Abstract
Abstract A shoe upper easily connected by a connecting device to a lower member or mid sole having a lattice structure. The shoe also includes additional connecting devices to releasably connect the heel to the mid sole and upper. The outer sole is connected to the mid sole by glue or double-sided tape. The mid sole is made from a synthetic material which allows breathing through the apertures in the lattice structure. Also, the outer sole and heel are removeably attached to the mid sole and upper to provide a shoe that may be resoled and reheeled inexpensively using ordinary tools.
