid and the outer sole does not interfere with the normal gait cycle of the individual.
• the reactive upper sole acts similar to a claw on a cat which may be extended or retracted, as necessary. This action is controlled by the individual's foot, not the sole.
• the reactive upper sole can be programmed or designed to change the operating characteristics of the outer sole.
• the reactive upper sole can be programmed or designed to engage the outer sole depending on the task being performed. That is, if the user is climbing a steep hill, the reactive upper sole can be programmed or designed to engage the outer sole so that pressure from the big toe causes the external protrusions to move downward at an angle to provide a strong or better grip for the outer sole. On a less steep hill, the reactive upper sole may cause the external protrusion to be locked in place, without moving downward. On a decent, the reactive upper sole may not engage the outer sole and thus the external protrusion remains flexible.
• the external heel protrusions can be programmed or designed to be engaged by the reactive upper sole when braking of the sole is required. That is, the external protrusions can be made rigid and forced to move downward at preprogrammed or designed angles.

• a bottom surface of the reactive upper sole 30 is coupled to a top surface of the outer sole 10.
• the reactive upper sole 30 is structured to react to movements by and within the wear's foot, as will be described in further detail below.
• the reactive upper sole 30 includes a first frame 40, a second frame 50, and a third frame 70.
• the first frame 40 and the third frame 70 may be joined for lever functions or linked by a resilient layer for moving function.

• a "flexor" is a frame extension forced to a lever function that flexes from the result of a change in the frame border sections which are programmed with weaker characteristics that share the path of the frame lever arm. Frame lever extensions that meet the border sections programmed limit, force the flex zone to react to the opposing borders that are programmed or designed with more compression limit, less compression limit or no compression limit.
• the weak zone borders altering between different flex limit zones change the extending frame sections direction and lever functions at angles that relay a continual structure change from pressure changes upon the compression limit zones that border these weaker sections.
• the tuberosity at the base of the fifth metatarsal needs to be free of opposing force during the beginning of the stance phase, described below. Therefore, the foot moves forward to find a weak zone in the area proximal to the posterior base of this metatarsal, the posterior section of the weak zone is limited in compression while the anterior weak zone has no compression limit, therefore, the anterior weak zone frame suspends downward while maintaining stabilization from upward pressure from the posterior frame section.
• a "director” is a weaker section of the frame material that allows the frame to torque or twist.
• a "fold zone” is a longitudinal weak section that stabilizes medial lever arm lateral borders and posterior weak flex zone from alternating lateral lever arm and posterior weak flex zone movement during the natural transverse transfer phase from anterior lateral downward pressure to medial toe pressure.
• this fold zone moves the frame to an alternate position from the foot demands for shoe stabilization and control during the natural path in motion of the foot. Therefore, the mid-foot is allowed to maintain in shoe positioning while suspending the transverse arches in the non- obstructing frame suspension zones and mid-foot loft zone.
• the fold zone interacts with the foot which indicates the path change while transferring demands without shifting the mid-foot out of position.
• the frame can shift its anterior lateral lever arm and tabs and anterior medial lever arms medial and lateral borders up and down at alternating angles, this is done without interfering with mid-foot stabilization.
• the movement between the lateral border of the medial lever arm and the medial border of the lateral lever arm is from the longitudinal weak fold zone.

• the first frame flex stabilizer 55 is structured as a weak zone that extends approximately a half inch longitudinally and one inch inwardly. When the foot moves toward the weak zone, the zone suspends the anterior more rigid frame section downward, levering the anterior inner frame of the inner anterior arch upward, controlled through suspension from the stabilized posterior frame bordering section that is locked from a rigid gripping plantar protrusion.

Additionally second frame outer cap 60 compresses the second low compression zone 90 to stabilize the outer side of the sole. Throughout the stance phase compression, third frame protrusions 72 move into outer sole forward portion protrusions 16. This action locks and moves the outer sole protrusions for traction, grip and direction. [083] When transitioning to the toe off phase, the third director 59 flex zone moves the forward portion of second frame forward portion 53 proximal to upward as the rearward area proximal to the third director moves downward.

