Abstract: A shoe has a sole with a toe, heel and arch. A two part heel has a low heel block attached to the sole heel and includes a slot therein. A high heel extension is attached to the low heel block through a support beam having a substantially rectangular cross-section capable of limited axial and pivotal movement. The fit between the beam and the slot prevents rotational movement of the high heel about its axis. The high heel extension can be pivoted between a first position where it underlies the low heel block and a second position where it lies beneath the sole arch. The bottom of the low heel block has a heel lift extending downwardly engaging the ground when the high heel is stowed. This low heel lift is enclosed by a beveled edge at the top of the high heel piece when it is vertical.

Abstract: 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.
