MODULAR INSOLE SYSTEM

Abstract

The modular insole system includes a base pad with a plurality forms releasably connected to the top surface thereof. The forms respectively correspond to orthotic support for the heel, arch, and ball portions of a foot. The forms are preferably releasably connected by hook and loop fastening material to the base pad and are made of foam. The forms are adjustable in any location on the top surface of the base pad to provide a custom configuration for a given user. The base pad and foam forms can be provided in different sizes, foam types, durometer hardness, and the like, and can be mixed and matched as needed to further customize the modular insole system for the given user. The forms have edges that complement each other so the insole can more closely simulate expensive custom insoles that are monolithic even when moved about on the base pad.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0041] The new and unique modular insole system of the present invention is shown and described herein in detail.

[0042] It should be understood that the modular insole system 10 is provided for both feet, namely, for both the right and the left foot, which are merely mirror images of each other and function identically to each other. Thus, a pair of modular insole systems 10 are provided for both feet, as shown in FIG. 9. For ease of discussion and illustration herein, the present invention will be discussed in detail regarding a modular insole system 10 for one foot, such as the right foot, but it should be understood that the present invention includes a modular insole system 10 for the left foot as well.

[0043] Turning now to FIGS. 1-8, various view of the modular insole system is shown. FIG. 9 shows the modular insole system for use for both feet. FIGS. 1-8 shows a base pad, generally referred to as 14, with a number of preferably foam forms 16a-16c for different parts of the foot, such as the heel, arch, and ball, that attach to a top surface 14a of the base pad 14. As shown in FIG. 10, indicia 18 is preferably provided on the top surface 14a of the base pad 14 to help guide user placement and adjustability for location of the foam forms, 16a-16c both front/back and side/side, on the base. For example, the indicia 18 can be provided to help locate the forms 16a-16c for the specific locations of heel, arch and ball of the foot of a user.

[0044] As seen in FIG. 14, the base pad 14 is preferably a flat, semi-rigid pad shaped to cover the inside bottom surface of a shoe 12. Insoles are so well known in the art that further details need not be provided. The modular insole system 10 of the present invention is shown installed in a shoe 12 in FIG. 18. The base pad 14 includes loop material portion 20 of fastening material that is permanently bonded to the top face 14a of the base pad 14. The foam forms 16a-16c are each shaped to support one of the three primary areas of the foot, namely, the heel, arch, and ball. The upward facing side of each foam form 16a-16c is contoured to interface with the underside of a respective one of the three primary areas of the foot. The downward facing side of each foam form 16a-16c is preferably flat and permanently bonded to hook material 22 of the hook and loop fastener structure. As discussed below in connection with FIGS. 11 and 15-17, the hook material 22 is preferably recessed in a seat 24.

[0045] Therefore, the present invention addresses the three fundamental stress areas on the foot: (1) the heel when landing, (2) the ball when launching, and (3) the arch which is the bridge between them. The fully customizable and adjustable insole 10 of the present invention uses hook material 22 and loop material 20 to adjust and configure the foam forms 16a-16c on the base pad 14. The foam forms 16a-16c can be offered in different sizes and durometers (degrees of firmness) and can be of any type of cushioning material that can be re-configured at any time and on demand. Therefore, the insole 10 of the present invention, typically provided in pairs of insoles 10, one for each foot, are uniquely inter-changeable and re-adjustable because the foam forms 16a-16c supporting the heel, arch, and ball of the foot can be easily detach and re-attached by the user whenever desired. Re-adjustments are possible along two axes in a plane parallel to the top surface 14a of the base pad 14, namely, front to back and side to side.

[0046] Once a modular insole 10, namely a pair of insoles 10, is assembled and configured in accordance with the modular insole system 10 of the present invention, it can then be inserted into a shoe 12 or other footwear for use by the user. For example, the insole 10 of the present invention can be placed on the top of a midsole (not shown) already residing on an outsole of the footwear 12. Alternatively, a shoe midsole (not shown) can be removed and the modular insole 10 of the present invention can be placed directly on the outsole of the footwear 12. Or, while not typical, the modular insole 10 of the present invention may be placed on an existing insole in the footwear 12. In other words, the insole 10 of the present invention may be incorporated into existing footwear 12 in many different ways and still be within the scope of the present invention. Such configuration and use of the modular insole 10 of the present invention can be modified by the user to suit their particular footwear needs and need not be discussed in further detail as such footwear construction is known in the art.

