SHOE WITH INSTEP ELASTIC INSERTION AND INSOLE WITH DEPRESSIONS
Technical field
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
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.
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.

Principle of the invention
The goal of the invention is achieved by a shoe, which 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.
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.
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.
For further increasing of effect of the shoe its upper preferably comprises
in area of an ankle of the foot an ankle elastic insertion and/or 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.
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.
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.

football shoe according to the invention, and the Fig. 16 shoe for skate
according to the invention.
Examples of embodiment
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. la
and 1 b, 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.
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.
CA 02864273 2014-08-08
WO 2013/123922 PCT/CZ2013/000021
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
5
through suitable shaping of insole or its carrying layer and/or openings
performed at least in any of its layers.
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.
Another element of the shoe according to the invention, 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
CA 02864273 2014-08-08
WO 2013/123922 PCT/CZ2013/000021

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.
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.
The Fig. 4 represents a sandal in embodiment according to the invention.
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

As it is obvious from embodiment of a sandal according to the invention
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

there is arranged approximately rectangular ankle elastic insertion 422 for
reduction of pressure on heel of the foot or on Achilles tendon. In upper
section
of the middle part 43 of the upper 4 from behind above the rear part 42 of the
upper 4 is positioned approximately rectangular heel elastic insertion 421,
which
is joined with this part, and which extends up to the opening 6 of the shoe.
This
heel elastic insertion 421 contributes to reduction of toughness of the whole
shoe, through which it supports effect of other elastic insertions 411 and 422
and it itself further reduces pressure of the shoe on the heel or Achilles
tendon.
In not represented variant of embodiment this heel elastic insertion 421 may
be
replaced or added by an opening or lowering. In other not represented variant
of
embodiment the ankle elastic insertion 422 may extend up to the sole of the
shoe 71 while it runs via the rear part 42 of the upper 4, or creates at least
a
portion of transition between it and the middle part 43 of the upper 4. In
other
not represented variant the ankle elastic insertion 422 may be totally omitted
from structure of the shoe. The shoe comprises a sock lining or an innersole
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.
In principle identical layout of similar instep, ankle and heel elastic
insertion 411, 422 and 421 as at the ski running shoe is applicable for
example
also at athletic track shoe (Fig. 14) or at football shoe (Fig. 15), possibly
also at
other not represented types of shoes. Also these types of shoes in various

embodiments may be adjusted to requirements of the user and/or manner of
their utilisation, e.g. by omitting the ankle elastic insertion 422, etc. The
shoes
comprising a sock lining or an innersole 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.
The Fig. 16 further represents shoe of a skate in embodiment according
to the invention. The upper 4 of the shoe comprises enclosed instep 41, as
present types of similar shoes, which however in area of instep of the foot
under
the bootlace 5 and its guidance 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.
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
CA 02864273 2014-08-08
WO 2013/123922 PCT/CZ2013/000021
a depression for Mel 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
5 structure and biomechanics.
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
10 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
15 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.
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.
