Technical field
[0001] The invention relates to a shoe comprising a sole on top side of which there is mounted
an insole to which an upper of the shoe is attached.
Background art
[0002] At present number of various types and structures of shoes is known. Their common
disadvantage is that tough upper (whose toughness is quite often increased by connecting
element/elements), which is firmly attached to the sole of the shoe, causes during
walking unnatural and extreme load of foot instep and consequently also of all muscles
and ligaments of the foot. As a result of this, also by healthy human with normally
shaped foot, next to others, callosities are created, function and load of Achilles
tendon is changed, functioning of protractors (extensors) and flexors of toes, especially
of big toe, is reduced, hammer toes are created, and gradually longitudinal arch of
the foot may collapse, thus the flat foot may evolve, and its vascular, lymphatic
or nerve system may be even damaged. These processes are moreover worsened when plane,
possibly towards the toe cap lowered insole is used, which further contributes to
unsuitable load of the foot through unnatural distribution of weight of human body
into the whole surface of the foot, instead of its distribution among supporting parts
of the foot - the big toe joint, toe joints and the heel bone. Next to physical pain,
accompanying effects of these changes which gradually penetrate not only into the
whole lower limb but also into the whole body, are an excessive fatigue and psychic
problems, which lowers quality of life.
[0003] The goal of the invention is to design a shoe, which would remedy the drawbacks of
shoes of present structures, would reduce load of instep and enable the most natural
distribution of weight of human body to those parts of foot which are adapted to this
purpose.
[0004] EP 2 316 292 A1 discloses a shoe with elastic insertions on its upper.
Principle of the invention
[0005] The goal of the invention is achieved by shoe according to the appended claim 1,
this shoe also comprises a sole, to which there is attached an upper of the shoe,
and on whose upper side an insole is mounted, whose principle consists in that, the
upper of the shoe comprises in area of instep of the foot at least one instep elastic
insertion, which reduces pressure of the upper of the shoe on the instep of the foot,
while the insole on its upper side comprises at least a depression for big toe joint
and a depression or lowering for heel bone. Synergetic action of these elements then
ensures proper distribution of weight of human body among carrying elements of the
foot, thus natural load of individual parts of the foot respecting its structure and
biomechanics.
[0006] Especially at boots it is then advantageous, if the instep elastic insertion is on
section of its length provided with longitudinal opening, which further reduces its
toughness, possibly if in the area of the instep of the foot it comprises two side
by side arranged instep elastic insertions.
[0007] To increase the effect of the instep elastic insertion, the upper of the shoe may
further on at least one side of the shoe in the area of the instep of the foot comprise
an auxiliary instep elastic insertion.
[0008] For further increasing of effect of the shoe its upper comprises at least on one
side of the shoe in area of an ankle of the foot an ankle elastic insertion and/or
preferably in area of the heel, or above the heel a heel elastic insertion, which
reduce overall toughness of the shoe, and especially upon full treading also load
of the heel, or more precisely of Achilles tendon.
[0009] The heel elastic insertion then may be especially at boots with advantage substituted
by a calf elastic insertion, which reduces load of the calf and of calf muscles.
[0010] At all variants the highest effect is achieved upon usage of an insole which on its
lower side in heel section comprises a heel protrusion arranged under a heel depression
on its upper side, which is from outside delimited by a deflection of cuboid bone
arranged under a support of cuboid bone on upper side of the insole, and on which
ties together a protrusion of longitudinal splint bone arranged under a depression
of longitudinal splint bone on upper side of the insole. On the protrusion of longitudinal
splint bone then ties together a protrusion of little toe joints arranged under a
depression of little toe joints on upper side of the insole, which runs via a deflection
of support of transverse arch towards inner section of the insole into a protrusion
of big toe joint arranged under a depression of big toe joint on upper side of the
insole, while the support of transverse arch creates a flexible bridge between section
of insole under big toe joint and under little toe joints, and towards the heel of
the insole on this support ties together a support of longitudinal arch of the foot,
which from lower side of insole is formed of a deflection of support of longitudinal
arch arranged under the protrusion of support of longitudinal arch of the foot on
upper side of the insole. This insole secures the most suitable distribution of body
weight between the carrying elements of the foot, and thus natural load of its individual
parts.

Examples of embodiment
[0012] The shoe according to the invention with its structure and properties fully respects
morphology of human foot and its biomechanics, while it enables its natural poise
and proper load of all its parts. As it is apparent from the Fig. 1a and 1b, which
schematically represent the foot skeleton when standing or during walking wearing
the shoe according to the invention, the instep is not loaded excessively and the
transverse arch does not collapse, like at usage of present types of shoes - Fig.
2a and 2b, thanks to which the protractors (extensors) and flexors of toes as well
as the Achilles tendon and further muscles or ligaments of foot are fully functioning
and they are properly and naturally loaded. Wearing of the shoe according to the invention
helps to prevent number of health problems, affecting not only the foot itself, but
they may consequently affect also other parts of the body, especially other parts
of legs, the spine, etc.
