     BACKGROUND 
     What is the problem (analog) with conventional shoes? Shoes do not actually work for you. They do not adapt to your moving about with loaded. There is nothing like a good human fit. In 100 years the “mold” has remained the same. 
     What is the problem (digital)? Analysis is typically only conducted with awkward equipment and only in the lab. It results in questionable (or subjective) data dumps. Further, static templates can be copied, lost, or stolen. It also provides very limited real-world sampling.

     DETAILED DESCRIPTION 
     Overview 
     The new shoe is binary. It is separated into two regions of activity, with suspension of the human body as a physical differentiator, as illustrated in  FIG. 1 :
         1) the body of the shoe: the upper  1  and the cradle  2  (the upper/Down under combination); and   2) the shoe&#39;s chassis: perimeter sole  4 , blade  5 , energy return system  12  (omitted from  FIG. 1  for the sake of clarity) and sleeve  8 .       

     Our footwear (footware, as we&#39;ve called the new shoe) has broken the known way for manufacturing shoes, and introduced a new way for people to interact with their shoes. It&#39;s centered around a continuously changing form, as it will change according to how the user is acting as they go over the ground. The regular shoe is centered on using the last, with many people involved in the process, usually done in low pay areas around the world. Our shoe is not constructed this way. 
     Body 
     In one embodiment, the body of the shoe has the following construction: 
     Upper: 
     It  1  is made of leather or fabric or other materials, just like materials current uppers have. 
     The upper  1  is physically, dimensionally larger than the foot cradle  2 , in both length and width. There needs to be enough of a size difference for energy return system  12 +blade  5 , as described below, to fit into this space (which we are calling Timing space). 
     It has a firm strip of material (a Rail  9 ), likely a nylon material (though many other polymers are possible choices), that runs around the leading edge of the upper, on the inside. This strip of material is attached—with glue, sewing or other means, and this strip may be composed of several parts. 
     It may be a part of a structural piece that&#39;s flush with the inner surface of the leather. 
     This strip is configured to anchor the narrow ties  3  that lie between it and the cradle  2 . 
     Foot Cradle (the “Down Under”): 
     The Foot Cradle  2  is the foot bed, where the foot goes. 
     It is like a hammock, sling, or carriage, in a basic physical description, but much more complex, in that it has the unique property of being responsive at varying locations along its perimeter as illustrated in the series of views of  FIG. 2 . These are called domain areas as they work with the tie  3  and other parts that lie in the same area at ‘that point’ within the shoe. 
     It can be designed to conform closely to the bottom of the foot. 
     It has a firm strip of material (rail  10 ), like that of the Upper, that runs around the perimeter, this time on the outside of this cradle  2 . 
     This strip  10  parallels the strip  9  on the upper  1 . 
     The cradle  2  could be built from various materials (nylon, woven mesh, gore tex, rubber . . . anything that can be thought of really, so long as it has the bed of it, with the bottom of it just to the other side of the bed, thus pointing to its material and all of it suspended). 
     This cradle  2  could have numerous embodiments and materials. 
     In cradle  2  construction, the forefoot, mid foot and rear foot can all have varying degrees of flexibility, stiffness or even hollowed out as depicted by  2   a ,  2   b  in views  2 . 1  and  2 . 2  or raised up parts  2   c ,  2   d ,  2   e ,  2   f  as shown in views  2 . 1 ,  2 . 2 ,  2 . 3  and  2 . 4 . 
     It&#39;s possible to have different materials placed between the foot and cradle. 
     For instance, materials that add a rise  2   c ,  2   d ,  2   e ,  2   f  or that of a depression  2   a ,  2   b  can be added to the foot cradle  2  material. 
     In one embodiment, a ridge or horizontal shelf  28  will run around the foot cradle  2 . This ridge  28  could have different materials with different strengths placed on it. This way you can have a variety of foot cradle materials/embodiments for specific foot conditions (see  FIG. 2.2 ). 
