Abstract: A system and method for effecting modular investment position calculation is disclosed. The system and method comprise a data architecture having multiple stored calculation components. The calculation components include base calculation components and variant calculation components. A calculation spine is assembled by a master control module based upon information received by the master control module indicating that a variant version of a base calculation is to be performed. The calculation spine includes at least some of the base calculation components and at least one of the variant calculation components. The calculation spine is executable by the at least one programmable processor using data received by the processor such that, when the calculation spine is executed, the variant version of the base calculation will be performed using the data.

Abstract: An athletic training shoe weighted insert including a metallic powder filled thermoplastic elastomer is formed. A method of manufacturing the athletic training shoe weighted insert with a desired softness or durometer and a desired specific gravity includes the steps of selecting a metallic powder filler, with a desired specific gravity, and a thermoplastic elastomer, and a plasticizer that will produce the desired softness of the weighted insert. The method includes a compounding step of combining the thermoplastic elastomer, metallic powder and plasticizer into a pelletized compound with a desired quantity or percentage of the metallic powder filler to bring the specific gravity to the desired level and to achieve the desired softness. In a preferred embodiment the pelletized compound is then formed into the finished insert by use of the plastic injection molding process.

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.

Abstract: 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.
