A convertible shoe may include a sole portion and a plurality of interchangeable heel portions, each selectively attachable to the sole portion. The heel portions may each include a mounting surface configured to interface with a heel receiver of the sole, such that mounting the heel causes a support shank of the shoe to be secured in a longitudinal position relative to the sole.

The invention relates to a sole component for a shoe suitable for use with different heels. The sole component comprises a front, a middle and a rear sole portion and comprises a mechanism for adjusting the sole curvature in a transition region between the front and the middle sole portion. The mechanism comprises a rotatable supporting element which is provided in such a way that it may have a first angular position which causes a first sole curvature in the transition region and a second angular position which causes a second sole curvature in the transition region, wherein the first sole curvature is different from the second sole curvature.

A shoe assembly includes a front sole section, a rear sole section, a heel, and a hinge. The front sole section has a front sole section rear edge. The rear sole section includes a rear sole section front edge, a shank, and a release button. The heel may be removably attached to the shank and may be released from a locked position by the release button. The hinge connects the front sole section and the rear sole section. The hinge is perpendicular to a rear sole section axis.

There are disclosed high heel shoes where separate components combine to create load balancing internal footwear technology. A two-piece system includes interlocking toe bed and shank constructed of complex three dimensional curved surfaces which create an intricately sculpted volume to provide structural support down the length of the entire foot. The toe bed provides a wide base and keeps the big toe pointed straight (at an approximately 10 angle). A heel maximizes the surface area of the bottom of the heel at the point of strike with the ground while retaining a minimal and aesthetically appealing silhouette from the side view. The toe bed and shank feature a composition of layered materials which when combined work to provide both stability and shock absorption to the ball of the foot during the foot strike of walking. An internal support structure provides a padded barrier and intermediary between the rigidity of the shank and the softness of the shoe upper.

Provided is a shoe with a replaceable screw-on heel.

A device for attaching removable interchangeable heels for shoes. A system for locking and unlocking interchangeable heels in order to change heels as desired, while keeping the same pair of shoes, includes a base with tenon, called the housing, wherein a flat locking spring is located, and a mortise part wherein a second flat spring is inserted. The mortise and tenon assembly is locked when the two flat springs, having complementary shapes, come into contact and immobilize one another. The user can act on the tab of the locking flat spring in order to rotate it and unlock the heel. The flat spring automatically returns to its initial position due to its elasticity, when the user releases it.

An adjustable height shoe can include a shoe shank member extending between a heel end to a toe end of the shoe. A heel member can be removably attachable, at an attachment end thereof, to the shoe shank member. The attachment end of the heel member is insertable into the shoe shank member in a first direction to create a first shoe configuration and the attachment end of the heel member is insertable into the shoe shank member in a second direction to create a second shoe configuration. The shoe can further include a shoe shank member hole and one or more heel member holes that can align with each other when the attachment end of the heel member is inserted into the shoe shank member. A connector can fit into the aligned holes to maintain a connection between the shoe shank member and the heel member.