[0013] The shoe according to the invention is based on synergetic joint action of several
elements. The first of them is the insole, which is in the shoe mounted according
to requirements in a fixed manner (innersole) or in a removable manner (sock lining),
and which on its upper side comprises at least a depression for big toe joint and
a depression for heel bone. Thanks to these depressions this insole maintains the
foot in its natural position and facilitates proper distribution of weight of human
body among its main supporting points formed of big toe joint, toe joints and heel
bone. Lowering of heel bone simultaneously helps to achieve proper position of the
whole leg, which brings relief not only for its so far extremely stressed parts, especially
ligaments and joints, but also for spine, thus uprights human body and transfers its
centre of gravity into natural position. In various variants of embodiment the insole
next to the depression for big toe joint and the depression for heel bone may be provided
with further elements like e.g. a protrusion for support of longitudinal arch, etc.
[0014] At single layer insole the depression for big toe joint and for heel bone is performed
either through suitable shaping, e.g. depression and/or change of thickness of insole
in places of these recessions and/or openings performed in the body of the insole.
At multilayer insole these recessions may be also formed through suitable shaping
of insole or its carrying layer and/or openings performed at least in any of its layers.
[0015] The most suitable insole, which brings the best results, is the insole known e.g.
from the
CZ patent 298894, or analogic
EP patent application 1854371, which from the lower side features a shape of bottom part of human foot (the sole)
and from the upper side a shape of impression of bottom part of human foot. The lower
side of insole then in the heel section comprises a heel protrusion arranged under
a heel depression on upper side of the insole, which is from outside delimited by
a deflection of cuboid bone arranged under a support of cuboid bone on upper side
of the insole, and on which ties together a protrusion of longitudinal splint bone
arranged under a depression of longitudinal splint bone on upper side of the insole.
On the protrusion of longitudinal splint bone ties together a protrusion of little
toe joints arranged under depression of little toe joints on upper side of the insole,
which runs via deflection of a support of transverse arch towards inner section of
insole into a protrusion of big toe joint, arranged under a depression of big toe
joint on upper side of the insole. Simultaneously the support of transverse arch creates
a flexible bridge between a section of insole under big toe joint and under little
toe joints. Towards heel of insole on this support ties together a support of longitudinal
arch of foot, which is from the lower side of insole formed of a deflection of the
support of longitudinal arch arranged under a protrusion of support of longitudinal
arch of foot on upper side of insole. In embodiment according to the
CZ patent application 2009-580, or analogic international patent application
WO 2011023148, the heel part of this insole with heel dimple is further lowered towards its middle
section by means of recession or lowering.
[0016] Another element of the shoe, which jointly cooperates with the insole is at least
one biomechanical elastic insertion
1 (a spring) created from elastic material, which is incorporated in the upper of the
shoe in area, which is in contact with instep of the foot, while it extends, as per
the type of the shoe, up to the edge of the instep or to the opening in the shoe,
or to transition of instep of the shoe into middle or rear portion of the upper of
the shoe. This insertion with advantage is performed as multilayered one, when it
from outer side contains folded layer
2 of material from which the upper of the shoe (e.g. leather) is produced, this being
firmly attached for example sewn together with under it arranged elastic layer
3 (e.g. a textile rubber), that renders to it suitable elastic properties - see the
Fig. 3. In preferred example of embodiment designed especially for enclosed shoes,
on surface of the elastic layer
3 adjacent to the inner space of the shoe there is further positioned a layer of hydrophobic
or waterproof material, e.g. neoprene, etc. Another applicable structures of biomechanic
elastic insertion
1 are, based on the above mentioned facts, apparent to an average person skilled in
the art, and that is why they will not be described hereinafter.
[0017] According to the type of shoe the elastic insertion/insertions
1 positioned in area of instep of the shoe may be added by another ones, as to the
structure identical or similar elastic insertions
1, positioned in other parts of the shoe, as it further will be described and illustrated
on several particular types of shoes. As it is apparent from the below mentioned exemplary
embodiments of the shoe according to the invention, the shape, size and individual
positioning of any of the elastic insertions
1 are given by the structure and design of the shoe, shape of its parts, its size and
purpose, though in various examples of embodiment they may differ.
[0018] The Fig. 4 represents a sandal. The
4 upper of the sandal at the same time contains opened instep
41 as common types of similar footwear formed of straps
410 of material, in represented example of embodiment of two straps
410 running over instep of the foot, and a rear part
42 formed of a strap
420 running around the heel or above the heel of the foot. The middle section of the
strap
410 of instep
41 closer to ankle of the foot, which during walking is in a close contact with instep
of the foot, is along the whole width formed of an instep elastic insertion
411 of the above described structure. This elastic insertion
411 when stepping out or more precisely in the first phase of step gets into close contact
with instep of the foot, and thanks to its elastic properties it adjusts to its shape
and motion, so it does not exert unproportionally high pressure on it, as it is by
present types of shoes. The second of straps
410 of instep
41 being without elastic insertion
411 then ensures sufficient stability of sandal on the foot. The heel elastic insertion
421 of the same structure then in the represented example of embodiment creates section
of the strap
420 running over the heel or above the heel, through which not only an overall toughness
of sandal is reduced and proper effect of the instep elastic insertion
411 is supported, but simultaneously based on the same principle, loading of the heel
or more precisely of Achilles tendon is reduced upon full treading. In the not represented
examples of embodiment of sandal the sandal does not comprise the heel elastic insertion
421, possibly does not comprise the rear part
42 of the upper
4 at all thus it is performed as a slipper, and/or comprises another at least one instep
elastic insertion
411 positioned in the second of the straps
410 of instep
41. Sandal or slipper comprises the sock lining comprising on its upper side at least
a depression for big toe joint and a depression for heel bone, in preferred embodiment
the insole according to
EP 1854371 or
WO 2011023148.
