Abstract

Exercise shoe assemblies include a shoe body, at least one support bracket integrated into the shoe body, and a resistance device connected to the support bracket. The resistance device preferably includes a flexible member, and may include a housing from which the flexible member is extracted.

Claims

1. An exercise shoe assembly, comprising:

a shoe body;

at least one support bracket integrated into the shoe body, wherein the at least one support bracket is configured to define a downwardly opening hook; and

a resistance device connected to the support bracket, wherein the resistance device includes a flexible member, and the resistance device is secured beneath the hook in a manner that accommodates upward pulling action on the flexible member.

2. The exercise shoe assembly of claim 1, wherein the resistance device includes a housing, a sheave rotatably mounted inside the housing, and a rewind spring interconnected between the sheave and the housing, wherein the flexible member is wound about the sheave.

3. The exercise shoe assembly of claim 2, wherein the housing is configured to straddle the support bracket.

4. The exercise shoe assembly of claim 2, wherein the support bracket is configured to straddle the housing.

5. The exercise shoe assembly of claim 1, further comprising a removable bracket_interconnected between the support bracket and the resistance device, wherein the removable bracket is releasably latched to the support bracket.

6. The exercise shoe assembly of claim 5, wherein the resistance device is sandwiched between the removable bracket and a portion of the shoe body.

7. The exercise shoe assembly of claim 2, wherein the housing defines an outermost shell that shrouds all sides of the sheave, and the shell_is sized and configured to be held in a person'"'"'s hand when removed from the shoe.

8. The exercise shoe assembly of claim 5, further comprising a latch movably connected to the support bracket and operable to secure the removable bracket in at least one desired position relative to the support bracket.

9. The exercise shoe assembly of claim 5, wherein the shoe body defines a downwardly opening channel sized and configured to slidably receive a portion of the removable bracket, and the latch includes a key member that cooperates with an opening in the removable bracket to retain the removable bracket in the desired position when occupying a first orientation relative to the shoe body, and to release the removable bracket for movement from the desired position when occupying a discrete, second orientation relative to the shoe body.

10. The exercise shoe assembly of claim 8, wherein a portion of the support bracket is configured to occupy an opening in the removable bracket when the removable bracket occupies the desired position, and the latch is rotatable from a first orientation that accommodates movement of the removable bracket onto said portion, to a second orientation that blocks removal of the removable bracket from said portion.

11. The exercise shoe assembly of claim 8, wherein the latch movably secures the removable bracket in one said desired position forward of the shoe body, and alternatively secures the removable bracket in another said desired position to one side of the shoe body.

12. An exercise shoe assembly, comprising:

a shoe body;

at least one support bracket integrated into the shoe body; and

a resistance device connected to the at least one support bracket, wherein the at least one support bracket accommodates the resistance device in at least two operatively discrete positions relative to the shoe body, wherein one of the positions is forward of the shoe body, and another of the positions is to one side of the shoe body.

13. The exercise shoe assembly of claim 12, wherein the resistance device includes a housing, a sheave rotatably mounted inside the housing, a flexible member wrapped around the sheave and having a distal end that is pulled from the housing during exercise, and a rewind spring interconnected between the sheave and the housing in a manner that biases the distal end of the flexible member toward the housing.

14. The exercise shoe assembly of claim 13, wherein the resistance device further includes a brake drum rotatably mounted inside the housing and linked to the sheave in a manner that resists unwinding of the flexible member from the sheave without resisting rewinding of the flexible member onto the sheave.

21. The exercise shoe assembly of claim 12, wherein an intermediate bracket is interconnected between the at least one support bracket and the resistance device, and the intermediate bracket is selectively repositionable relative to the shoe body between a first orientation, supporting the resistance device in one of said desired locations, and a second orientation, supporting the resistance device in a another of said desired locations.

15. An exercise shoe assembly, comprising:

a shoe body that defines a foot-shaped planform;

a support bracket integrated into the shoe body; and

a resistance device connected to the support bracket, wherein one of the resistance device and the support bracket includes a portion disposed outboard from the planform, and the resistance device includes a flexible member that is pulled from a location defined by said portion.

16. The exercise shoe assembly of claim 15, wherein the planform includes a forwardmost toe portion, and said location is disposed a distance forward of the forwardmost toe portion.

17. The exercise shoe assembly of claim 15, wherein the planform includes an outermost sidewall, and said location is disposed a lateral distance apart from the outermost sidewall.

18. The exercise shoe assembly of claim 15, wherein an intermediate bracket is interconnected between the support bracket and the resistance device, and the intermediate bracket is selectively repositionable between a first orientation, extending lengthwise relative to the shoe body, and a second orientation, extending widthwise relative to the shoe body.

19. The exercise shoe assembly of claim 15, wherein the resistance device includes a housing, and said portion is a guide rotatably mounted on the housing.

20. The exercise shoe assembly of claim 19, wherein the resistance device further includes a sheave rotatably mounted inside the housing and a rewind spring interconnected between the sheave and the housing, and the flexible member is wrapped around the sheave and has a distal end that is pulled from the housing during exercise, subject to resistance imparted by the rewind spring.