[0047] FIG. 12 shows examples of how the modular insole system 10 can include forms 16a-16c that have different characteristics, such as size, foam type, configuration, shape firmness, durometer hardness, finish, material type, and the like. Thus, the consumer can choose foam forms 16a-16c from an array of different characteristics based on their individual needs and preferences. It is thus also possible to mix and match forms 16a-16c of different characteristics. For example, an individual may desire a very hard arch form 16b, a medium hardness heel 16c form but a very soft form at the ball of the foot 16a. This is possible with the present invention. Moreover, color and part numbers can be used to easily identify specific segments to facilitate use of the modular insole system 10 of the present invention for the user. As in FIG. 12, the lower set of forms 16a-16c, generally referred to as 26 may be of a harder material while the upper set 28 may be of a softer material. As mentioned above, these forms 16a-16c may be mixed and matched, as desired.

[0048] For example, in consideration of arch support, one consumer may prefer a large size with medium firmness and a high arch, while another may prefer a medium size with rigid firmness and a low arch. Thus, for each of the primary areas of the foot, the consumer may customize the size and firmness of each foam form 16a-16c supporting each area of the foot.

[0049] The perimeter of each foam form 16a-16c is minimized or tapered to reduce contiguity and maximize range of movement. The foam forms 16a-16c are movable along two axes: front to back and side to side, as shown by the double arrows on each form 16a-16c in FIG. 7. Still referring to FIG. 7, the plan shape of the foam forms 16a-16c are configured so they complement each other. More specifically, the interfacing edges 30a-30c of each foam form 16a-16c are configured so they have a shape that is complementary to the shape of a neighboring foam form. For example, the edge 30a of foam form 16a has a wave-like shape to substantially match the rounded shape of the edge 30b of the arch foam form 16b. Similarly, edge 30c of foam form 16c is wave like edge to substantially match with the edge of 30b of the arch foam form 16b. This a particularly advantageous because it enables the insole 10 of the present invention to more closely simulate an expensive custom insole that is monolithic. Also, these complementary shapes of edges 30a-30c of the forms 16a-16c permit up and down and side to side adjustment of the forms 16a-16c while still closely simulating monolithic insole.

[0050] Referring now to FIG. 11, a cross-sectional view through the line 11-11 of FIG. 7, shows further details of one of the forms 16a-16c employed in the present invention, namely, the arch foam form 16b, as an example. The other forms 16a, 16c and their releasable attachment to the base pad 14 with loop material 20 thereon would have a similar cross-section. The bottom sides of all forms 16a-16c are shown in FIGS. 15-17. Referring to FIGS. 11 and 15-17, it can be seen that each foam form 16a-16c preferably includes a recessed seat 24 in the bottom surface thereof. Thus, the hook material is preferably inset or recessed in the underside of each foam form 16a-16c, which can help enhance a flush fit between the forms 16a-16c and base pad 14 and thereby allow the insole to feel “seamless” to the user's foot. It is also more aesthetically appealing. Alternatively, it is possible that the hook material 22 is secured directly on the bottom surface of the forms 16a-16c.

[0051] In view of the above, the modular insole system 10 provides consumers with a moderately priced, fully customizable, and continuously re-adjustable and re-configurable insoles 10 which provide ideal support and comfort. Thus, the consumer can easily re-configure the insole 10 at any time with respect to the position, size, and firmness of each foam form 16a-16c supporting each of the three primary areas of the foot. To achieve ideal support and comfort, any foam form 16a-16c may be re-positioned at any time, and any foam form 16a-16c may be removed and replaced at any time with a different size or firmness.

[0052] While there is shown and described herein certain specific structure embodying the invention, it will be manifest to those skilled in the art that various modifications and rearrangements of the parts may be made without departing from the spirit and scope of the underlying inventive concept and that the same is not limited to the particular forms herein shown and described except insofar as indicated by the scope of the appended claims.
