Presented are systems, methods, and devices for manufacturing articles of footwear using sacrificial straps to secure segments of the footwear to a manufacturing fixture. A method for manufacturing an article of footwear, such as an athletic shoe, includes providing first and second segments of the footwear's upper, such as the vamp and heel counter. A sacrificial strap is removably attached at opposing ends thereof to the first segment, e.g., proximate a read edge of the vamp. The first segment is placed on a manufacturing fixture, such as a foot-shaped last, and securely attached to the fixture by positioning the sacrificial strap around and against the fixture. The second segment of the upper is attached, e.g., via stitching or bonding, to the first segment. Once attached, the upper is removed from the manufacturing fixture, and the sacrificial strap is cut, torn or otherwise permanently disconnected from the footwear.

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 footwear sole apparatus which has a base member and at least one insert (principal insert and/or heel insert) as well as one or more fail-safe interconnectivity mechanisms, comprised of a configuration to fit or replace the sole or partial sole of a pair or pairs of footwear. The base member is either pre-attached to a new shoe(s) or fitted onto the sole of an existing shoe(s). The base member can be attached to the insert(s), having one or more fail-safe mechanisms to enhance interconnectivity of the base member and insert(s).

A heel integration system for a shoe includes an insert configured to be disposed in the shoe and to receive an AFO brace. The insert has a heel portion and an ankle portion. The ankle portion has at least one recess formed on an interior surface thereof. The recess is configured to receive at least one projection of the AFO brace. Advantageously, the heel integration system allows wearers with AFO braces to utilize properly sized shoes. It should be appreciated that the insert provides a predetermined clearance within the shoe for the AFO brace. Additionally, the insert of the heel integration system may militate against damage to the interior of the shoe that may otherwise be caused by friction between the AFO brace and the shoe where the insert is not utilized.

The invention relates to an inner pad reinforcement device of a sole. It comprises an insole having a forefoot zone, an arch zone, a heel zone and a shoe heel integrally formed on the heel zone and having a receiving slot; and a reinforcement unit having a heal seat for inserting into the receiving slot and a supporting part.

An interchangeable heel device for a shoe is disclosed. The device has an upper base and a key. The upper base has a receiving recess that is configured to be located in a heel area of a shoe below an insole of the shoe. The key is for attaching to an upper side of a heel of a shoe. The key is movable within the receiving recess between a released position and an engaged position. In the engaged position each key first engagement portion is engaged with one of the receiving first engagement portions and each key second engagement portions is engaged with one of the receiving second engagement portions to join the key to the perimeter and the heel to the sole. In the released position each key first engagement portion is aligned with one of the receiving recessed regions and the key is removable from the receiving recess.

A heeled shoe including a heel located in the rear part of the shoe and configured so that it is almost completely hidden from view when the shoe is in use and the use of such shoe.
