Exemplary embodiments are directed to a pedal for a bicycle that includes a body, a spindle secured to the body and for connection to the bicycle, a first magnetic platter, and a second magnetic platter overlaying the first magnetic platter. The first and second magnetic platters each include a plurality of blocks formed of a material that can be magnetized, and a plurality of permanent magnet plates arranged so as to magnetize the blocks with either a magnetic north or magnetic south polarity with adjacent blocks being magnetized with opposite magnetic polarities. The second magnetic platter is movable with respect to the first magnetic platter by a ferrous metal cleat between a first position where the pedal is in a magnetically inactive state and a second position where the pedal is in a magnetically active state magnetically securing the cleat to the second magnetic platter.

A fastening element configured for attachment to a wearable clothing or accessory substrate whereby ornamental elements are configured for removable fastening thereto for changeable decorative appearance of the clothing or accessory wherein the fastening element is ornamental in appearance whereby it is aesthetically viewable with or without ornamental elements fastened thereto and whereby the fastener is able to be integrated with appearance of the ornamental element or completely hidden by the ornamental elements.

An energy harvesting system including a channel, a first coil having a clockwise rotation around the channel, a second coil having a counter clockwise rotation around the channel, and magnetic train. The magnetic train is configured to move through the channel, the magnetic train including a plurality of oppositely-alternating magnets.

A heel pad for placement within a shoe and a method of use. The heel pad includes a pliable body, a filler element contained within the pliable body, and a malleable member fastened within the pliable body and extending along at least part of a length of the pliable body. In use, the heel pad is positioned in a heel section of the shoe. A longitudinal end of the heel pad is folded along an upper edge of the heel section of the shoe. The folded longitudinal end of the heel pad is affixed to an outer surface of the heel section of the shoe.

Coupling assembly between a footwear and a sport equipment comprising at least one housing on the footwear near the sole suitable for receiving a first metallic element, a binding, on the sport equipment, provided with a seat for the insertion of the footwear, the binding being equipped with at least a second metallic element positioned in the seat, the first or the second metal element being an electromagnet, which when activated is magnetically bound to the other element.

A shock absorbing system for force attenuation, impact modification or reduction, employs an envelope having a chamber containing a first working fluid, the envelope deformable in response to the impulse to attenuate impact force. A plurality of resilient supplemental absorber elements dispersed within the chamber. The plurality of resilient supplemental absorber elements are deformable in response to the force to assist in attenuating impact force and provide additional resilient restoring force to return the envelope to a pre-impact shape. In alternative implementations, a unitary cell for energy dissipation employs an envelope having a chamber containing a first working fluid and an inner element contained within the chamber and having an inner chamber containing a second working fluid.

A foot presence sensor system for an active article of footwear can include a sensor housing configured to be disposed at or in an insole of the article, and a controller circuit, disposed within the sensor housing, configured to trigger one or more automated functions of the footwear based on a foot presence indication. In an example, the sensor system includes a capacitive sensor configured to sense changes in a capacitance signal in response to proximity of a body. A dielectric member can be provided between the capacitive sensor and the body to enhance an output signal from the sensor.

A clipless pedal system is provided. In various embodiments, systems of the present disclosure comprise pedals and cleats for interaction with the pedals. At least one of a pedal and an associated cleat comprises a magnet, and at least one of the pedal and the associated cleat comprises a ferrous metal for interaction with the magnet. Geometric features are provided to enable both a secure connection between a cleat and a pedal and to enable a user-friendly release of the cleat from the pedal.

An insole may include an insole body in a shape receivable in a shoe; an electronic element provided in the insole body; a connection line configured to electrically connect to the electronic element and including a contact terminal exposed to the outside of the insole body; and a connector including a detachable member configured to at least partially protrude outward from the insole body and configured to support the contact terminal.

A smartphone or other mobile computer device, general purpose or specialized, wherein the smartphone device is configured to actively control the configuration of one or more bladders, compartments, chambers or internal sipes and one or more sensors located in either one or both of a sole or a removable inner sole insert of the footwear of the user and/or located in an apparatus worn or carried by the user, glued unto the user, or implanted in the user. The one or more bladders, compartments, chambers, or sipes, and one or more sensors are configured for computer control. A sole and/or a removable inner sole insert for footwear, including one or more bladders, compartments, chambers, internal sipes and sensors in the sole and/or in a removable insert; or on an insole; all being configured for control by a smartphone or other mobile computer device, general purpose or specialized.
