Definitions

  • the present invention relates to a shoe the structural features of which are such that they allow enhancing the natural suspended heel running technique, i.e., technique in which the first contact of the foot on the ground is with the forefoot and/or with the midfoot, the heel being suspended in the air at that time without touching the ground, thereby assuring the storage of the highest possible amount of elastic energy of the leg and increasing motor performance.
  • the object of the invention is to enable a person or athlete to make the best use of the energy stored in the ankle, specifically the energy provided by the non-contractile parts of the musculature of the ankle, which offer energy for pushing off without any energy expenditure, while at the same time the typical slowing down and the damaging impact that occur when support first occurs on the rear part of the foot (heel) when running.
  • the invention also relates to the method for facilitating adaptation to the natural running technique, generating the efficient stride for the runner, specifically by means of the stages of familiarization, integration, progression, adaptation and consolidation, which necessarily require the use of the shoe of the invention, for the purpose of eliminating or reducing the negative phase of the stride and using the elastic energy accumulated in the non-contractile parts of the extensor musculature of the ankle.
  • the contact time of the foot on the ground is greater than when the entire sole of the foot, including the heel, is supported, and therefore it will take longer to push off again and thus start into a new stride, which impairs performance.
  • the shoe proposed herein is characterized in that the sole and midsole thereof take up only the front part, the heel having been eliminated.
  • the sole and midsole take up only the front and middle parts of the shoe, the midsole having a cushioning function.
  • This new concept is envisaged for being applied in shoes created so that runners today can learn to run better and faster, imitating how African athletes run, who do so by applying the most natural technique that exists, i.e., running barefoot, but furthermore with the use of the shoe of the present invention, more elastic energy can be stored than when running barefoot since the ankle is suspended in the air at all times, particularly when the sole of the foot is completely parallel to the ground or when the ankle joint is bent less than 90o.
  • the heel is raised or suspended in the air, such that the shoe provides a good fit with respect to the foot, and furthermore suitable cushioning, making it easier for the runner to support the foot only on the front and middle regions of the foot in each stride. Since the runner's heel cannot be supported as said part has been eliminated from the sole and/or midsole, the slowing down as well as excessive load caused by said support are reduced, and the storage and release of the elastic energy stored in the non-contractile parts of the extensor musculature of the ankle in the form of a pushing off force is favored, thereby improving the motor performance caused by the front support of the foot and allowing a change in the running technique.
  • the entire support of the foot while running is concentrated in the front part thereof, and better efficiency in the receiving, cushioning and push off of each stride is achieved.
  • the shoe can receive complements in the rear part of the sole and/or midsole, with interchangeable sections, i.e., in the second embodiment of the shoes, supplements or complements of the sole and midsole have been envisaged for their insertion in the rear part, specifically in the hindfoot region, for the purpose of being able to partially or completely cover this rear part.
  • the midsole and/or sole located in the forefoot and/or midfoot can also be made up of just one or several sections or modules, which can also be attached to or separated from one another, these modules furthermore being fixed and/or movable for the purpose of being able to be removed and attached by means of any type of anchoring or securing. These modules can also be moved from one part to another, or even turned.
  • any segment located in the midfoot and/or hindfoot of the shoe can be different from one another as regards size, width, length, height, thickness, depth, shape, form and density.
  • the muscular force will be intensified and the running technique and stride frequency will also be improved, because when one or several segments or complements of the sole and/or midsole are eliminated from the midfoot region, in this second embodiment variant, the heel is suspended in the air, generating a certain 'floating' that favors using the elastic energy accumulated in the non-contractile parts of the extensor musculature of the ankle to generate greater push off in the stride.
  • stride frequency/speed will improve the less sole surface there is in the shoe, i.e., the more sections that have been removed, because with it there will be a smaller contact surface touching the ground and therefore greater speed as regards the take off of the foot from the ground itself.
  • the elastic component that is activated in the soleus and calf muscles due to overstretching allows the storage of elastic energy in the non-contractile parts of the extensor musculature of the ankle, and helps the push off to be greater and more effective.
  • the heel should not touch the ground when using the shoe of the invention without complements.
  • the heel should always be in the air or suspended, even during those times used for walking. Nevertheless, if the athlete is tired the shoe of the invention can be used with the complements of the hindfoot inserted or the runner can sit down to rest.
