## Abstract

A reusable, customizable shoe-insole having an encased viscoelastic material disposed on base of an insole and configured to assume an arch support structure in accordance with sole geometries of each additional user.

## Claims

### Claim 1

A custom, reusable shoe insole comprising:
a viscoelastic material disposed on a polymeric insole such that weight of each of a plurality of users shapes the viscoelastic material into a customized arch support structure bound in part by a heel bone and at least one metatarsal head of each of the users.

### Claim 2 (depends on 1)

The custom reusable shoe insole of claim 1, wherein the viscoelastic material is disclosed inside an airtight polymeric encasement.

### Claim 3 (depends on 2)

The custom reusable shoe insole of claim 2, wherein the viscoelastic material has a mass of about 30 to 40 grams.

### Claim 4 (depends on 2)

The custom reusable shoe insole of claim 2, wherein the viscoelastic material includes malleable clay.

### Claim 5 (depends on 4)

The custom reusable shoe insole of claim 4, wherein the viscoelastic material includes polydimethylsiloxane.

### Claim 6 (depends on 2)

The custom reusable shoe insole of claim 2, wherein the polymeric encasement is constructed from a polymer selected from the group consisting of polyvinyl chloride, polypropylene, and polyethylene.

### Claim 7 (depends on 2)

The custom reusable shoe insole of claim 2, wherein the polymeric encasement has an arcuate boundary.

### Claim 8 (depends on 2)

The custom reusable shoe insole of claim 2, further comprising a padding layer covering the encasement.

### Claim 9

A method of constructing a custom, reusable shoe insole, the method comprising:
providing a polymeric insole base; and
placing a viscoelastic material on the insole base so as to enable the viscoelastic material to assume a first customized arch support structure of a first user stepping on the viscoelastic material and assume a second customized arch support structure of a second user stepping on the first customized arch support structure.

### Claim 10 (depends on 9)

The method of claim 9, wherein each of the first customized arch support structure and the second customized arch support structure is bound in part by a heel bone and at least one metatarsal head.

### Claim 11 (depends on 9)

The method of claim 9, wherein the viscoelastic material is disclosed inside an airtight polymeric encasement.

### Claim 12 (depends on 11)

The method of claim 11, wherein the viscoelastic material has a mass of about 30 to 40 grams.

### Claim 13 (depends on 11)

The method of claim 11, wherein the viscoelastic material includes malleable putty.

### Claim 14 (depends on 13)

The custom reusable shoe insole of claim 13, wherein the viscoelastic material includes polydimethylsiloxane.

### Claim 15 (depends on 11)

The custom reusable shoe insole of claim 11, wherein the polymeric encasement is constructed from a polymer selected from the group consisting of polyvinyl chloride, polypropylene, and polyethylene.

### Claim 16 (depends on 11)

The custom reusable shoe insole of claim 11, wherein the polymeric encasement has an arcuate boundary.

### Claim 17 (depends on 11)

The custom reusable shoe insole of claim 11, further comprising a padding layer covering the encasement.

### Claim 18 (depends on 17)

The custom reusable shoe insole of claim 17, wherein the padding layer includes slow rebound foam.
