Abstract

An improved foot orthotic is disclosed which includes an L-shaped boot and a sole plate which mat be mounted to the boot using a bracket disposed in a recessed arch portion of the boot. Typically, a projection extends from the sole plate into the bracket. The projection may extend into a slot and may have an enlarged head which nests in a recess in the bracket. The sole plate may be removed by withdrawing the projection from the bracket. Preferably, the bracket is recessed so that when the wearer of the orthotic walks, the bracket does not touch the walking surface. A toe plate may also be used in conjunction with the boot. The toe plate may be mounted to the bracket independently of the sole plate. In one embodiment, the toe plate includes two arms separated by a slot. The two arms embrace a portion of the bracket. Mating ribs and recesses on the bracket and toe plate arms retain the toe plate in the desired position.

Claims

1. A foot orthotic comprising:

a boot, the boot comprising a toe portion comprising a forward end, a recessed arch portion and a heel;

a sole plate removably mountable on said boot, said sole plate comprising a textured surface on a first side for engagement with a walking surface, and an upstanding projection disposed on a second side opposite of said first side;

a bracket disposed on said boot, said bracket comprising a slot for receiving said projection on said sole plate, said bracket comprising a lower wall spaced from said boot and structured to face said sole plate, said lower wall of said bracket being spaced from a line connecting the forward end of said toe portion of said boot and said heel of said boot and on a side of said line facing said arch portion; and

mating portions of a hook and loop fastener disposed on opposed, confronting surfaces of said boot and said sole plate.

2. The foot orthotic of claim 1 wherein said projection comprises an enlarged head disposed on an end thereof spaced from said sole plate, and wherein said bracket comprises a recess for nesting of said enlarged head.

3. The foot orthotic of claim 1 wherein said bracket comprises a slot surrounded by upstanding walls, and wherein said projection on said sole plate comprises an enlarged head spaced from said second side of said sole plate, said enlarged head being structured to ride along said upstanding walls of said bracket as said projection passes through said slot of said bracket.

4. The foot orthotic of claim 1 wherein said bracket is disposed in said recessed arch portion of said boot.

5. A foot orthotic comprising:

a boot, the boot comprising a toe portion comprising a forward end, a recessed arch portion and a heel;

a toe plate mountable on said bracket independently of said sole plate.

6. The foot orthotic of claim 5 wherein said toe plate comprises:

a toe pad for supporting toes; and

at least one arm insertable into said bracket at a location spaced from said sole plate for retention of said toe plate on said bracket.

7. The foot orthotic of claim 6 wherein said toe plate comprises two generally parallel arms forming a slot therebetween for embracing a portion of said bracket.

8. The foot orthotic of claim 7 further comprising mating ribs and ridges disposed on opposed, interlocking surfaces of said bracket and said arms of said toe plate.

9. In combination:

a boot having a generally L-shaped configuration and comprising a toe portion, a heel, a concave arch portion and a leg portion;

a sole plate removably attached to said boot and extending generally from the heel to the toe portion of the boot, said sole plate comprising an upstanding projection disposed on an upper surface thereof facing said boot;