[0019] As it is obvious from a sandal represented in the Fig. 5, initially one instep elastic
insertion
411 may be, e.g. due to functional or decorative elements of sandal, positioned outside
the upper section of its instep
41, possibly may be replaced by at least two otherwise positioned instep elastic insertions
411. In the represented variant of embodiment one of the instep elastic insertions
411 is positioned in vicinity of upper section of the strap
410, along its whole width, while the second, approximately in a shape of rectangle, is
positioned lower in the instep
41 of sandal. In other not represented examples of embodiment of sandal the sandal does
not comprise the heel elastic insertion
421, possibly does not comprise the rear part
42 of the upper
4 at all, thus it is performed as a slipper, and/or comprises another at least one
instep elastic insertion
411 positioned in the second of the straps
410 of instep
41. Sandal comprises the sock lining comprising on its upper side at least a depression
for big toe joint and a depression for heel bone, in preferred embodiment the insole

51 is provided with approximately rectangular instep elastic insertion
411, which extends up to the opening
6 of the shoe. For overall reduction of toughness this elastic insertion
411 is provided along a portion of its length with longitudinal opening
4110, preferably with rounded end. On at least one side of the shoe approximately in place
under the ankle in transition between the instep
41 and the rear part
42 of the upper
4 there is arranged approximately triangular ankle elastic insertion
422 for reduction of pressure on the heel of the foot or Achilles tendon. In the upper
section of the rear part
42 of the upper
4 from behind is positioned approximately triangular calf elastic insertion
431, which extends up to opening
6 of the shoe. This calf elastic insertion
431 contributes to reduction of toughness of the whole shoe, through which supports effect
of other elastic insertions
411 and
422, and it itself further reduces pressure of the shoe on the calf or the calf muscles.
In not represented variant of embodiment this calf elastic insertion
431 may be replaced or added by opening or lowering. In other not represented variant
of embodiment the ankle elastic insertion
422 may extend up to the sole
7 of the shoe, while it is running over the decorative frame
71 of the shoe and/or creates at least a portion of transition between this frame and
the rear part
42 of the upper
4. The shoe comprises a sock lining or an innersole containing on its upper side at
least a depression for big toe joint and a depression for heel bone, in preferred
embodiment the insole according to
EP 1854371 or
WO 2011023148.
[0030] In all above described types of shoes is positioned a sock lining or an insole, which
on its top side comprises at least a depression for big toe joint and a depression
for heel bone, and which in synergetic combination with elastic insertions
411, 422,
431, or
421 positioned in the upper
4 of the shoe or with at least one instep elastic insertion
411 considerably reduces till this time unproportional load of individual parts of the
foot, while it respects its natural structure and biomechanics.
[0031] The above described embodiments of the shoe according to the invention are illustrative
only and they serve to explain the principle of the invention. In structurally different
embodiments of the same types of shoes then individual elastic insertions
411, 422, 431, or
421 may be positioned between another portions of the upper
4 of the shoe and/or they may be created in other shapes as per individual shapes of
these portions, or their transitions, possibly some of these elastic insertions
411, 422, 431, or
421 may be omitted, or contrariwise may be replaced by higher number of elastic insertion
with the same or similar effect, possibly provided with longitudinal opening. Based
on the above mentioned facts, these modifications are obvious to an average person
skilled in the art, therefore they will not be described here in detail. In any case,
the principle of the invention is the shoe, comprising the insole provided on its
top side at least by a depression for big toe joint and a depression for heel bone,
whose upper
4 at least in place of instep of the foot is provided with at least one instep elastic
insertion
411 for reduction of pressure on the instep of the foot, possibly as the need may be
with at least one ankle elastic insertion
422 and/or calf elastic insertion
431, or heel elastic insertion
421 for reduction of pressure on further parts of the foot or the leg. The instep elastic
insertion
411 in case of need, may also be added by at least one auxiliary instep elastic insertion
412, and it may be running totally outside the tongue
8 of the shoe, or it may extend into it, possibly it may create the whole tongue.
[0032] Next to the above described benefits, when wearing the shoe according to the invention,
the biopolarity of magnetic field of user's body is changed, which means that the
shoe according to the invention in its all embodiments supports and maintains natural
biomagnetic field of user's body and in case of its impairment it creates and/or restores
the same.