That is, the frame wraps the inside of the front half of the inside arch, while the side wrap tapers off to not wrap the rear portion of the medial arch.
• the first metatarsal head rolls forward along the suspension pocket of 62.

• the reactive upper sole assembly 30 and the foot bed 600 may be further enhanced when used as the sole of a shoe that moves selected zones of attached upper material, the display shows the concept as a sandal 600.
• the sandal 600 adds additional control functions which act through straps 610, 620, 630, 640 (only diagrammatically shown).
• The. straps 610, 620, 630 and 640 interact with the wear's foot to control the reactive upper sole 30, the foot bed 600, and/or the outer sole assembly.
• the straps 610, 620, 630 and 640 also act as a positioning system, the straps position to border the plantar pockets formed by suspension zones, the straps 610, 620, 630 and 640 and material link to frame connection locations allowing structured side pockets and flex zones that align with the plantar pockets, flex and suspension zones. This forms a positioning pocket that forms to multiple foot strictures that need positioning of the shoes upper wall, as well as suspension positioning on its plantar base.
• the positioning system includes a plurality of pockets and flex zones around the first metatarsal and the fifth metatarsal. These pockets and flex zones center the wear's foot on the reactive upper sole 30 or foot bed 600.
• shoes can be programmed with upper lacing systems that pull fabric around the pocket suspension zone borders. The fabric attaches to the reactive sole assembly 30 at locations that move the fabric away from interference of foot positioning as the frame directors and flexors alternate the shoe upper by tightening and loosening zones during foot guidance during the gait cycle.
• the remote ends, of external fabrics or straps for a sandal can be secured or connected to internal programmed moving structures of the shoe sole so that as the moving structures move toward or away from the outer sole, for example, as a result of the foot guiding the shoe sole during a gait or stride, the external fabric or strap moves in a corresponding upward or downward direction to either increase ordecrease the securing tension that the external fabric or strap exerts on the foot.
• the footbed of the fifth embodiment is incorporated into a sandal.
• the first strap 610 has a first end attached at 611 A to an inner side of the heel portion and a second end extends around the rear portion of the heel of a user and is attached to an outer side (not shown) of the heel portion 612.
• a second strap 620 has a first end attached on the inner side at 621 A of the heel portion 612, slightly forward of the first attachment point 611A.
• the strap 620 crosses over the front portion of the ankle and a second end thereof attached to the first strap 610 adjacent the attachment point of the first strap 610 to the outer side of the heel portion 612.
• a third strap 630 has a first end attached to the outer side of the forward portion 614 and a second end extends over the foot and is attached to the attachment location 621 A for the second strap 620 adjacent inner side of the heel portion 612.
• a fourth strap 640 has a first end attached at 641 A to an inner side of the sole and a second end extends over the foot and crosses the third strap 630.
• a second end of the fourth strap 640 is attached to the second strap 620 adjacent to the attachment point 621 A of the second strap 620 to the inner side of the heel portion 612.
• the straps 610, 620, 630 and 640 can be suitably tightened or loosened, as necessary, as the foot guides the shoe sole to provide added comfort to the wearer of the sandals 600.
• the sole assembly provides a basic structure for the foot to guide a shoe sole in such a way the reduces the internal and external shearing that can occur.
• the shearing can alter many things, including performance, comfort and the foot's natural ability to move along multiple paths.
• the present invention is directed a providing footwear which facilitates the foot following in natural gait path. That is, the present invention provides an improved sole assembly which can be enhanced by programming the sole structures to work with, and not against, the foot.
• the mid sole can be structured with two guidance structures, one for the upper surface closest to the foot, and one for the lower surface closest to the outer sole.
• the foot can then move the upper mid sole sections that move the lower mid sole sections and the outer sole sections. This results in a bi-frame sole structure.
