The present invention may provide various electric receiver arrangements which may be used to provide wireless power transmission using suitable power transmission techniques such as pocket-forming. In some embodiments, receivers may include at least one antenna connected to at least one rectifier and one power converter. In other embodiments, receivers including a plurality of antennas, a plurality of rectifiers or a plurality of power converters may be provided. In addition, receivers may include communications components which may allow for communication to various electronic equipment including transmitters, phones, computers and others. Lastly, various implementation arrangements may be provided for including receivers in electronic devices.

An insole covering system for an insole removably positioned within a shoe includes a sleeve configured to receive the insole such that the insole is covered by the sleeve. The sleeve generally has a tubular structure with a top side opposite a bottom side and an exterior surface. The sleeve has an opening therein extending inwardly into the exterior surface from the bottom side, the opening providing access to an interior pocket of the sleeve, the interior pocket being configured to receive the insole of the user's shoe.

An apparatus that assists foot movement includes a normally twisted plate configured to interact with the foot. The foot has a pronation axis, and the normally twisted plate is biased and configured to twist about a plate axis that substantially approximates the pronation axis in response to a load received from the foot during foot pronation. As the foot pronates, the plate twists to apply a non-linear force substantially about the plate axis.

An active suspension orthotic support system is disclosed. The suspension orthotic support system comprises at least one variable resistance beam extending from a heel section to a mid-arch section of the footwear, wherein rotation of the variable resistance beam from a first position to a second position causes a resistance provided by the variable resistance beam to vary between a minimum resistance to a maximum resistance.

Foot-supporting elements for articles of footwear or other products may include: (a) a first diagonally-oriented plate that extends from a lateral heel location of an article of footwear to a medial forefoot location of the article of footwear; and (b) a second diagonally-oriented plate that extends from a medial heel location of the article of footwear to a lateral forefoot location of the article of footwear. These foot-supporting elements may be utilized in foot-receiving devices that may include: (a) a foot-covering member (such as an upper); and (b) a foot-supporting element engaged with the foot-covering member.

An insole made of two membrane foils, between which a liquid is provided. The membrane foils have very little elasticity and high stiffness to respond quickly to load by pushing liquid quickly from an area under the foot to another area of the foot, by which the balance response is made faster for a person who uses such insoles. Especially in the field of multiple sclerosis, post-stroke rehabilitation, golf and race have such insoles have proven to be very advantageous.

A customizable arch support system for use in fashionable high heeled shoes, designed to provide superior configurability and comfort for the wearer. More particularly, the system provides configurability so that it will provide superior support and comfort for the wearer, while maintaining minimal cross section profile which causes less limitations for the shoe designer.
