"Coupling device for use in a separable coupling of the vamp of a shoe with the sole of a shoe, shoe soles, method for the manufacture of a groove for fixity on the bottom of a SAPAct and to receive a bushing for insertion in the same removu00ecvel for attaching a detachable vamp shoe soles.To enable a user mount and dismount the shoe at its pleasure; and method for the manufacture of a shoe. It is a shoe of the type slipper or sandal, which has two or more coupling devices, to highlight the part of the vamp of the shoe sole mould.The coupling devices are distributed around the edges of the vamp of the shoe and have teeth like projections which engranzam with lingu00b3etas resilient.Positioned within slots which are set on the bottom.The buttons are provided in the side walls of the sole to release the projections from the sockets, if you want to change the uppers of shoes soles.Methods of manufacture are provided for molding the sole and prevent the leakage of plastic injected within the joints that would interfere with the operation of the coupling device.The groove can be manufactured with a membrane that seals the hole of the frangu00edvel button, with a lid that fits and contains the whole groove.
