Abstract
A variable weight athletic shoe is described. The athletic shoe may be removably fitted with training weights of varying heaviness or the weights may be left off entirely without damaging the aesthetic appeal or functional aspects of the shoe. Weights of various sizes are quickly and securely coupled to the rear portion of the heel-enclosing section of the shoe with several types of attachment clips and latches. In other variants of the invention, shoe weights are removably attached within cavities in the heel or arch sections of the shoe sole. Weights may also be attached across the instep of the athletic shoe. The shoe weights may be covered in various protective and decorative coverings and may contain lightening holes to achieve the desired weight in a given size.
