A footwear system can employ a brake and/or a clutch, such as a one-way clutch, to convert human motion into usable electricity. The brake and one-way clutch can be used together, such as on opposite ends of a spring. During a storage phase, the brake can be engaged and the one-way clutch disengaged so the spring stores an energy. After the storage phase, the brake can be removed to initiate the release phase since the brake is not stopping the spring, but the one-way clutch allows the stored energy to be released.

A high heel footwear including a heel tip assembly and a heel assembly. The heel tip assembly includes a top lift abutting against the heel, a rigid shaft member having a threaded portion, and a first wedge-lock feature configured to prevent the top lift from rotating. The heel assembly includes a threaded insert, a spring, a hollow insert, and a second wedge-lock feature. The threaded insert is received inside an opening formed in the heel to receive the threaded portion of the rigid shaft member. The spring is also received inside the opening and abuts against the threaded insert. The hollow insert abuts against the spring. The rigid shaft member passes through the threaded insert, the spring, and the hollow insert. The second wedge-lock feature locks with the first wedge-lock feature to retain the top lift on the end of the heel.

A wearable system, such as a footwear system, can employ a generator. The generator can be an electro-mechanical generator with a portion that spins to create an electricity. The portion that spins can be spun in such a manner that it does not stop, but instead a next spin beings before a previous spin completes. This can repeat until the generator reaches a terminal velocity.

The present invention relates to a shock-absorbing heel provided with a shock absorber for mitigating the load applied to the sole of a foot when walking and, more specifically, to a shock-absorbing heel provided with a shock absorber and attached to a high heel, the shock-absorbing heel comprising, an outer heel fixedly mounted to the rear surface of the sole of a high heel (shoe), an inner heel which has an elastic spring mounted to the upper side thereof and is coupled to the inside of the outer heel, and a bottom heel which is fixedly mounted to a lower end portion of the inner heel so as to be replaceable, wherein a cylindrical protective cap which is inserted so as to prevent the lower end portion of the inner heel from being exposed to the outside is provided on a lower end portion of the outer heel, and a fastening cover coupled to the inner heel above the elastic spring is inserted into the outer heel. Thus, the outer heel slides up and down by virtue of the elastic spring to mitigate shock when walking.
