Abstract: Size-adjustable footwear includes an outer shell and a liner disposed within the shell. The liner has an upper, a heel, and a toe. An insert is releasably receivable within the toe of the liner. The liner has a first size which is defined between the heel and the insert when the insert is received within the toe, and a second size which is defined between the heel and the toe when the insert is not received within the toe. The first size is less than the second size. A user may select footwear based on the smaller first size, and then as his or her feet grow, remove the insert to accommodate the larger feet.