     In another embodiment, of the above, the cradle  2  could be built with a type of ‘long’ hook system, for a place to snap-in the foot cradle. 
     The sides of the cradle  2  may be thinner than what is making up the foot bed. In fact this is amongst the most likely scenarios, as in these cases the rail ‘part’  10  is now part of the sides of the cradle  2 , as illustrated in  FIG. 3 . (In other words; the bed and bottom of a cradle is one thing, the sides and its rail another thing. One other embodiment.) 
     Each part is designable to various conditions and requirements. 
     As shown in  FIG. 3 : 
       3 . 1  This is an embodiment where no plate is being used. The entire shoe&#39;s contact is experienced through the perimeter sole  4 , with its telemetry ‘sent’ to the sides of a foot; 
       3 . 2  Emphasis on cradle  2  conforming to foot. Thick leather, stretchy material, anything that conforms to the foot. 
       3 . 3  In this embodiment both plate  11  and cradle  2  is emphasized. This cradle  2  shows how stiffness can be applied to the cradle  2 , either partially or wholly. 
       3 . 4  In this embodiment the plate  11  can be built up. Depending on assessment the plate  11  could be built up in certain places only. 
       3 . 5  This embodiment shows how the cradle  2  and plate  11  could be built as one unit, with space between the two. This is as close as we come to a midsole. This embodiment would see the stiff plate  11  connected to, in someway, the foot cradle  2 . 
       3 . 6  In this embodiment the foot cradle  2  is shown to have reinforcements placed in it. Or this could be a ‘hollowed place’ on the cradle. In back it&#39;s built up on the inside. 
     Tie: 
     Ties  3  are narrow and short members that connect the upper  1  and foot cradle  2  together at various points around the shoe (see  FIG. 4 ). Most likely they are fibrous and somewhat stiff. 
     They are most likely evenly distributed around the foot, but for the highly motivated they could be tied to where a person has a joint that needs particular attention. For the athlete these ties  3  would be adjustable; which would make all the domain parts adjustable too. 
     Ties  3  are connecting the larger upper  1  with the smaller foot cradle  2 . 
     In other words; the ties  3  connect the cradle/carriage  2  to the upper  1 . 
     It may be permanently attached to the upper  1  or foot cradle  2  through the stiff rails  9 ,  10  as illustrated in  FIG. 4  (although rail  9  is omitted from  FIG. 4  for the sake of clarity), or possibly made to hook, or slide, into a fixed area on the rail  9 ,  10 . 
     Primarily the tie  3  will travel, under the load of a person, through the stiffening blade  5  and the energy return system  12  (not shown in  FIG. 4 ). 
     The tie  3  moves vertically based on amplitude of force strike. 
     Chassis 
     Perimeter Sole (illustrated in  FIG. 5 ): 
     At its base the strike force is absorbed by this component  4 . 
     At a basic level this is the part that reacts to the foot&#39;s strike force, as it now includes the reaction from the ground, the part of it directly beneath each tie&#39;s  3  (omitted from  FIG. 5  for the sake of clarity) domain. 
     In one embodiment there may be a part (a foot Plate  11 ) that is housed within the perimeter sole  4 , that will then add to the perimeter sole  4 , making a full soled shoe 
     In one embodiment, a full sole plate  11  can be screwed, clicked in, snapped on, etc., over the entire perimeter sole  4 , on the outside of course. 
     The exterior portion of this sole plate  11  may be flexible (so it can bend over small extrusions (could be rocks etc.,) of the grounds topography. 
     It could be segmented physically or have stiff portions connected with softer portions. 
     Segmentation could allow for partial rotation of the segments. 
     Segments could be inter-locked like a ball and joint, so they more readily grip various ground angles. 
     Note there is always space between the bottom of the foot cradle  2  and the top of the footplate  11 . 
     Embedded in the rim of the perimeter sole  4 , whether segmented or not, is a slightly wide, as a vertical measure, ribbon like blade  5  (see below also illustrated in  FIG. 6 ). 
