integrates a slot within its sole structure, as this footwear is
assembled, and within the slot is a continuous band, that may form
part of the shoe vamp, strapping, or related structure, and which
vamp or band may be turned, for displaying different coloration or
designs, texture, or means for providing support, massaging, or
stimulation, of the foot, as through interiorly protruding tips, or
to form and dispose apertures that furnish ventilation and aeration
to the foot thereunder, all in order to change the aesthetics of
the footwear at the desire of the user. In addition, to add to the
structural integrity of the constructed shoes, a part of the vamp
or its strapping, may extend upwardly, and have a loop formed
therein, or even loop back on itself, and which may embrace the
upper part of the changeable vamp, to facilitate its retention, and

34 wherein fastener 40 comprises post 42 and transverse nub 44 that
matingly engages toe piece 32 with sole 16 having bottom 18 and top
20 with top 20 having aperture 22 and lip 24 for securing the toe
piece to the shoe.
[0073] Referring to FIG. 10, shown is an illustrative view of the
present invention in use. The present invention 10 is a shoe having
a swappable toe piece 32 attachable to sole 16 and upper 26,28 with
the sole 16 having a bottom side 18 and top side 20. Within the
body of the sole 16 is aperture 22 forming a bore having a lip 24
therein for retaining toe piece fastener 40. Toe piece 32 has
adjacent fasteners 34 for securing the toe piece to sole 16 and
upper 26, 28. Extending from the base of the toe piece is fastener
40 comprising post 42 and nub 44 for lockingly engaging the toe
piece 32 to sole 16. The toe piece also provides for an adjacent
fastener 34 comprising toe piece 32 having toe piece lip 36
incorporating rail 38 that matingly engages with upper channel 30
