SHOE INSERT
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
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.
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
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.

CA 02760351 2011-10-27
2
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.
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.
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.
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.

synonyms do not intend to exclude other technical characteristics, additions,
components or steps. For experts in the field, other objectives, advantages

particular and
preferred embodiments indicated herein.
BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE APPLICATION METHODS
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.

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.
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.
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.
