Abstract: This invention relates to folding shoes made with the use of shape-memory resins at least in their instep or, where a shaft is present, at least in their instep and shaft and transformable by folding into a given shape or restorable from the folded shape to the memorized shape by heating at a temperature above the glass transition temperature and below the melting temperature of said shape-memory resins and to a process for manufacturing said folding shoes. The folding shoes of this invention are of practical value as they can be restored to the memorized shape at the time of use, can be conveniently stored away or carried about in the fixed folded shape of reduced volume while not in use, and can be manufactured readily by the process of this invention.
