## Abstract

Systems and methods for customizable footwear inserts having a plurality of removable sections. Removable sections may be permanently bonded to adjacent layers of the inserts to eliminate or minimize the tendency of removable sections surrounding the removed sections to fall out or migrate into the cavity created by the removed sections. In some aspects, multiple layers are provided to increase the comfort, support, and/or fit provided to the wearer of the insert. Further, some embodiments include a removable backing that, when removed, exposes an adhesive that may be utilized to, inter alia, adhere an original insole of footwear to the top of the footwear insert such that the user's foot is still in contact with the original insole when wearing the footwear.

## Claims

### Claim 1

A footwear insert comprising:
a fabric layer;
a first foam layer permanently bonded to an entirety of one surface of the fabric layer; and
a second foam layer permanently bonded to an entirety of another surface of the fabric layer opposite the one surface, the fabric layer and the first and second foam layers being arranged to form an insole, the first foam layer having a plurality of cuts extending from a first portion on an outer surface of the first foam layer toward the fabric layer, through a majority of the first foam layer to a second portion in the first foam layer, and terminating prior to a third portion in the first foam layer, to define an array of a plurality of adjacent removable sections, each removable section being configured to be selectively permanently removed by tearing the first foam layer such that when torn, at least a part of the third portion of the first foam layer remains permanently bonded to the fabric layer, thus covering the fabric layer to form a customized insole to reduce plantar pressures on targeted areas of a foot.

### Claim 2 (depends on 1)

The footwear insert of claim 1, wherein some of the plurality of removable sections define a perimeter of the insole.

### Claim 3 (depends on 1)

The footwear insert of claim 1, wherein the first foam layer permanently bonded to the one surface of the fabric layer is permanently bonded by an adhesive.

### Claim 4 (depends on 1)

The footwear insert of claim 1, wherein the removable sections have a square shape.

### Claim 5 (depends on 1)

The footwear insert of claim 1, wherein the second foam layer includes one or more foam sublayers.

### Claim 6 (depends on 1)

The footwear insert of claim 1, further comprising an additional layer, wherein the second foam layer is between the fabric layer and the additional layer.

### Claim 7 (depends on 6)

The footwear insert of claim 6, wherein the additional layer is fabric.

### Claim 8 (depends on 6)

The footwear insert of claim 6, wherein the additional layer is microfiber.