  • the shoes should not be used without complements for two consecutive days, avoiding the interval series in paths with curves in those stages that contemplate them.
  • the person can, as desired, prolong the duration of each stage, stay in it forever or go back to preceding stages, but it is ideal for the runner to follow the scheduled pace to achieve the objectives set and the best benefits
  • a relevant aspect is that in each of the stages of the method certain parameters are measured for the purpose of being able to confirm that the objectives set have been achieved, and it is possible to move on to the following stage.
  • the instruments used for measuring the set parameters are:
  • Runners that surpass the stage of consolidation using the shoes described in the invention will have achieved using the elastic energy stored in the non-contractile parts of the extensor musculature of the ankle, reducing the negative phase of their stride while running and achieving a natural suspended heel running technique that may allow them to sustain fewer injuries due to this exercise.
  • FIG. 1 a shoe (1) having a tie lace (2), and a sole and/or midsole (3) is shown, Figure 3 showing the silhouette of a foot inside the shoe (1), which foot is indicated with reference number (4).
  • the shoe shown in said Figures 1, 2 and 3 is characterized in that the sole and/or midsole (3) take up the forefoot region and part of the intermediate region, whereas it lacks a midsole and sole in the hindfoot part.
  • Figure 4 depicts the shoe of Figure 3 where the sole takes up the forefoot region (5) and part of the intermediate region (6), provided with an adaptation complement (8) in the hindfoot region (7) without taking up this part completely.
  • the shoe (1) generally shown in Figures 1 to 7 is a shoe the sole and/or midsole of which is eliminated in the rear part so that the person or athlete can only be supported on the front part or forefoot (5), as in Figure 7 , can be supported on the front part or forefoot and/or partially supported the midfoot (5), as in Figure 6 , or can be supported on the intermediate part or midfoot completely and/or the forefoot (6), as in Figure 5 .
  • Figures 8 to 12 both included, show embodiment variants of the shoe (1) in which the midsole and/or sole located in the midfoot can be formed by a single module (6), or several modules (6'), (6'), (6") coupled in the shoe in a fixed or movable manner (removable). Furthermore, the shoe can be provided with adaptation complements located in the hindfoot such as the element (8) shown in Figure 11 .
  • the segment or complement corresponding to the hindfoot (8) can also be formed by two superimposed parts (8'), as depicted in Figure 10 , or said hindfoot part (8) can even have a thickness less than parts (6') or (6") forming the segment of the midfoot (6) of Figure 11 .
  • sections (6) and (8) whether they are formed by single parts or by dual parts, as stated above, can be attached and removed, as desired, for the most suitable use.
  • adaptation complements (6) and (8) and the support complement (9) are fixed and/or movable modules which can be coupled and uncoupled at any time; they could also be moved over the surface of the sole and/or midsole from one place to another, and even be turned, as desired, for the most suitable use.
  • the sizes, shapes, forms, widths, depths, designs, thicknesses, densities, heights and lengths can be different.
  • the measurement is taken by means of instrumented insoles in correspondence with the beginning of the plantar support during supination, as well as during contact with the region of the fifth metatarsal, there being a slight forward inclination of the torso of between 5o and 10o, the measurement being taken with high-speed chambers.
  • instrumented insoles When running continuously for up to 2 km, there will be no contact of the heel (hindfoot) on the ground at least 90% of the time, the measurement being taken with high-speed chambers and force platforms.
  • Figures 13, 14 and 15 show the results of the biomechanical study to know the behavior of the person with the shoe of the invention.
  • Figure 13 shows the depiction of the total plantar support time depicted on the X-axis in a certain percentage versus the measurement of force using as a reference the weight force (body weight) of the athlete on the Y-axis. It can therefore be seen that the shoe of the invention (continuous black line) shows no peak in the vertical ground reaction forces, whereas this peak of the impact does appear when using a conventional shoe (discontinuous line) and a minimalist shoe (gray line).
  • Figure 14 shows how the use of the shoe of the invention (B) allows reducing the contact time of the heel with the ground, thereby increasing athletic performance compared to using a conventional shoe (A).
  • Figure 15 shows the reduction of the number of strides per minute when the shoe with a suspended heel (B) is used instead of a minimalist shoe (A) while running. Therefore, how much one can run increases and athletic performance is improved with the use of the shoe of the invention.