     In one embodiment the blade  5  can be sandwiched by the perimeter sole  4 , meaning the perimeter sole  4  will have two edges. In some embodiments, we could have places along the blades length  5  where it has ‘screwed in’ axes, allowing a control of where it bends. 
     At the top of the perimeter sole  4 , and on the inside, considering the blade  5 , there is a groove or shelf that is set for the base of the energy return unit  12 . In some manner this is set up to hold the base of the hard driver  12 . 
     Blade: 
     It is a vertical piece of plastic, also illustrated in  FIG. 6 , likely a nylon, that is embedded near the outer rim of the perimeter sole  4 . 
     It may be removable from the perimeter sole  4 , or not, and it may be segmented or not. It could have soft sections, for where the shoe bends. 
     For the most part it is required on both sides of the foot—the very front and back is not necessarily needed, as it bends in the perimeter sole  4  when both sides go one way—and then another—as the person plants their sole, at times, angled away from the vertical stance and movements 
     This points to the duality of the blade  5 , since it can angle itself, going from one direction to another, depending on how the foot is angling itself during a stride. 
     One major descriptive point: the upper portion, or zone, of this component fits between the upper  1  and cradle  2 . The vertical portion of the blade  5 , that is used for travel, fits between, usually, the bottom of the upper  1  and the top of the perimeter sole  4 . This distance can be anywhere between a third of an inch and three quarters. The blade  5  will be even higher (two inches, or more) for military and army type boots, where more stability/control/strength is needed. 
     One of the main purposes for it is controlling for lateral instability. 
     Of central importance are the vertical cut-outs (slots)  6  in the blade  5  that act as a guide for the tie  3 . 
     Each of these cut outs  6  guides the vertical travel of the tie  3 . There is a cut out  6  for each tie  3 . 
     Note that the cut-outs  6 , also illustrated in  FIG. 6 , may be in a sliding portion, wafer thin, of the blade  5 ; or they may be in short sections, that once put together are making up a whole blade  5 . 
     And note the cut-outs  6  may be in various shapes. 
     In the illustrated embodiment (see  FIG. 6 ) there are three horizontal zones for the blade  5 : one, the embedded part that fits in the perimeter sole  4 ; two, the mid zone where the body moves up and down against it; and three, the part that fits into the body parts of the shoe (in the Timing space). 
     The blade  5  can be a consistent height around the shoe, but can work/embrace different heights within the one shoe. 
     Energy Return System (the “Hard Drivers”): 
     As an overview of its purpose: each of the energy return systems  12 , as in one unit, must have a specific impact strength that can receive the energy charge from the foot loading, and then return it as the pressure is lessened. This system transforms, in a sense interpreting, the forces that are being applied. 
     Referring to  FIG. 7 , the ERS  12 , or driver, has a wafer thin, vertical, and stiff frame  13 ; it&#39;s open at the top with an interior space. This space is a zone, designed to allow the new shoe ties  3  traveling room within it. They can move vertically, though slight deviations are allowed. Ties  3  will go downwards first, against the resistance strength of the ERS  12 , and then back up. 
     On both sides of this vertical frame  13  there are generally flat and extensible/tensor  14  polymer units (likely two to each side, one on either end of the opening—two on the inside and two on the outside of the frame  13 ). 
     Different strengths for the ERS units  12  are pointing to these tensor units  14 . 
     Thickness and lay-up of the polymers, with different amounts of carbon in the elastomerbase, for instance, and even the size and thickness, as well as outer shape, will combine to produce ERS units  12  of varying strengths. 
     Between these tensor units  14  there is a semi pliable—somewhat stiff bridging unit  15  (wing) that lies within the interior space (flush on both sides). It&#39;s fibrous so it does not stretch. It should only bend. 
     The bridge unit  15  is what supports the tie  3 , and thereby that portion of the human body&#39;s weight that is bearing down on just that particular area in the shoe (which, for us, are called domains: the tie  3  is the center and the immediately adjacent materials around it, regardless of what layer they are in, are a part of each domain). 
