Abstract
Abstract Disclosed here is a novelly designed sandal whose vamp or sole can be changed. If there are many so designed vamps and soles, then many times new sandals can be composed by the interchange among the vamps and soles. For example, 5 different pairs of vamps and 2 different pairs of soles, then 10 different pairs of sandals can be made. The sandal can also be further changed by changing the binding, welt or side element with different color, type, etc.
