A shoe (10) which has a sole (12) with a toe portion (14), a heel portion (16) and an arch portion (18) located between them. A two part heel (20) which has a low heel block (22) attached to the heel portion of the sole and includes a slot (42) formed therein. A high heel extension piece (24) is attached to the low heel block through a support beam (38) having a substantially rectangular cross-section. The support beam (38) is capable of limited axial and pivotal movement within slot. The dimensions of the support beam (38) and the slot (42) prevent rotational movement of the high heel extension piece (24) about its central axis. The high heel extension piece (24) can be pivoted relative to the sole (12) between a first position wherein it underlies and is in alignment with the low heel block (22) and a second position wherein it lies substantially beneath the arch portion (18) of said sole. The bottom of the low heel block has a low heel lift (28) that extends downwardly and engages the ground when the high heel extension piece (24) is stowed. This low heel lift (28) is completely enclosed and hidden by a beveled edge (32) at the top of the high heel extension piece (24) when it is in its vertical position high heel. A detent in the form of a spring biased ball (74) incorporated within a rotatable slotted pivot (52) and a depression (78) in the support beam (38) maintain the high heel extension piece (24) in the desired position.

L'invention porte sur une chaussure (10) comportant une semelle (12) présentant une pointe (14) un talon (16) et une partie centrale (18) les reliant. Le talon (20) est en deux parties: un bloc de talon bas (22) fixé à la semelle et présentant une fente (42); et une extension (24) formant un talon haut et reliée au bloc de talon bas (22) par une tige (38) de section sensiblement rectangulaire et à possibilités limités de déplacements axial et de pivotement, dans la fente. Les dimensions de la tige (38) et de la fente (42) empêchent la rotation de l'extension (24) autour de son axe central. Mais l'extension (24) peut pivoter par rapport à la semelle (12) entre une première position sous le bloc (22) qu'elle prolonge, et une deuxième position, où elle se trouve sensiblement sous la partie centrale (18) de la semelle. La base du bloc (22) comporte une hausse (28) le prolongeant vers le bas et en contact avec le sol quand l'extension (24) est repliée. Cette hausse (28) est entièrement entourée et cachée par le bord (32) supérieur biseauté de l'extension (24) en position verticale. Un cliquet sous forme de bille à ressort placé dans un élément pivotant (52) à fente, associé à une encoche (78) pratiqué dans la tige (38) permettent de maintenir l'extension dans la position voulue.