     The tensor units  14  are never pinned to each other, but only to the frame  13  with one lock-pin  16  and to the bridge unit  15  with another lock-pin  16 . 
     All of the pins  16 , the eight of them in the illustrated embodiment, are meant to allow rotations (small arcs) in tensor units  14 , which allows and controls the down and up movements of the bridge  15 . 
     There&#39;s a mathematical relationship between where the pins  16  are, both in the frame  13  and the bridge  15 . A front tensor  14  will widen when the load is taken on, and the tensor  14  in back of it will lengthen. This process gives the pin  16  placements a kind of “X”, or scissor action. 
     The arrangement allows one to maximize the tie  3  travel, while minimizing the distortion in tensor units  14 . 
     It means the makeup of the polymers, the ones that make up the tensor units  14 , are managed by making them stay within their plastic limit. 
     The tensor units  14  themselves can be designed in many ways—the size of the tensor units  14  can vary, as there is not much of a bounding limit (just the envelope of space we are calling Timing space). As well, the pins  16  too can be different diameters, and different thicknesses. 
     The pins  16 , illustrated in  FIG. 9 , right-hand view, can be lock pins  16  (our choice), and angled (like an hour glass) so as to lock in place, keeping locked the tensor unit  14 , frame  13 , bridge  15  combination. 
     Other embodiments for the energy return system  12  are varied (as shown below). 
     In one embodiment (see  FIG. 8 , far left  8 . 1 ) the tie  3  goes through an energy return system  12  (omitted from  FIG. 8 , but as described above). 
     In another embodiment (see  FIG. 8 , middle image  8 . 2 ) a short length of connector material  17  replaces the tie  3 , the ERS  12  in this system longer and more like an amalgam of materials that may be likened to materials of today, that are already going into the makeup of a shoe. 
     In the last embodiment (See  FIG. 8 , right image  8 . 3 ) a belt system  18  replaces the unit type of energy return system  12 . A belt system  18  might replace the need for the stabilizing blade  5 , as it could incorporate stiffening units within it. An overhead clasp  19  would connect the foot cradle  2  and upper duo  1 ,  2  to the belt system  18 . 
     In the embodiment below (see  FIG. 9 ), the blade  5  and an energy return system  12  are built as one. 
     In these embodiments (See  FIG. 10 , below), considered for the heaviest of duty footwear, the energy return systems  12  may be either reinforced with metal  13   b , or completely built from it. 
     In another embodiment (see  FIG. 11 , above left  11 . 1 ) there is a scissor-like version of the energy return system. Hard members  20  criss-cross to either side of the tie  3  (each of the four ERS&#39;s seen in  FIG. 11.1  are showing an end view of one tie  3 ). Load actions will squeeze the polymer units  26  to either side of the tie  3 , thus providing vertical travel. In the second embodiment (see  FIG. 11 , above middle  11 . 2 ) the tie  3  pulls at two of the arms  27  in the polymer mix, and simultaneously presses on two  27 . A stiff frame  21  circles the whole unit. 
     In the third embodiment (see  FIG. 11.3 ,  11 . 4 , the two above right, showing a ‘before’ and ‘after’) the polymer body  24  bends (only with pressure applied), as the tie  3  sits over a semi-stiff bar  22  that also bends under the load pressure. Both polymer elements  24  here are held in place by a stiff bottom  23  (possibly metal), likely with pins  25 . 
     Sleeve: 
     The sleeve  8  is there to cover for all of the inner workings (inner moving parts) and it&#39;s pictured here in a wide red band, or ribbon. It&#39;s elastic in the main embodiment, probably waterproof, and it gets fixed within the leading edge of the upper  1  and against the side of the blade  5 , between it and the inside edge of the perimeter sole  4 , where it clasps the blade  5 . 
     It circles the foot and covers the blade  5  (the central part of it that would otherwise bare). 
