An athletic training shoe insert includes one or more thin strips of heavy material, such as lead, constructed to fit within a shoe and formed to be spaced apart along the length of the shoe and to extend the width of the shoe. A removable insole is constructed to fit within the shoe and to hold the thin strips in a fixed position within the shoe. The thin strips and the insole 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 number of thin strips is changeable and the position of the thin strips along the length of the athletic shoe is changeable to change the weight of the athletic shoe. That is, a larger number of thin strips can be added to increase the weight of the shoe. Also, additional insoles and weights can be added to a shoe to substantially increase the weight if desired. |
