  • Publication number: 20130160332
    Abstract: A high heel shoe pertains to a folding heel which folds resiliently when the heel tip contacts a surface and absorbs impact transferred from the heel of a wearer's foot to relieve fatigue while walking. The high heel shoe having a foldable heel includes: a sole (110) having a bottom portion (111) contacting the ground, and a tilt portion (112) tilted upwardly from the bottom portion (111); a heel (130) having a front top (131) hinged to the intermediate portion of the lower surface of the tilt portion (112); and a resilient member (140) of which both ends are fixed at a rear lower surface (112a) of the tilt portion (112) and at a top (132) of the heel (130), respectively. The heel (130) also has an unfolded state in which the elastic force of the resilient member (140) is released.