     It is ordinarily both flexible and elastic, but there are other embodiments where it&#39;s under the upper  1  altogether. In this latter case the upper  1  is long on the sides, traveling down the outside of the perimeter sole  4  during loading and unloading in shoe action. 
     It allows breathability for the shoe, and ultimately the foot. 
     The material of the sleeve  8  could match that of the shoe, in both looks and functions; the specific environmental conditions expected are a part of the design brief. 
     It&#39;s up against the blade  5 , but is not glued to it, or attached to it. The sleeve  8  can have a variety of designs. 
     In many commercial embodiments the upper&#39;s  1  leading edge is covering the mid zone of the blade  5 , thus hiding the sleeve  8 . When movement occurs the upper  1  will travel over the top of the perimeter sole  4  (as also mentioned just above). 
     Manufacturing: 
     Our footwear does not require it to be built on a last. Each of the components of the illustrated embodiments can be configured to be produced on a production line. When they are assembled, there will be little need to have a lot of people handling them. Much of it may even be done at point-of-sale, because, for many, the shoe is something that is fitted to their exacting requirements, both for functional and aesthetic reasons. Many will still want the appearance of the pre-assembled; so for these cases there can be a sort of ‘dummy’ shoe that would only need the drivers  12  inserted (with a special hand tool, designed just for this purpose), and some sort of trial period during the fitting stage. 
     So, yes, it can be pieced together, like on an assembly line. 
     The perimeter sole  4  can have a segmented configuration, either in short pieces, or in whole chunks covering a major portion of the shoe (the forefoot, say). Another segmentation might be ‘soft’ areas between harder ones, where the ‘joint&#39;s’ might act as couplings, similar to what lies between train cars. Or, we could have the perimeter sole  4  just a narrow version of what&#39;s already present in shoe soles, depending on the flexibility to interact with the blade  5  and body combined. If it was segmented it could be snapped together. The blade  5  could then be inserted, and the energy return devices  12 , with ties  3 , could be placed with the rail system  9 ,  10 , already attached to their respective parts. 
     In another embodiment, our footwear is configured to shift what a show can do. The shoe and associated technology are configured to extend to analysis, identify and tracking. 
     The travel zone I region of our footwear is where the tie  3  that is connecting the upper  1  and cradle  2  together, moves through the energy return system  12 . In an adult shoe there are (likely)  24  places of vertical travel. 
     When we monitor this vertical travel zone with a method that follows every incremental movement of each and every tie  3  as they go downward in the cut-out zone  6  and back up again, we will get a rich level of data. We might mark the travel using a feedback loop, transducer, etc. By doing so we have a data output of a large magnitude. All that is needed is some form of counter that marks the increments as they occur. Like a ruler, each point of vertical travel must be designed for capture, with calculated references. In the shoe each travel zone, within the cut-outs  6 , can be noted to have, for instance, 300 dpi. This collected information, as the ties  3  moved along, at every travel zone is collected and sent to an AID converter/chip that would be best seen in one side of the shoe. The information can then be sent, wirelessly, to a central location with software, to analyze the generated data for various applications. Many applications will have this location within their smart phone. Others will have it within a station in a secured area for instance. 
     If we can think of every travel zone as having  10  places (theoretically like notches) of definable travel, and you multiple that by 24, you would get 24 to the power of 10 in possible mathematical outcomes in every given instance of one&#39;s foot cycle. That is one instance; when you take that amount of data and multiple that over a period of seconds or minutes, the richness of data output would be more than adequate for most all of our pictured applications. 
     With this richness of data, and once all of the noise and variables are logarithmically figured out, the data can be utilized for various applications. 
     With this data we will be able to locate, pinpoint and define patterns of walking and general movement. Once this occurs our footwear will then generate a behavioral biometric identity, based on the cadence of a stride. The users electronic ID in other words. But this is only the beginning So many of these are possible, coming from the same collection of a person&#39;s travel, that they can have an ID that is different for one application than it is for another. Plus, this multiplicity of identifying numbers allows one to discard one, and then another one; anytime there is a chance for a compromise in the system they are sending it to.
