## Abstract

A canine trail boot has a molded sole with raised lugs that divide the sole into individual pad cups that each receive a single pad from a dog foot. Independent movement between adjacent pad cups better replicates a dog's pad movement. The molded sole may include a toe having unidirectional treads, a tail having a combination of treads that also receive and retain straps, and a cushioning pad that protrudes into and engages with an indentation on a dog's paw to retain a boot securely. The sole interior may be layered with insoles that provide puncture resistance, heat isolation or reflection, and other custom interior features, or a liner may be provided that may also further incorporate the raised cushioning pad. The cushioning pad may be longitudinally adjustable within the boot interior, to tailor the cushioning pad to the ideal position to engage with a dog's metatarsal or metacarpal pad.

## Claims

### Claim 1

A canine trail boot, comprising:
a boot top;
a sole coupled to said boot top to define a paw receiving space there between, wherein said sole further comprises:
a toe rising from said paw receiving space and having a plurality of unidirectional treads;
a tail rising from said paw receiving space; and
said sole having five pad cups including four digital pad cups and a fifth metatarsal metacarpal pad cup;
each of said five pad cups having a cup base exterior surface that is configured to be in ground contact and an interior surface that is configured to be in contact with a dog's pad, a cup sidewall that rises vertically from said cup base and configured to be substantially out of contact with a flat ground surface and spaced in a portion adjacent to said ground surface by a void from a vertically rising side wall of an adjacent one of said five pad cups, and a flexible lug coupling said cup sidewall to said adjacent one of said five pad cups in a portion of the cup side wall distal to said cup base.

### Claim 2 (depends on 1)

The canine trail boot of claim 1, said flexible lug is configured to be sufficiently pliable to permit each pad cup to move both up and down and side to side through at least a functional range effective to mimic independent pad motion in a dog that is relatively uninhibited by adjacent pad cups.

### Claim 3 (depends on 2)

The canine trail boot of claim 2, wherein said flexible lug further comprises a sheet geometry.

### Claim 4 (depends on 2)

The canine trail boot of claim 2, wherein each of said five pad cups are configured to receive a one of a dog's pads therein and said flexible lug is configured to separate each of said five pad cups and configured to allow flexure in said flexible lug to permit relative motion between each of said five pad cups during movement of said dog.

### Claim 5 (depends on 2)

The canine trail boot of claim 2, wherein said sole further comprises:
said toe rising from a leading edge of said paw receiving space; and said tail rising from a trailing edge of said paw receiving space.

### Claim 6 (depends on 1)

The canine trail boot of claim 1, further comprising:
a mid-base having an exterior configured for ground contact during locomotion, a leading portion that leads a trailing portion and which is distal on said mid-base relative to said trailing portion.

### Claim 7 (depends on 1)

The canine trail boot of claim 1, wherein said flexible lug further comprises a generally planar sheet material.

### Claim 8 (depends on 1)

The canine trail boot of claim 1, wherein said tail further comprises an omnidirectional tread.

### Claim 9 (depends on 1)

The canine trail boot of claim 1, wherein said tail further comprises a pair of generally linear treads spaced from each other and configured to engage with a ground surface, and further configured to receive and retain a tensioned strap there between.

### Claim 10 (depends on 1)

The canine trail boot of claim 1, wherein said toe unidirectional treads further comprise a right triangular prism geometry.

### Claim 11 (depends on 1)

The canine trail boot of claim 1, wherein said toe unidirectional treads further comprise segmented treads.
