Abstract
An athletic training shoe insert includes particles of heavy material mixed with a flexible porous material and molded into an insole form to fit within a shoe. The particles and the insole form are designed to allow a human foot to be placed comfortably in the shoe and cooperate to substantially increase the weight of the shoe for training purposes. The amount of particles is changeable to change the weight of the athletic shoe. That is, a larger amount of particles can be added to increase the weight of the shoe. Also, additional insoles of particles and flexible porous material can be added to a shoe to substantially increase the weight if desired.
Claims15
An athletic training shoe insert comprising:
- particles of carbonyl iron;
- a flexible porous insert form constructed to fit within the athletic shoe and to receive the particles of carbonyl iron and hold the particles of carbonyl iron in a fixed position within the athletic shoe;
- and
- the particles of carbonyl iron and the insert form being designed to allow a human foot to be placed comfortably in the athletic shoe and to cooperate to substantially increase the weight of the athletic shoe for training purposes.
An athletic training shoe insert comprising:
- particles of carbonyl iron;
- flexible porous material;
- a flexible porous insert form including the particles of carbonyl iron and the flexible porous material intermixed and molded so as to fit within an athletic shoe in a fixed position with the particles of carbonyl iron dispersed throughout the flexible porous insert form;
- and
- the flexible porous insert form being designed to mold to a human foot and to substantially increase the weight of the athletic shoe for training purposes.
A method of fabricating an athletic training shoe insert comprising the steps of:
- providing particles of carbonyl iron;
- providing flexible porous material;
- and
- molding the particles of carbonyl iron and flexible porous material into a flexible porous insert form designed to fit within an athletic shoe in a fixed position, the flexible porous insert form being designed to mold to a human foot and to substantially increase the weight of the athletic shoe for training purposes.
