• an expanding portion comprising an upper portion having at least one of a tongue, eyelets, laces, and hook and loop fasteners, and a midsole plate securedly, permanently coupled to the upper portion;
• a plurality of sole portions, wherein at least one sole portion of the plurality of sole portions is a different size than a second sole portion of the plurality of sole portions;
• and
• a plurality of locking mechanisms, wherein at least two of the plurality of locking mechanisms are securedly, permanently coupled to each sole portion of the plurality of sole portions, wherein the plurality of locking mechanisms comprises a plurality of studs, and wherein at least two studs of the plurality of studs protrude upwards from an upper surface of a sole portion of the plurality of sole portions;
• wherein each of the plurality of studs is selectively attachable to the expanding portion to securely join a sole portion of the plurality of sole portions to the expanding portion at a desired shoe size, wherein the midsole plate is selectively, releasably attachable to a sole portion of the plurality of sole portions, wherein at least one sole attachment bore is defined in a lower surface of the midsole plate, wherein the sole attachment bore is configured to receive a portion of a stud of the plurality of studs therein to couple the midsole plate to the stud, wherein the at least one sole attachment bore comprises a plurality of sole attachment bores such that engagement between at least two sole attachment bores of the plurality of sole attachment bores and the at least two of the plurality of studs expands the midsole plate and the upper portion to a desired size, wherein engagement between the at least two sole attachment bores and the at least two of the plurality of studs selectively, releasably attaches the midsole plate to a sole portion of the plurality of sole portions.
