Abstract

Abstract A soft pad to be worn inside the shoe of a person having a cancaneal spur or bony projection downward from the os calcis, or a calcium deposit in the same area. The essential parts of the pad include a pad of soft and relatively compressible fabric, e.g., felt, having a hole therethrough to receive the spur. This hole is filled with an insert of resilient foam rubber which is compressed by the spur, and which assumes its original shape when the user removes his shoe. To make the pad more durable, a lower layer of soft or imitation leather is disposed beneath the felt pad, and an upper layer of leather may also be added, the upper layer having a hole therethrough which registers with the hole through the thickness of the felt pad. When both leather layers are used, they are preferably made wider and longer than the felt pad, and they are disposed to extend beyond the periphery of the felt pad in all directions. The leather layers may then be bonded together by stitching or adhesives, and they thus encase and protect the layer of felt. It is not necessary to bond the assembled pad to the user''s shoe; in fact, it is an advantage to be able to move the pad from one pair of shoes to another.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 48 words
A cushion pad for heel spurs comprising a layer of soft and compressed fabric, said layer having an opening through the thickness thereof and being contoured to fit inside the user''s shoe in the heel area thereof, and an insert in said hole of soft and resilient material.
Claim 2
Dependent Claim 48 words
A cushion pad for heel spurs comprising a layer of soft and compressed fabric, said layer having an opening through the thickness thereof and being contoured to fit inside the user''s shoe in the heel area thereof, and an insert in said hole of soft and resilient material.
Claim 3
Dependent Claim 40 words
The cushion pad of claim 1 which also includes a lower covering of relatively hard but pliable material underlying said layer of fabric and said resilient insert, said lower covering being bonded to said fabric and insert by an adhesive.
Claim 4
Dependent Claim 43 words
The cushion pad of claim 2 which further includes an upper covering of relatively hard but pliable material disposed on top of said fabric and resilient insert, said upper covering having an opening therethrough registering with the opening in said layer of fabric.
Claim 5
Dependent Claim 28 words
The cushion pad of claim 3 in which said upper and lower coverings extend beyond the periphery of the layer of fabric and are bonded to one another.
Claim 6
Dependent Claim 24 words
The cushion pad of claim 1 in which said fabric layer is a layer of felt and said resilient insert is a foam rubber.
Claim 7
Dependent Claim 59 words
The cushion pad of claim 5 which further includes both a lower covering of relatively hard but pliable material underlying said layer of felt and insert and an upper covering of similar material disposed on top of said layer of felt and insert, such upper covering having a hole therethrough which registers with the hole in the felt pad.
Claim 8
Dependent Claim 34 words
The cushion pad of claim 6 in which said coverings are thin layers of leather which extend beyond the periphery of said layer of felt and are bonded to one another at their edges.
Claim 9
Dependent Claim 53 words
The cushion pad of claim 6 in which said holes in the felt pad and upper covering are disposed to be centered under the center of the heel bone when the adjacent end of the pad fits against the curved back of the shoe, and said holes are approximately 1 inch in diameter.
Claim 10
Dependent Claim 31 words
The cushion pad of claim 8 in which the centers of said holes are approximately 1 1/2 inches from the rearward end of the pad, measured along its longitudinal center line.
Claim 11
Dependent Claim 27 words
The cushion pad of claim 1 in which said layer of soft and compressed fabric has an approximate thickness in the range of 1/8 to 1/2 inch.
