[0001] The objective of this invention is a shoe insert comprised of multiple shock absorbers
for the foot while achieving a sensation of well being and comfort.
PRIOR STATE OF THE ART
[0002] Presently there are different types of shoe insoles that exist with shock absorption
properties, which are generally based on the insertion of a spring or other similar
shock absorption element into the shoe insole. However, these solutions are technically
complicated because they require complicated manufacturing processes.
[0003] Among the shock absorption inserts we have the
PCT W09947014 which describes an insert with multiple support elements that provide shock absorption
in combination with an air chamber that is created between the two parts that make
up the insert. Also, these support elements are interconnected through many air passages.
EXPLANATION OF THE INVENTION
[0004] The shoe insert that is recommended by this invention consists essentially of an
insert, manufactured as one piece of polymeric material with a low level of residual
deformation. The top side of this insert, in other words, the side that is normally
facing the foot, is comprised of a series of spaces that correspond to the pivots
or shock absorbers that protrude from the bottom side of the insert. These shock absorption
elements are configured in a way that when compressed by the user's weight they give
in, absorbing the shock from the foot step and consequently obtaining a sensation
of well being and comfort.
[0005] In the spaces that make up the inside part of the shock absorbing elements or pivots,
a base has been inserted which does not completely fill in the shock absorbing area
because this way, when weight is added, the outer ring of the space gives in until
it is supported on to the inner base or pivot, which provides a second and harder
shock absorption and at the same time, assists in returning the shock absorbers to
their initial position when the weight of the foot ceases to press on them thus preventing
any loss of efficiency with usage and from walking.
[0006] These inner pivots will adapt to each point on the foot they are in contact with
and in accordance with the weight they are supporting at that time, forming a type
of regulated support at the bottom of the foot in accordance with the amount of surface
contact area and weight it supports at each point.
[0007] As an advantage, the described shock absorbing insert also has the ability to circulate
air from the heel to the foot sole, as in the natural way of walking. This double
effect of the shock absorption and ventilation is produced by the same mechanism that
creates the shock absorption pivots; in other words, by their compression. This way,
when they are compressed, the air is forced out through these cavities, circulating
through the channels that inter-connect the shock absorbers, and producing an air
flow that provides a necessary sensation of comfort throughout the length and width
of the bottom of the sole.
[0008] This sensation and effect is accompanied by its combination with a translucent insole,
which in addition to the aesthetic effect provided by these shock absorbers, it has
numerous micro-orifices that cover the bottom of the sole, which enable air to escape
and re-circulate throughout the entire shoe.
[0009] Throughout the description and claims, the word "comprises" and its synonyms do not
intend to exclude other technical characteristics, additions, components or steps.

invention will in part be derived from the description and in part from placing the
invention into practice. The following examples and drawings provide an illustration
and are not intended to limit this invention. Additionally, this invention covers
all the possible combinations of particular and preferred embodiments indicated herein.

DETAILED DESCRIPTION OF THE APPLICATION METHODS
[0011] As can be observed in fig. 1 the shoe insert that is recommended in this invention
consists essentially of
a one-piece insert (1) manufactured from polymeric material with a low level of residual
deformation, soft enough so that the shock absorbing effect is achieved through compression,
but with enough quality for it to recover and not deform permanently prior to the
timeframe guaranteed by the terms of use; this insert is made of
multiple elements that provide shock absorption, which consists of numerous cavities
(2), each corresponding with the pivots or shock absorbing elements (3), which extend
out from the bottom part of the insert (fig.3);
an area where the aforementioned shock absorbing elements (2, 3) are configured so
when they are compressed by the user's weight, they give in and absorb the shock produced
by the action of stepping.
[0012] In the mentioned cavities, (2) which as indicated make up the inside of the shock
absorbing elements (3), an inner base or pivot (4) has been inserted, which does not
entirely fill the cavity area of the shock absorbing elements; (3) because this way,
the weight causes the outer ring to give in (21) until it is supported on the base
or inside pivot (4), which in turn acts as a stronger, second shock absorber, which
at the same time helps the shock absorbers to spring back to their initial position
when the weight of the foot stops exerting pressure over them and don't lose efficacy
with use or from walking.
[0013] These inner pivots (4) will adapt to each point of the foot they are in contact with
and depending on the weight they are supporting at each moment, they produce a type
of controlled support at the bottom of the foot.
[0014] In an embodiment of this invention, the insert (1) is also comprised of multiple
channels (5) joining the shock absorbing elements (2, 3, 4) which are configured to
circulate air from the heel to the sole.
1. Foot insert (1) manufactured as one-piece from polymeric material with a low level
of residual deformation, soft enough to provide shock absorption when compressed,
but of sufficient quality for it to spring back and not permanently deform,
characterized in that it comprises
a plurality shock absorbers consisting of multiple cavities (2), each corresponding
with the pivots or shock absorbing (3) elements, which extend out from the bottom
part of the insert,
and where the aforementioned shock absorbing elements (2, 3) are configured so that
when compressed by the user's weight, they give in and absorb the shock produced by
stepping.
2. An insert, in accordance with claim 1 where the cavities (2) house an inner base or
pivot (4) that does not completely fill the cavities (2) of the shock absorbing elements
(3).
3. Insert in accordance with claim 2 where the inner pivots (4) are configured to adapt
to each of the points of the foot they come in contact with and depending on the weight
they support at the time, they produce a type of controlled support at the bottom
of the foot.
4. Insert in accordance with prior claims, where the insert (1) also incorporates multiple
channels (5) that connect the shock absorbing elements (2,3,4) which are configured
to circulate air from the heel area to the sole.
5. Shoe insole characterized in that it is comprised of an insert (1) as the one described in claims 1 to 4; and a translucent
insole comprised in itself of multiple micro-orifices that cover the entire foot sole
and are configured to enable air to escape and be re-circulated.
6. Shoe that is characterized in that it is comprised of an insert as the one described in claims 1 to 4 or the insole
